NAME
XF86Config - Configuration File for XFree86
INTRODUCTION
XFree86 supports several mechanisms for supplying/obtaining
configuration and run-time parameters: command line options,
environment variables, the XF86Config configuration file,
auto-detection, and fallback defaults. When the same infor-
mation is supplied in more than one way, the highest pre-
cedence mechanism is used. The list of mechanisms is
ordered from highest precedence to lowest. Note that not
all parameters can be supplied via all methods. The avail-
able command line options and environment variables (and
some defaults) are described in the Xserver(1) and
XFree86(1) manual pages. Most configuration file parame-
ters, with their defaults, are described below. Driver and
module specific configuration parameters are described in
the relevant driver or module manual page.
Starting with version 4.4, XFree86 has support for generat-
ing a usable configuration at run-time when no XF86Config
file is provided. The initial version of this automatic
configuration support is targeted at the most popular
hardware and software platforms supported by XFree86. Some
details about how this works can be found in the XFree86(1)
and getconfig(1) manual pages.
Starting with version 4.5, it is possible for this automati-
cally generated configuration to supplement a partial static
configuration. The partial static configuration can be used
to provide non-default configuration details for things that
are not currently handled by the automatic configuration
mechanism.
DESCRIPTION
XFree86 uses a configuration file called XF86Config for its
initial setup. This configuration file is searched for in
the following places when the server is started as a normal
user:
/etc/X11/<cmdline>
/usr/X11R6/etc/X11/<cmdline>
/etc/X11/$XF86CONFIG
/usr/X11R6/etc/X11/$XF86CONFIG
/etc/X11/XF86Config-4
/etc/X11/XF86Config
/etc/XF86Config
/usr/X11R6/etc/X11/XF86Config.<hostname>
/usr/X11R6/etc/X11/XF86Config-4
/usr/X11R6/etc/X11/XF86Config
/usr/X11R6/lib/X11/XF86Config.<hostname>
/usr/X11R6/lib/X11/XF86Config-4
XFree86 Version 4.5.0 1
XF86Config(5) UNIX Programmer's Manual XF86Config(5)
/usr/X11R6/lib/X11/XF86Config
where <cmdline> is a relative path (with no ".." components)
specified with the -xf86config command line option,
$XF86CONFIG is the relative path (with no ".." components)
specified by that environment variable, and <hostname> is
the machine's hostname as reported by gethostname(3).
When the XFree86 server is started by the "root" user, the
config file search locations are as follows:
<cmdline>
/etc/X11/<cmdline>
/usr/X11R6/etc/X11/<cmdline>
$XF86CONFIG
/etc/X11/$XF86CONFIG
/usr/X11R6/etc/X11/$XF86CONFIG
$HOME/XF86Config
/etc/X11/XF86Config-4
/etc/X11/XF86Config
/etc/XF86Config
/usr/X11R6/etc/X11/XF86Config.<hostname>
/usr/X11R6/etc/X11/XF86Config-4
/usr/X11R6/etc/X11/XF86Config
/usr/X11R6/lib/X11/XF86Config.<hostname>
/usr/X11R6/lib/X11/XF86Config-4
/usr/X11R6/lib/X11/XF86Config
where <cmdline> is the path specified with the -xf86config
command line option (which may be absolute or relative),
$XF86CONFIG is the path specified by that environment vari-
able (absolute or relative), $HOME is the path specified by
that environment variable (usually the home directory), and
<hostname> is the machine's hostname as reported by gethost-
name(3).
The XF86Config file is composed of a number of sections
which may be present in any order. Each section has the
form:
Section "SectionName"
SectionEntry
...
EndSection
The section names are:
Files File pathnames
ServerFlags Server flags
Module Dynamic module loading
InputDevice Input device description
Device Graphics device description
XFree86 Version 4.5.0 2
XF86Config(5) UNIX Programmer's Manual XF86Config(5)
VideoAdaptor Xv video adaptor description
Monitor Monitor description
Modes Video modes descriptions
Screen Screen configuration
ServerLayout Overall layout
DRI DRI-specific configuration
Vendor Vendor-specific configuration
The following obsolete section names are still recognised
for compatibility purposes. In new config files, the Input-
Device section should be used instead.
Keyboard Keyboard configuration
Pointer Pointer/mouse configuration
The old XInput section is no longer recognised.
The ServerLayout sections are at the highest level. They
bind together the input and output devices that will be used
in a session. The input devices are described in the Input-
Device sections. Output devices usually consist of multiple
independent components (e.g., and graphics board and a moni-
tor). These multiple components are bound together in the
Screen sections, and it is these that are referenced by the
ServerLayout section. Each Screen section binds together a
graphics board and a monitor. The graphics boards are
described in the Device sections, and the monitors are
described in the Monitor sections.
Config file keywords are case-insensitive, and "_" charac-
ters are ignored. Most strings (including Option names) are
also case-insensitive, and insensitive to white space and
"_" characters.
Each config file entry usually takes up a single line in the
file. They consist of a keyword, which is possibly followed
by one or more arguments, with the number and types of the
arguments depending on the keyword. The argument types are:
Integer an integer number in decimal, hex or octal
Real a floating point number
String a string enclosed in double quote marks (")
Note: hex integer values must be prefixed with "0x", and
octal values with "0".
A special keyword called Option may be used to provide
free-form data to various components of the server. The
Option keyword takes either one or two string arguments.
The first is the option name, and the optional second argu-
ment is the option value. Some commonly used option value
types include:
XFree86 Version 4.5.0 3
XF86Config(5) UNIX Programmer's Manual XF86Config(5)
Integer an integer number in decimal, hex or octal
Real a floating point number
String a sequence of characters
Boolean a boolean value (see below)
Frequency a frequency value (see below)
Note that all Option values, not just strings, must be
enclosed in quotes.
Boolean options may optionally have a value specified. When
no value is specified, the option's value is TRUE. The fol-
lowing boolean option values are recognised as TRUE:
1, on, true, yes
and the following boolean option values are recognised as
FALSE:
0, off, false, no
If an option name is prefixed with "No", then the option
value is negated.
Example: the following option entries are equivalent:
Option "Accel" "Off"
Option "NoAccel"
Option "NoAccel" "On"
Option "Accel" "false"
Option "Accel" "no"
Frequency option values consist of a real number that is
optionally followed by one of the following frequency units:
Hz, k, kHz, M, MHz
When the unit name is omitted, the correct units will be
determined from the value and the expectations of the
appropriate range of the value. It is recommended that the
units always be specified when using frequency option values
to avoid any errors in determining the value.
FILES SECTION
The config file may have multiple Files sections. These are
used to specify some path names required by the server.
Earlier Files sections have priority over later sections.
This means that a path name specified in a Files section
cannot be overridden by a later Files section (this
behaviour may change in the future). Some of these paths
can also be set from the command line (see Xserver(1) and
XFree86(1)). The command line settings override the values
specified in the config file. The Files section is
XFree86 Version 4.5.0 4
XF86Config(5) UNIX Programmer's Manual XF86Config(5)
optional, as are all of the entries that may appear in it.
The entries that can appear in this section are:
Identifier "name"
specifies an optional identifying name for the Files
section.
FontPath "path"
sets the search path for fonts. This path is a comma
separated list of font path elements which the
XFree86 server searches for font databases. Multiple
FontPath entries may be specified, and they will be
concatenated to build up the fontpath used by the
server. Font path elements may be either absolute
directory paths, or a font server identifier. Font
server identifiers have the form:
<trans>/<hostname>:<port-number>
where <trans> is the transport type to use to connect
to the font server (e.g., unix for UNIX-domain sock-
ets or tcp for a TCP/IP connection), <hostname> is
the hostname of the machine running the font server,
and <port-number> is the port number that the font
server is listening on (usually 7100).
When this entry is not specified in the config file,
the server falls back to the compiled-in default font
path, which contains the following font path ele-
ments:
/usr/X11R6/lib/X11/fonts/misc/
/usr/X11R6/lib/X11/fonts/Speedo/
/usr/X11R6/lib/X11/fonts/Type1/
/usr/X11R6/lib/X11/fonts/CID/
/usr/X11R6/lib/X11/fonts/75dpi/
/usr/X11R6/lib/X11/fonts/100dpi/
The recommended font path contains the following font
path elements:
/usr/X11R6/lib/X11/fonts/local/
/usr/X11R6/lib/X11/fonts/misc/
/usr/X11R6/lib/X11/fonts/75dpi/:unscaled
/usr/X11R6/lib/X11/fonts/100dpi/:unscaled
/usr/X11R6/lib/X11/fonts/Type1/
/usr/X11R6/lib/X11/fonts/CID/
/usr/X11R6/lib/X11/fonts/Speedo/
/usr/X11R6/lib/X11/fonts/75dpi/
/usr/X11R6/lib/X11/fonts/100dpi/
XFree86 Version 4.5.0 5
XF86Config(5) UNIX Programmer's Manual XF86Config(5)
Font path elements that are found to be invalid are
removed from the font path when the server starts up.
RGBPath "path"
sets the path name for the RGB color database. When
this entry is not specified in the config file, the
server falls back to the compiled-in default RGB
path, which is:
/usr/X11R6/lib/X11/rgb
Note that an implicit .txt is added to this path if the
server was compiled to use text rather than binary format
RGB color databases.
ModulePath "path"
sets the search path for loadable XFree86 server
modules. This path is a comma separated list of
directories which the XFree86 server searches for
loadable modules loading in the order specified.
Multiple ModulePath entries may be specified, and
they will be concatenated to build the module search
path used by the server.
Options
Option flags may be specified in Files sections.
SERVERFLAGS SECTION
The config file may have multiple ServerFlags sections.
These are used to specify some global XFree86 server
options. Earlier ServerFlags sections have priority over
later sections. This means that an option specified in a
ServerFlags section cannot be overridden by a later Server-
Flags section. Except for the Identifier entry, all of the
entries in this section are Options, although for compati-
bility purposes some of the old style entries are still
recognised. Those old style entries are not documented
here, and using them is discouraged. The ServerFlags sec-
tion is optional, as are the entries that may be specified
in it.
Options specified in this section (with the exception of the
"DefaultServerLayout" Option) may be overridden by Options
specified in the active ServerLayout section. Options with
command line equivalents are overridden when their command
line equivalent is used. Entries recognised by this section
are:
Identifier "name"
specifies an optional identifying name for the Ser-
verFlags section.
XFree86 Version 4.5.0 6
XF86Config(5) UNIX Programmer's Manual XF86Config(5)
Option "DefaultServerLayout" "layout-id"
This specifies the default ServerLayout section to
use in the absence of the -layout command line
option.
Option "NoTrapSignals" "boolean"
This prevents the XFree86 server from trapping a
range of unexpected fatal signals and exiting
cleanly. Instead, the XFree86 server will die and
drop core where the fault occurred. The default
behaviour is for the XFree86 server to exit cleanly,
but still drop a core file. In general you never
want to use this option unless you are debugging an
XFree86 server problem and know how to deal with the
consequences.
Option "DontVTSwitch" "boolean"
This disallows the use of the Ctrl+Alt+Fn sequence
(where Fn refers to one of the numbered function
keys). That sequence is normally used to switch to
another "virtual terminal" on operating systems that
have this feature. When this option is enabled, that
key sequence has no special meaning and is passed to
clients. Default: off.
Option "DontZap" "boolean"
This disallows the use of the Ctrl+Alt+Backspace
sequence. That sequence is normally used to ter-
minate the XFree86 server. When this option is
enabled, that key sequence has no special meaning and
is passed to clients. Default: off.
Option "DontZoom" "boolean"
This disallows the use of the Ctrl+Alt+Keypad-Plus
and Ctrl+Alt+Keypad-Minus sequences. These sequences
allows you to switch between video modes. When this
option is enabled, those key sequences have no spe-
cial meaning and are passed to clients. Default:
off.
Option "DisableVidModeExtension" "boolean"
This disables the parts of the VidMode extension used
by the xvidtune client that can be used to change the
video modes. Default: the VidMode extension is
enabled.
Option "AllowNonLocalXvidtune" "boolean"
This allows the xvidtune client (and other clients
that use the VidMode extension) to connect from
another host. Default: off.
Option "DisableModInDev" "boolean"
XFree86 Version 4.5.0 7
XF86Config(5) UNIX Programmer's Manual XF86Config(5)
This disables the parts of the XFree86-Misc extension
that can be used to modify the input device settings
dynamically. Default: that functionality is enabled.
Option "AllowNonLocalModInDev" "boolean"
This allows a client to connect from another host and
change keyboard and mouse settings in the running
server. Default: off.
Option "AllowMouseOpenFail" "boolean"
This allows the server to start up even if the mouse
device can't be opened/initialised. Default: false.
Option "VTInit" "command"
Runs command after the VT used by the server has been
opened. The command string is passed to "/bin/sh -c",
and is run with the real user's id with stdin and
stdout set to the VT. The purpose of this option is
to allow system dependent VT initialisation commands
to be run. This option should rarely be needed.
Default: not set.
Option "VTSysReq" "boolean"
enables the SYSV-style VT switch sequence for non-
SYSV systems which support VT switching. This
sequence is Alt-SysRq followed by a function key
(Fn). This prevents the XFree86 server trapping the
keys used for the default VT switch sequence, which
means that clients can access them. Default: off.
Option "XkbDisable" "boolean"
disable/enable the XKEYBOARD extension. The -kb com-
mand line option overrides this config file option.
Default: XKB is enabled.
Option "BlankTime" "time"
sets the inactivity timeout for the blanking phase of
the screensaver. time is in minutes. This is
equivalent to the XFree86 server's `-s' flag, and the
value can be changed at run-time with xset(1).
Default: 10 minutes.
Option "StandbyTime" "time"
sets the inactivity timeout for the "standby" phase
of DPMS mode. time is in minutes, and the value can
be changed at run-time with xset(1). Default: 20
minutes. This is only suitable for VESA DPMS compa-
tible monitors, and may not be supported by all video
drivers. It is only enabled for screens that have
the "DPMS" option set (see the MONITOR section
below).
XFree86 Version 4.5.0 8
XF86Config(5) UNIX Programmer's Manual XF86Config(5)
Option "SuspendTime" "time"
sets the inactivity timeout for the "suspend" phase
of DPMS mode. time is in minutes, and the value can
be changed at run-time with xset(1). Default: 30
minutes. This is only suitable for VESA DPMS compa-
tible monitors, and may not be supported by all video
drivers. It is only enabled for screens that have
the "DPMS" option set (see the MONITOR section
below).
Option "OffTime" "time"
sets the inactivity timeout for the "off" phase of
DPMS mode. time is in minutes, and the value can be
changed at run-time with xset(1). Default: 40
minutes. This is only suitable for VESA DPMS compa-
tible monitors, and may not be supported by all video
drivers. It is only enabled for screens that have
the "DPMS" option set (see the MONITOR section
below).
Option "Pixmap" "bpp"
This sets the pixmap format to use for depth 24.
Allowed values for bpp are 24 and 32. Default: 32
unless driver constraints don't allow this (which is
rare). Note: some clients don't behave well when
this value is set to 24.
Option "PC98" "boolean"
Specify that the machine is a Japanese PC-98 machine.
This should not be enabled for anything other than
the Japanese-specific PC-98 architecture. Default:
auto-detected.
Option "Log" "logflag"
This option enables special handling for log files
that may be useful when debugging certain types of
problems. The values for logflag are Flush and Sync.
Flush causes the log file buffer to be flushed after
each write. Sync causes the log file buffer to be
flushed and the file data to be written to the disk
after each write. The default is for neither of
these flags to be enabled. Enabling these flags dur-
ing normal operation may degrade performance and/or
lengthen startup time.
Option "NoPM" "boolean"
Disables something to do with power management
events. Default: PM enabled on platforms that sup-
port it.
Option "Xinerama" "boolean"
enable or disable XINERAMA extension. Default is
XFree86 Version 4.5.0 9
XF86Config(5) UNIX Programmer's Manual XF86Config(5)
disabled.
Option "AllowDeactivateGrabs" "boolean"
This option enables the use of the Ctrl+Alt+Keypad-
Divide key sequence to deactivate any active keyboard
and mouse grabs. Default: off.
Option "AllowClosedownGrabs" "boolean"
This option enables the use of the Ctrl+Alt+Keypad-
Multiply key sequence to kill clients with an active
keyboard or mouse grab as well as killing any appli-
cation that may have locked the server, normally
using the XGrabServer(3) Xlib function. Default:
off.
Note that the options AllowDeactivateGrabs and
AllowClosedownGrabs will allow users to remove the
grab used by screen saver/locker programs. An API was
written to such cases. If you enable this option,
make sure your screen saver/locker is updated.
Option "HandleSpecialKeys" "when"
This option controls when the server uses the builtin
handler to process special key combinations (such as
Ctrl+Alt+Backspace). Normally the XKEYBOARD extension
keymaps will provide mappings for each of the special
key combinations, so the builtin handler is not
needed unless the XKEYBOARD extension is disabled.
The value of when can be Always, Never, or When-
Needed. Default: Use the builtin handler only if
needed. The server will scan the keymap for a map-
ping to the Terminate action and, if found, use XKEY-
BOARD for processing actions, otherwise the builtin
handler will be used.
MODULE SECTION
The config file may have multiple Module section. They are
used to specify additional XFree86 server modules to be
loaded. This section is ignored when the XFree86 server is
built in static form. The types of modules normally loaded
in this section are XFree86 server extension modules, and
font rasteriser modules. Most other module types are loaded
automatically when they are needed via other mechanisms.
The Module section is optional, as are all of the entries
that may be specified in it.
Identifier "name"
specifies an optional identifying name for the Module
section.
Options
Option flags may be specified in Module sections.
XFree86 Version 4.5.0 10
XF86Config(5) UNIX Programmer's Manual XF86Config(5)
Entries that identify which modules to pre-load may be in
two forms. The first and most commonly used form is an entry
that uses the Load keyword, as described here:
Load "modulename"
This instructs the server to load the module called
modulename. The module name given should be the
module's standard name, not the module file name.
The standard name is case-sensitive, and does not
include the "lib" prefix, or the ".a", ".o", or ".so"
suffixes.
Example: the Type 1 font rasteriser can be loaded
with the following entry:
Load "type1"
The second form of entry is a SubSection, with the subsec-
tion name being the module name, and the contents of the
SubSection being Options that are passed to the module when
it is loaded.
Example: the extmod module (which contains a miscellaneous
group of server extensions) can be loaded, with the
XFree86-DGA extension disabled by using the following entry:
SubSection "extmod"
Option "omit XFree86-DGA"
EndSubSection
Modules are searched for in each directory specified in the
ModulePath search path, and in the drivers, input, exten-
sions, fonts, and internal subdirectories of each of those
directories. In addition to this, operating system specific
subdirectories of all the above are searched first if they
exist.
To see what font and extension modules are available, check
the contents of the following directories:
/usr/X11R6/lib/modules/fonts
/usr/X11R6/lib/modules/extensions
The "bitmap" font modules is loaded automatically. It is
recommended that at very least the "extmod" extension module
be loaded. If it isn't some commonly used server extensions
(like the SHAPE extension) will not be available.
INPUTDEVICE SECTION
The config file may have multiple InputDevice sections.
There will normally be at least two: one for the core (pri-
mary) keyboard, and one of the core pointer. If either of
XFree86 Version 4.5.0 11
XF86Config(5) UNIX Programmer's Manual XF86Config(5)
these two is missing, a default configuration for the miss-
ing ones will be used. Currently the default configuration
may not work as expected on all platforms.
InputDevice sections have the following format:
Section "InputDevice"
Identifier "name"
Driver "inputdriver"
options
...
EndSection
The Identifier and Driver entries are required in all Input-
Device sections. All other entries are optional.
The Identifier entry specifies the unique name for this
input device. The Driver entry specifies the name of the
driver to use for this input device. When using the loadable
server, the input driver module "inputdriver" will be loaded
for each active InputDevice section. An InputDevice section
is considered active if it is referenced by an active Ser-
verLayout section, if it is referenced by the -keyboard or
-pointer command line options, or if it is selected impli-
citly as the core pointer or keyboard device in the absence
of such explicit references. The most commonly used input
drivers are "keyboard" and "mouse".
In the absence of an explicitly specified core input device,
the first InputDevice marked as CorePointer (or CoreKey-
board) is used. If there is no match there, the first
InputDevice that uses the "mouse" (or "keyboard" or "kbd")
driver is used. The final fallback is to use built-in
default configurations.
InputDevice sections recognise some driver-independent
Options, which are described here. See the individual input
driver manual pages for a description of the device-specific
options.
Option "CorePointer"
When this is set, the input device is installed as
the core (primary) pointer device. There must be
exactly one core pointer. If this option is not set
here, or in the ServerLayout section, or from the
-pointer command line option, then the first input
device that is capable of being used as a core
pointer will be selected as the core pointer. This
option is implicitly set when the obsolete Pointer
section is used.
Option "CoreKeyboard"
XFree86 Version 4.5.0 12
XF86Config(5) UNIX Programmer's Manual XF86Config(5)
When this is set, the input device is to be installed
as the core (primary) keyboard device. There must be
exactly one core keyboard. If this option is not set
here, in the ServerLayout section, or from the -key-
board command line option, then the first input dev-
ice that is capable of being used as a core keyboard
will be selected as the core keyboard. This option is
implicitly set when the obsolete Keyboard section is
used.
Option "AlwaysCore" "boolean"
Option "SendCoreEvents" "boolean"
Both of these options are equivalent, and when
enabled cause the input device to always report core
events. This can be used, for example, to allow an
additional pointer device to generate core pointer
events (like moving the cursor, etc).
Option "HistorySize" "number"
Sets the motion history size. Default: 0.
Option "SendDragEvents" "boolean"
???
DEVICE SECTION
The config file may have multiple Device sections. There
must be at least one, for the video card being used.
Device sections have the following format:
Section "Device"
Identifier "name"
Driver "driver"
entries
...
EndSection
The Identifier and Driver entries are required in all Device
sections. All other entries are optional.
The Identifier entry specifies the unique name for this
graphics device. The Driver entry specifies the name of the
driver to use for this graphics device. When using the load-
able server, the driver module "driver" will be loaded for
each active Device section. A Device section is considered
active if it is referenced by an active Screen section.
Device sections recognise some driver-independent entries
and Options, which are described here. Not all drivers make
use of these driver-independent entries, and many of those
that do don't require them to be specified because the
XFree86 Version 4.5.0 13
XF86Config(5) UNIX Programmer's Manual XF86Config(5)
information is auto-detected. See the individual graphics
driver manual pages for further information about this, and
for a description of the device-specific options. Note that
most of the Options listed here (but not the other entries)
may be specified in the Screen section instead of here in
the Device section.
BusID "bus-id"
This specifies the bus location of the graphics card.
For PCI/AGP cards, the bus-id string has the form
PCI:bus:device:function (e.g., "PCI:1:0:0" might be
appropriate for an AGP card). This field is usually
optional in single-head configurations when using the
primary graphics card. In multi-head configurations,
or when using a secondary graphics card in a single-
head configuration, this entry is mandatory. Its
main purpose is to make an unambiguous connection
between the device section and the hardware it is
representing. This information can usually be found
by running the XFree86 server with the -scanpci com-
mand line option.
Screen number
This option is mandatory for cards where a single PCI
entity can drive more than one display (i.e., multi-
ple CRTCs sharing a single graphics accelerator and
video memory). One Device section is required for
each head, and this parameter determines which head
each of the Device sections applies to. The legal
values of number range from 0 to one less than the
total number of heads per entity. Most drivers
require that the primary screen (0) be present.
Chipset "chipset"
This usually optional entry specifies the chipset
used on the graphics board. In most cases this entry
is not required because the drivers will probe the
hardware to determine the chipset type. Don't
specify it unless the driver-specific documentation
recommends that you do.
Ramdac "ramdac-type"
This optional entry specifies the type of RAMDAC used
on the graphics board. This is only used by a few of
the drivers, and in most cases it is not required
because the drivers will probe the hardware to deter-
mine the RAMDAC type where possible. Don't specify
it unless the driver-specific documentation recom-
mends that you do.
DacSpeed speed
XFree86 Version 4.5.0 14
XF86Config(5) UNIX Programmer's Manual XF86Config(5)
DacSpeed speed-8 speed-16 speed-24 speed-32
This optional entry specifies the RAMDAC speed rating
(which is usually printed on the RAMDAC chip). The
speed is in MHz. When one value is given, it applies
to all framebuffer pixel sizes. When multiple values
are give, they apply to the framebuffer pixel sizes
8, 16, 24 and 32 respectively. This is not used by
many drivers, and only needs to be specified when the
speed rating of the RAMDAC is different from the
defaults built in to driver, or when the driver can't
auto-detect the correct defaults. Don't specify it
unless the driver-specific documentation recommends
that you do.
Clocks clock ...
specifies the pixel that are on your graphics board.
The clocks are in MHz, and may be specified as a
floating point number. The value is stored inter-
nally to the nearest kHz. The ordering of the clocks
is important. It must match the order in which they
are selected on the graphics board. Multiple Clocks
lines may be specified, and each is concatenated to
form the list. Most drivers do not use this entry,
and it is only required for some older boards with
non-programmable clocks. Don't specify this entry
unless the driver-specific documentation explicitly
recommends that you do.
ClockChip "clockchip-type"
This optional entry is used to specify the clock chip
type on graphics boards which have a programmable
clock generator. Only a few XFree86 drivers support
programmable clock chips. For details, see the
appropriate driver manual page.
VideoRam mem
This optional entry specifies the amount of video ram
that is installed on the graphics board. This is
measured in kBytes. In most cases this is not
required because the XFree86 server probes the graph-
ics board to determine this quantity. The driver-
specific documentation should indicate when it might
be needed.
BiosBase baseaddress
This optional entry specifies the base address of the
video BIOS for the VGA board. This address is nor-
mally auto-detected, and should only be specified if
the driver-specific documentation recommends it.
MemBase baseaddress
This optional entry specifies the memory base address
XFree86 Version 4.5.0 15
XF86Config(5) UNIX Programmer's Manual XF86Config(5)
of a graphics board's linear frame buffer. This
entry is not used by many drivers, and it should only
be specified if the driver-specific documentation
recommends it.
IOBase baseaddress
This optional entry specifies the IO base address.
This entry is not used by many drivers, and it should
only be specified if the driver-specific documenta-
tion recommends it.
ChipID id
This optional entry specifies a numerical ID
representing the chip type. For PCI cards, it is usu-
ally the device ID. This can be used to override the
auto-detection, but that should only be done when the
driver-specific documentation recommends it.
ChipRev rev
This optional entry specifies the chip revision
number. This can be used to override the auto-
detection, but that should only be done when the
driver-specific documentation recommends it.
TextClockFreq freq
This optional entry specifies the pixel clock fre-
quency that is used for the regular text mode. The
frequency is specified in MHz. This is rarely used.
IRQ interrupt-number
This optional entry allows an interrupt number to be
specified.
Options
Option flags may be specified in the Device sections.
These include driver-specific options and driver-
independent options. The former are described in the
driver-specific documentation. Some of the latter are
described below in the section about the Screen sec-
tion, and they may also be included here.
VIDEOADAPTOR SECTION
The config file may have multiple VideoAdaptor sections,
which may be referenced from Screen sections.
VideoAdaptor sections have the following format:
Section "VideoAdaptor"
Identifier "name"
entries
...
XFree86 Version 4.5.0 16
XF86Config(5) UNIX Programmer's Manual XF86Config(5)
SubSection "Port"
entries
...
EndSubSection
...
EndSection
The only mandatory entry in a VideoAdaptor section is the
Identifier. Other entries include:
VendorName "vendor"
This optional entry specifies the video adaptor's
manufacturer.
BoardName "model"
This optional entry specifies the video adaptor's
model name.
Options
may be specified in the VideoAdaptor section.
The Port SubSections provide information about video adaptor
ports. Each of these may contain an Identifier entry and
Options.
MONITOR SECTION
The config file may have multiple Monitor sections. There
should normally be at least one, for the monitor being used,
but a default configuration will be created when one isn't
specified.
Monitor sections have the following format:
Section "Monitor"
Identifier "name"
entries
...
EndSection
The only mandatory entry in a Monitor section is the Iden-
tifier entry.
The Identifier entry specifies the unique name for this mon-
itor. The Monitor section provides information about the
specifications of the monitor, monitor-specific Options, and
information about the video modes to use with the monitor.
Specifying video modes is optional because the server now
has a built-in list of VESA standard modes. When modes are
specified explicitly in the Monitor section (with the Modes,
ModeLine, or UseModes keywords), built-in modes with the
same names are not included. Built-in modes with different
names are, however, still implicitly included.
XFree86 Version 4.5.0 17
XF86Config(5) UNIX Programmer's Manual XF86Config(5)
The entries that may be used in Monitor sections are
described below.
VendorName "vendor"
This optional entry specifies the monitor's manufac-
turer.
ModelName "model"
This optional entry specifies the monitor's model.
HorizSync horizsync-range
gives the range(s) of horizontal sync frequencies
supported by the monitor. horizsync-range may be a
comma separated list of either discrete values or
ranges of values. A range of values is two values
separated by a dash. By default the values are in
units of kHz. They may be specified in MHz or Hz if
MHz or Hz is added to the end of the line. The data
given here is used by the XFree86 server to determine
if video modes are within the specifications of the
monitor. This information should be available in the
monitor's handbook. If this entry is omitted, a
default range of 28-33kHz is used.
VertRefresh vertrefresh-range
gives the range(s) of vertical refresh frequencies
supported by the monitor. vertrefresh-range may be a
comma separated list of either discrete values or
ranges of values. A range of values is two values
separated by a dash. By default the values are in
units of Hz. They may be specified in MHz or kHz if
MHz or kHz is added to the end of the line. The data
given here is used by the XFree86 server to determine
if video modes are within the specifications of the
monitor. This information should be available in the
monitor's handbook. If this entry is omitted, a
default range of 43-72Hz is used.
DisplaySize width height
This optional entry gives the width and height, in
millimetres, of the picture area of the monitor. If
given this is used to calculate the horizontal and
vertical pitch (DPI) of the screen.
Gamma gamma-value
Gamma red-gamma green-gamma blue-gamma
This is an optional entry that can be used to specify
the gamma correction for the monitor. It may be
specified as either a single value or as three
separate RGB values. The values should be in the
range 0.1 to 10.0, and the default is 1.0. Not all
XFree86 Version 4.5.0 18
XF86Config(5) UNIX Programmer's Manual XF86Config(5)
drivers are capable of using this information.
UseModes "modesection-id"
Include the set of modes listed in the Modes section
called modesection-id. This make all of the modes
defined in that section available for use by this
monitor.
Mode "name"
This is an optional multi-line entry that can be used
to provide definitions for video modes for the moni-
tor. In most cases this isn't necessary because the
built-in set of VESA standard modes will be suffi-
cient. The Mode keyword indicates the start of a
multi-line video mode description. The mode descrip-
tion is terminated with the EndMode keyword. The
mode description consists of the following entries:
DotClock clock
is the dot (pixel) clock rate to be used for the
mode.
HTimings hdisp hsyncstart hsyncend htotal
specifies the horizontal timings for the mode.
VTimings vdisp vsyncstart vsyncend vtotal
specifies the vertical timings for the mode.
Flags "flag" ...
specifies an optional set of mode flags, each of
which is a separate string in double quotes.
"Interlace" indicates that the mode is inter-
laced. "DoubleScan" indicates a mode where each
scanline is doubled. "+HSync" and "-HSync" can be
used to select the polarity of the HSync signal.
"+VSync" and "-VSync" can be used to select the
polarity of the VSync signal. "Composite" can be
used to specify composite sync on hardware where
this is supported. Additionally, on some
hardware, "+CSync" and "-CSync" may be used to
select the composite sync polarity.
HSkew hskew
specifies the number of pixels (towards the right
edge of the screen) by which the display enable
signal is to be skewed. Not all drivers use this
information. This option might become necessary
to override the default value supplied by the
server (if any). "Roving" horizontal lines indi-
cate this value needs to be increased. If the
last few pixels on a scan line appear on the left
of the screen, this value should be decreased.
XFree86 Version 4.5.0 19
XF86Config(5) UNIX Programmer's Manual XF86Config(5)
VScan vscan
specifies the number of times each scanline is
painted on the screen. Not all drivers use this
information. Values less than 1 are treated as
1, which is the default. Generally, the "Doub-
leScan" Flag mentioned above doubles this value.
ModeLine "name" mode-description
This entry is a more compact version of the Mode
entry, and it also can be used to specify video modes
for the monitor. is a single line format for specify-
ing video modes. In most cases this isn't necessary
because the built-in set of VESA standard modes will
be sufficient.
The mode-description is in four sections, the first
three of which are mandatory. The first is the dot
(pixel) clock. This is a single number specifying
the pixel clock rate for the mode in MHz. The second
section is a list of four numbers specifying the hor-
izontal timings. These numbers are the hdisp,
hsyncstart, hsyncend, and htotal values. The third
section is a list of four numbers specifying the
vertical timings. These numbers are the vdisp,
vsyncstart, vsyncend, and vtotal values. The final
section is a list of flags specifying other charac-
teristics of the mode. Interlace indicates that the
mode is interlaced. DoubleScan indicates a mode where
each scanline is doubled. +HSync and -HSync can be
used to select the polarity of the HSync signal.
+VSync and -VSync can be used to select the polarity
of the VSync signal. Composite can be used to specify
composite sync on hardware where this is supported.
Additionally, on some hardware, +CSync and -CSync may
be used to select the composite sync polarity. The
HSkew and VScan options mentioned above in the Modes
entry description can also be used here.
Option "DPMS" "boolean"
Set whether DPMS is enabled for the monitor. The
default is taken from the monitor's DDC/EDID informa-
tion if available, or false if not.
Option "TargetRefresh" "refresh"
Sets a target refresh rate to use for the monitor.
If the monitor has valid modes with a refresh rate
greater or equal to this value, those with a lower
refresh rate will not be considered when determining
the default resolution to use. This is improves the
default resolution selection when none is specified
explicitly. Default: TargetRefresh not used.
XFree86 Version 4.5.0 20
XF86Config(5) UNIX Programmer's Manual XF86Config(5)
Option "SyncOnGreen" "boolean"
Set whether sync-on-green should be enabled. The
availability of this option is driver-specific.
Default: false.
Option "PreferredMode" "XresxYres"
Sets a preferred resolution to use for the default
mode. By default the preferred mode resolution is
taken from the DDC/EDID data if it is available and
if it is provides a default mode preference. This is
typically true for flat panel displays, which have a
native/preferred resolution. This option is not used
of the UsePreferredMode option is false.
Option "UsePreferredMode" "boolean"
Controls whether or not a preferred mode, either
detected from the monitor's DDC/EDID data or provided
explicitly with the PreferredMode option, is used.
Default: true.
Options
Additional Option flags, including driver-specific
options, may be included in Monitor sections.
MODES SECTION
The config file may have multiple Modes sections, or none.
These sections provide a way of defining sets of video modes
independently of the Monitor sections. Monitor sections may
include the definitions provided in these sections by using
the UseModes keyword. In most cases the Modes sections are
not necessary because the built-in set of VESA standard
modes will be sufficient.
Modes sections have the following format:
Section "Modes"
Identifier "name"
entries
...
EndSection
The Identifier entry specifies the unique name for this set
of mode descriptions. The other entries permitted in Modes
sections are the Mode and ModeLine entries that are
described above in the Monitor section, as well as Options.
SCREEN SECTION
The config file may have multiple Screen sections. There
must be at least one, for the "screen" being used. A
"screen" represents the binding of a graphics device (Device
section) and one or more monitors (Monitor sections). A
XFree86 Version 4.5.0 21
XF86Config(5) UNIX Programmer's Manual XF86Config(5)
Screen section is considered "active" if it is referenced by
an active ServerLayout section or by the -screen command
line option. If neither of those is present, the first
Screen section found in the config file is considered the
active one.
Screen sections have the following format:
Section "Screen"
Identifier "name"
Device "devid"
Monitor "monid"
entries
...
SubSection "Display"
entries
...
EndSubSection
...
EndSection
The Identifier and Device entries are mandatory. All others
are optional.
The Identifier entry specifies the unique name for this
screen. The Screen section provides information specific to
the whole screen, including screen-specific Options. In
multi-head configurations, there will be multiple active
Screen sections, one for each head. The entries available
for this section are:
Device "device-id"
This mandatory entry specifies the Device section to
be used for this screen. This is what ties a
specific graphics card to a screen. The device-id
must match the Identifier of a Device section in the
config file.
Monitor monitor-num "monitor-id"
One of these entries may be given for each monitor
associated with this screen. In the absence of these
entries, at least one default monitor will be created
for the screen. The monitor-id field is mandatory,
and specifies the Monitor section being referenced.
The monitor-num field is required when more than one
monitor is being associated with the screen. Each
referenced monitor should be given a unique monitor
number. This monitor number may be given special
significance by the driver, and it is also used to
identify which Display subsection(s) are associated
with the screen/monitor. If this field is omitted in
a multiple-monitor configuration, default values will
XFree86 Version 4.5.0 22
XF86Config(5) UNIX Programmer's Manual XF86Config(5)
be assigned. This is not recommended, and this
behaviour may change in future revisions.
If a Monitor name is not specified, a default confi-
guration is used. Currently the default configura-
tion may not function as expected on all platforms.
VideoAdaptor "xv-id"
specifies an optional Xv video adaptor description to
be used with this screen.
DefaultDepth depth
specifies which color depth the server should use by
default. The -depth command line option can be used
to override this. If neither is specified, the
default depth is driver-specific, but in most cases
is 8.
DefaultFbBpp bpp
specifies which framebuffer layout to use by default.
The -fbbpp command line option can be used to over-
ride this. In most cases the driver will chose the
best default value for this. The only case where
there is even a choice in this value is for depth 24,
where some hardware supports both a packed 24 bit
framebuffer layout and a sparse 32 bit framebuffer
layout.
Options
Various Option flags may be specified in the Screen
section. Some are driver-specific and are described
in the driver documentation. Others are driver-
independent, and will eventually be described here.
Option "Accel"
Enables XAA (X Acceleration Architecture), a mechan-
ism that makes video cards' 2D hardware acceleration
available to the XFree86 server. This option is on
by default, but it may be necessary to turn it off if
there are bugs in the driver. There are many options
to disable specific accelerated operations, listed
below. Note that disabling an operation will have no
effect if the operation is not accelerated (whether
due to lack of support in the hardware or in the
driver).
Option "BiosLocation" "address"
Set the location of the BIOS for the Int10 module.
One may select a BIOS of another card for posting or
the legacy V_BIOS range located at 0xc0000 or an
alternative address (BUS_ISA). This is only useful
under very special circumstances and should be used
XFree86 Version 4.5.0 23
XF86Config(5) UNIX Programmer's Manual XF86Config(5)
with extreme care.
Option "InitPrimary" "boolean"
Use the Int10 module to initialize the primary graph-
ics card. Normally, only secondary cards are soft-
booted using the Int10 module, as the primary card
has already been initialized by the BIOS at boot
time. Default: false.
Option "NoInt10" "boolean"
Disables the Int10 module, a module that uses the
int10 call to the BIOS of the graphics card to ini-
tialize it. Default: false.
Option "NoMTRR"
Disables MTRR (Memory Type Range Register) support, a
feature of modern processors which can improve video
performance by a factor of up to 2.5. Some hardware
has buggy MTRR support, and some video drivers have
been known to exhibit problems when MTRR's are used.
Option "XaaNoCPUToScreenColorExpandFill"
Disables accelerated rectangular expansion blits from
source patterns stored in system memory (using a
memory-mapped aperture).
Option "XaaNoColor8x8PatternFillRect"
Disables accelerated fills of a rectangular region
with a full-color pattern.
Option "XaaNoColor8x8PatternFillTrap"
Disables accelerated fills of a trapezoidal region
with a full-color pattern.
Option "XaaNoDashedBresenhamLine"
Disables accelerated dashed Bresenham line draws.
Option "XaaNoDashedTwoPointLine"
Disables accelerated dashed line draws between two
arbitrary points.
Option "XaaNoImageWriteRect"
Disables accelerated transfers of full-color rec-
tangular patterns from system memory to video memory
(using a memory-mapped aperture).
Option "XaaNoMono8x8PatternFillRect"
Disables accelerated fills of a rectangular region
with a monochrome pattern.
Option "XaaNoMono8x8PatternFillTrap"
Disables accelerated fills of a trapezoidal region
XFree86 Version 4.5.0 24
XF86Config(5) UNIX Programmer's Manual XF86Config(5)
with a monochrome pattern.
Option "XaaNoOffscreenPixmaps"
Disables accelerated draws into pixmaps stored in
offscreen video memory.
Option "XaaNoPixmapCache"
Disables caching of patterns in offscreen video
memory.
Option "XaaNoScanlineCPUToScreenColorExpandFill"
Disables accelerated rectangular expansion blits from
source patterns stored in system memory (one scan
line at a time).
Option "XaaNoScanlineImageWriteRect"
Disables accelerated transfers of full-color rec-
tangular patterns from system memory to video memory
(one scan line at a time).
Option "XaaNoScreenToScreenColorExpandFill"
Disables accelerated rectangular expansion blits from
source patterns stored in offscreen video memory.
Option "XaaNoScreenToScreenCopy"
Disables accelerated copies of rectangular regions
from one part of video memory to another part of
video memory.
Option "XaaNoSolidBresenhamLine"
Disables accelerated solid Bresenham line draws.
Option "XaaNoSolidFillRect"
Disables accelerated solid-color fills of rectangles.
Option "XaaNoSolidFillTrap"
Disables accelerated solid-color fills of Bresenham
trapezoids.
Option "XaaNoSolidHorVertLine"
Disables accelerated solid horizontal and vertical
line draws.
Option "XaaNoSolidTwoPointLine"
Disables accelerated solid line draws between two
arbitrary points.
Each Screen section may optionally contain one or more
Display subsections. Those subsections provide depth, fbbpp
and monitor specific configuration information, and the ones
chosen depend on the depth and/or fbbpp that is being used
for the screen, as well as the monitor number(s) in multi-
XFree86 Version 4.5.0 25
XF86Config(5) UNIX Programmer's Manual XF86Config(5)
monitor configurations. The Display subsection format is
described in the section below.
DISPLAY SUBSECTION
Each Screen section may have multiple Display subsections.
The "active" Display subsections are the first for each mon-
itor number that match the depth and/or fbbpp values being
used, or failing that, the first for each monitor number
that has neither a depth or fbbpp value specified. Display
subsections with no monitor number specified are used for
single monitor per screen configurations. The Display sub-
sections are optional. When there isn't one that matches
the monitor number and/or depth and/or fbbpp values being
used, all the parameters that can be specified here fall
back to their defaults.
Display subsections have the following format:
SubSection "Display"
Monitor monitor-num
Depth depth
entries
...
EndSubSection
None of the entries in a Display subsection are mandatory.
Monitor monitor-num
This entry specifies which Monitor entry of the
Screen section that this Display subsection applies
to. This number should match the monitor number of
one of the Monitor references in the Screen screen.
If it doesn't match, then this Display subsection
will be ignored. If this entry is omitted, it is
applied to single-monitor configurations. For
multi-monitor configurations, the driver may also use
information in this subsection for screen-wide param-
eters. Not all of the parameters in this subsection
make sense on a per-monitor basis. Which get used
and how they get used is currently up to the driver.
Entries that are relevant to multi-monitor configura-
tions include Modes, Virtual, ViewPort, and Options.
Depth depth
This entry specifies what colour depth the Display
subsection is to be used for. This entry is usually
specified, but it may be omitted to create a match-
all Display subsection or when wishing to match only
against the FbBpp parameter. The range of depth
values that are allowed depends on the driver. Most
driver support 8, 15, 16 and 24. Some also support 1
XFree86 Version 4.5.0 26
XF86Config(5) UNIX Programmer's Manual XF86Config(5)
and/or 4, and some may support other values (like
30). Note: depth means the number of bits in a pixel
that are actually used to determine the pixel colour.
32 is not a valid depth value. Most hardware that
uses 32 bits per pixel only uses 24 of them to hold
the colour information, which means that the colour
depth is 24, not 32.
FbBpp bpp
This entry specifies the framebuffer format this
Display subsection is to be used for. This entry is
only needed when providing depth 24 configurations
that allow a choice between a 24 bpp packed frame-
buffer format and a 32bpp sparse framebuffer format.
In most cases this entry should not be used.
Weight red-weight green-weight blue-weight
This optional entry specifies the relative RGB
weighting to be used for a screen is being used at
depth 16 for drivers that allow multiple formats.
This may also be specified from the command line with
the -weight option (see XFree86(1)).
Virtual xdim ydim
This optional entry specifies the virtual screen
resolution to be used. xdim must be a multiple of
either 8 or 16 for most drivers, and a multiple of 32
when running in monochrome mode. The given value
will be rounded down if this is not the case. Video
modes which are too large for the specified virtual
size will be rejected. If this entry is not present,
the virtual screen resolution will be set to accommo-
date all the valid video modes given in the Modes
entry. Some drivers/hardware combinations do not
support virtual screens. Refer to the appropriate
driver-specific documentation for details.
ViewPort x0 y0
This optional entry sets the upper left corner of the
initial display. This is only relevant when the vir-
tual screen resolution is different from the resolu-
tion of the initial video mode. If this entry is not
given, then the initial display will be centered in
the virtual display area.
Modes "mode-name" ...
This optional entry specifies the list of video modes
to use. Each mode-name specified must be in double
quotes. They must correspond to those specified or
referenced in the appropriate Monitor section
(including implicitly referenced built-in VESA stan-
dard modes). The server will delete modes from this
XFree86 Version 4.5.0 27
XF86Config(5) UNIX Programmer's Manual XF86Config(5)
list which don't satisfy various requirements. The
first valid mode in this list will be the default
display mode for startup. The list of valid modes is
converted internally into a circular list. It is
possible to switch to the next mode with
Ctrl+Alt+Keypad-Plus and to the previous mode with
Ctrl+Alt+Keypad-Minus. When this entry is omitted,
the valid modes referenced by the appropriate Monitor
section will be used. If the Monitor section con-
tains no modes, then the selection will be taken from
the built-in VESA standard modes.
Visual "visual-name"
This optional entry sets the default root visual
type. This may also be specified from the command
line (see the Xserver(1) man page). The visual types
available for depth 8 are (default is PseudoColor):
StaticGray
GrayScale
StaticColor
PseudoColor
TrueColor
DirectColor
The visual type available for the depths 15, 16 and
24 are (default is TrueColor):
TrueColor
DirectColor
Not all drivers support DirectColor at these depths.
The visual types available for the depth 4 are
(default is StaticColor):
StaticGray
GrayScale
StaticColor
PseudoColor
The visual type available for the depth 1 (mono-
chrome) is StaticGray.
Black red green blue
This optional entry allows the "black" colour to be
specified. This is only supported at depth 1. The
default is black.
White red green blue
This optional entry allows the "white" colour to be
specified. This is only supported at depth 1. The
XFree86 Version 4.5.0 28
XF86Config(5) UNIX Programmer's Manual XF86Config(5)
default is white.
Options
Option flags may be specified in the Display subsec-
tions. These may include driver-specific options and
driver-independent options. The former are described
in the driver-specific documentation. Some of the
latter are described above in the section about the
Screen section, and they may also be included here.
SERVERLAYOUT SECTION
The config file may have multiple ServerLayout sections. A
"server layout" represents the binding of one or more
screens (Screen sections) and one or more input devices
(InputDevice sections) to form a complete configuration. In
multi-head configurations, it also specifies the relative
layout of the heads. A ServerLayout section is considered
"active" if it is referenced by the -layout command line
option or by an Option "DefaultServerLayout" entry in the
ServerFlags section (the former takes precedence over the
latter). If those options are not used, the first Server-
Layout section found in the config file is considered the
active one. If no ServerLayout sections are present, the
single active screen and two active (core) input devices are
selected as described in the relevant sections above.
ServerLayout sections have the following format:
Section "ServerLayout"
Identifier "name"
Screen "screen-id"
...
InputDevice "idev-id"
...
options
...
EndSection
Each ServerLayout section must have an Identifier entry and
at least one Screen entry.
The Identifier entry specifies the unique name for this
server layout. The ServerLayout section provides informa-
tion specific to the whole session, including session-
specific Options. The ServerFlags options (described above)
may be specified here, and ones given here override those
given in the ServerFlags section.
The entries that may be used in this section are described
here.
Screen screen-num "screen-id" position-information
XFree86 Version 4.5.0 29
XF86Config(5) UNIX Programmer's Manual XF86Config(5)
One of these entries must be given for each screen
being used in a session. The screen-id field is man-
datory, and specifies the Screen section being refer-
enced. The screen-num field is optional, and may be
used to specify the screen number in multi-head con-
figurations. When this field is omitted, the screens
will be numbered in the order that they are listed
in. The numbering starts from 0, and must be consecu-
tive. The optional position-information field
describes the way multiple screens are positioned.
When this information is not provided, the position-
ing of the screen defaults to Absolute 0 0. There are
a number of different ways that this information can
be provided:
x y
Absolute x y
These both specify that the upper left corner's
coordinates are (x,y). The Absolute keyword is
optional. Some older versions of XFree86 (4.2
and earlier) don't recognise the Absolute key-
word, so it's safest to just specify the coordi-
nates without it.
RightOf "screen-id"
LeftOf "screen-id"
Above "screen-id"
Below "screen-id"
Relative "screen-id" x y
These give the screen's location relative to
another screen. The first four position the
screen immediately to the right, left, above or
below the other screen. When positioning to the
right or left, the top edges are aligned. When
positioning above or below, the left edges are
aligned. The Relative form specifies the offset
of the screen's origin (upper left corner) rela-
tive to the origin of another screen.
InputDevice "idev-id" "option" ...
One of these entries should be given for each input
device being used in a session. Normally at least
two are required, one each for the core pointer and
keyboard devices. If either of those is missing,
suitable InputDevice entries are searched for using
the method described above in the INPUTDEVICE sec-
tion. The idev-id field is mandatory, and specifies
XFree86 Version 4.5.0 30
XF86Config(5) UNIX Programmer's Manual XF86Config(5)
the name of the InputDevice section being referenced.
Multiple option fields may be specified, each in dou-
ble quotes. The options permitted here are any that
may also be given in the InputDevice sections. Nor-
mally only session-specific input device options
would be used here. The most commonly used options
are:
"CorePointer"
"CoreKeyboard"
"SendCoreEvents"
and the first two should normally be used to indicate
the core pointer and core keyboard devices respec-
tively.
Options
Any option permitted in the ServerFlags section may
