     This program is used to set various user preference options
     of the display.


     -display display
             This option specifies the server to use; see X(7).

     b       The b option controls bell volume, pitch and dura-
             tion. This option accepts up to three numerical
             parameters, a preceding dash(-), or a 'on/off' flag.
             If no parameters are given, or the 'on' flag is
             used, the system defaults will be used. If the dash
             or 'off' are given, the bell will be turned off. If
             only one numerical parameter is given, the bell
             volume will be set to that value, as a percentage of
             its maximum. Likewise, the second numerical parame-
             ter specifies the bell pitch, in hertz, and the
             third numerical parameter specifies the duration in
             milliseconds.  Note that not all hardware can vary
             the bell characteristics.  The X server will set the
             characteristics of the bell as closely as it can to
             the user's specifications.

     bc      The bc option controls bug compatibility mode in the
             server, if possible; a preceding dash(-) disables
             the mode, otherwise the mode is enabled.  Various
             pre-R4 clients pass illegal values in some protocol
             requests, and pre-R4 servers did not correctly gen-
             erate errors in these cases.  Such clients, when run
             against an R4 server, will terminate abnormally or
             otherwise fail to operate correctly. Bug compatibil-
             ity mode explicitly reintroduces certain bugs into
             the X server, so that many such clients can still be
             run.  This mode should be used with care; new appli-
             cation development should be done with this mode
             disabled.  The server must support the MIT-SUNDRY-

             NONSTANDARD protocol extension in order for this
             option to work.

     c       The c option controls key click. This option can
             take an optional value, a preceding dash(-), or an
             'on/off' flag. If no parameter or the 'on' flag is
             given, the system defaults will be used. If the dash
             or 'off' flag is used, keyclick will be disabled. If
             a value from 0 to 100 is given, it is used to indi-
             cate volume, as a percentage of the maximum. The X
             server will set the volume to the nearest value that
             the hardware can support.

     -dpms   The -dpms option disables DPMS (Energy Star)

     +dpms   The +dpms option enables DPMS (Energy Star)

     dpms flags...
             The dpms option allows the DPMS (Energy Star) param-
             eters to be set.  The option can take up to three
             numerical values, or the `force' flag followed by a
             DPMS state.  The `force' flags forces the server to
             immediately switch to the DPMS state specified.  The
             DPMS state can be one of `standby', `suspend',
             `off', or `on'.  When numerical values are given,
             they set the inactivity period (in units of seconds)
             before the three modes are activated. The first
             value given is for the `standby' mode, the second is
             for the `suspend' mode, and the third is for the
             `off' mode.  Setting these values implicitly enables
             the DPMS features.  A value of zero disables a par-
             ticular mode.

     fp= path,...
             The fp= sets the font path to the entries given in
             the path argument. The entries are interpreted by
             the server, not by the client. Typically they are
             directory names or font server names, but the
             interpretation is server-dependent.

     fp default
             The default argument causes the font path to be
             reset to the server's default.

     fp rehash
             The rehash argument resets the font path to its
             current value, causing the server to reread the font
             databases in the current font path.  This is gen-
             erally only used when adding new fonts to a font
             directory (after running mkfontdir to recreate the

             font database).

     -fp or fp-
             The -fp and fp- options remove elements from the
             current font path.  They must be followed by a
             comma-separated list of entries.

     +fp or fp+
             This +fp and fp+ options prepend and append elements
             to the current font path, respectively.  They must
             be followed by a comma-separated list of entries.

     led     The led option controls the keyboard LEDs. This con-
             trols the turning on or off of one or all of the
             LEDs. It accepts an optional integer, a preceding
             dash(-) or an 'on/off' flag. If no parameter or the
             'on' flag is given, all LEDs are turned on. If a
             preceding dash or the flag 'off' is given, all LEDs
             are turned off. If a value between 1 and 32 is
             given, that LED will be turned on or off depending
             on the existence of a preceding dash. A common LED
             which can be controlled is the ``Caps Lock'' LED.
             ``xset led 3'' would turn led #3 on.  ``xset -led
             3'' would turn it off. The particular LED values may
             refer to different LEDs on different hardware.

     m       The m option controls the mouse parameters. The
             parameters for the mouse are `acceleration' and
             `threshold'. The acceleration can be specified as an
             integer, or as a simple fraction. The mouse, or
             whatever pointer the machine is connected to, will
             go `acceleration' times as fast when it travels more
             than `threshold' pixels in a short time.  This way,
             the mouse can be used for precise alignment when it
             is moved slowly, yet it can be set to travel across
             the screen in a flick of the wrist when desired.
             One or both parameters for the m option can be omit-
             ted, but if only one is given, it will be inter-
             preted as the acceleration. If no parameters or the
             flag 'default' is used, the system defaults will be

     p       The p option controls pixel color values. The param-
             eters are the color map entry number in decimal, and
             a color specification.  The root background colors
             may be changed on some servers by altering the
             entries for BlackPixel and WhitePixel. Although
             these are often 0 and 1, they need not be.  Also, a
             server may choose to allocate those colors
             privately, in which case an error will be generated.
             The map entry must not be a read-only color, or an
             error will result.

     r       The r option controls the autorepeat. If a preceding
             dash or the 'off' flag is used, autorepeat will be
             disabled. If no parameters or the 'on' flag is used,
             autorepeat will be enabled. If a specific keycode is
             specified as a parameter, autorepeat for that key-
             code is enabled or disabled. If the server supports
             the XFree86-Misc extension, or the XKB extension,
             then a parameter of 'rate' is accepted and should be
             followed by zero, one or two numeric values. The
             first specifies the delay before autorepeat starts
             and the second specifies the repeat rate.  In the
             case that the server supports the XKB extension, the
             delay is the number of milliseconds before
             autorepeat starts, and the rate is the number of
             repeats per second.  If the rate or delay is not
             given, it will be set to the default value.

             Example: The following command will set the delay to
             200 milliseconds and the repeat rate to 10 per

                 xset r rate 200 10

     s       The s option lets you set the screen saver parame-
             ters. This option accepts up to two numerical param-
             eters, a 'blank/noblank' flag, an 'expose/noexpose'
             flag, an 'on/off' flag, an 'activate/reset' flag, or
             the 'default' flag. If no parameters or the
             'default' flag is used, the system will be set to
             its default screen saver characteristics. The
             'on/off' flags simply turn the screen saver func-
             tions on or off. The 'activate' flag forces activa-
             tion of screen saver even if the screen saver had
             been turned off. The 'reset' flag forces deactiva-
             tion of screen saver if it is active. The 'blank'
             flag sets the preference to blank the video (if the
             hardware can do so) rather than display a background
             pattern, while 'noblank' sets the preference to
             display a pattern rather than blank the video. The
             'expose' flag sets the preference to allow window
             exposures (the server can freely discard window con-
             tents), while 'noexpose' sets the preference to dis-
             able screen saver unless the server can regenerate
             the screens without causing exposure events. The
             length and period parameters for the screen saver
             function determines how long the server must be
             inactive for screen saving to activate, and the
             period to change the background pattern to avoid
             burn in. The arguments are specified in seconds. If
             only one numerical parameter is given, it will be
             used for the length.
