DESCRIPTION
nv is an XFree86 driver for NVIDIA video cards. The driver
supports 2D acceleration and provides support for the fol-
lowing framebuffer depths: 8, 15, 16 (except Riva128) and
24. All visual types are supported for depth 8, TrueColor
and DirectColor visuals are supported for the other depths
with the exception of the Riva128 which only supports
TrueColor in the higher depths.
SUPPORTED HARDWARE
The nv driver supports PCI and AGP video cards based on the
following NVIDIA chips:
RIVA 128 NV3
RIVA TNT NV4
RIVA TNT2 NV5
GeForce 256, QUADRO NV10
GeForce2, QUADRO2 NV11 & NV15
GeForce3, QUADRO DCC NV20
nForce, nForce2 NV1A, NV1F
GeForce4, QUADRO4 NV17, NV18, NV25, NV28
GeForce FX, QUADRO FX NV30, NV31, NV34, NV35, NV36, NV37,
NV38, NV40, NV41, NV43, NV44, NV45
CONFIGURATION DETAILS
Please refer to XF86Config(5) for general configuration
details. This section only covers configuration details
specific to this driver.
The driver auto-detects the chipset type and the amount of
video memory present for all chips.
XFree86 Version 4.5.0 1
NV(4) UNIX Programmer's Manual NV(4)
The following driver Options are supported:
Option "HWCursor" "boolean"
Enable or disable the HW cursor. Default: on.
Option "NoAccel" "boolean"
Disable or enable acceleration. Default: acceleration
is enabled.
Option "UseFBDev" "boolean"
Enable or disable use of on OS-specific fb interface
(and is not supported on all OSs). See fbdevhw(4) for
further information. Default: off.
Option "CrtcNumber" "integer"
GeForce2 MX, nForce2, Quadro4, GeForce4, Quadro FX and
GeForce FX may have two video outputs. The driver
attempts to autodetect which one the monitor is con-
nected to. In the case that autodetection picks the
wrong one, this option may be used to force usage of a
particular output. The options are "0" or "1". Default:
autodetected.
Option "FlatPanel" "boolean"
The driver usually can autodetect the presence of a
digital flat panel. In the case that this fails, this
option can be used to force the driver to treat the
attached device as a digital flat panel. With this
driver, a digital flat panel will only work if it was
POSTed by the BIOS, that is, the machine must have
booted to the panel. If you have a dual head card you
may also need to set the option CrtcNumber described
above. Default: off.
Option "FPDither" "boolean"
Many digital flat panels (particularly ones on laptops)
have only 6 bits per component color resolution. This
option tells the driver to dither from 8 bits per com-
ponent to 6 before the flat panel truncates it. This is
only supported in depth 24 on GeForce2 MX, nForce2,
GeForce4, Quadro4, Geforce FX and Quadro FX. Default:
off.
Option "FPScale" "boolean"
Supported only on GeForce4, Quadro4, Geforce FX and
Quadro FX. This option tells to the driver to scale
lower resolutions up to the flat panel's native resolu-
tion. Default: on.
Option "Rotate" "CW"
Option "Rotate" "CCW"
XFree86 Version 4.5.0 2
NV(4) UNIX Programmer's Manual NV(4)
Rotate the display clockwise or counterclockwise. This
mode is unaccelerated. Default: no rotation.
Note: The Resize and Rotate extension will be disabled
if the Rotate option is used.
Option "ShadowFB" "boolean"
Enable or disable use of the shadow framebuffer layer.
Default: off.
