The NVIDIA X Configuration Tool.
This program is used to manipulate X configuration files, specifically to
enable NVIDIA X driver functionality.
Copyright (C) 2005 NVIDIA Corporation.
In its normal operation, nvidia-xconfig finds the system X configuration file
(or generates a new X configuration if it cannot find the system file), makes
sure the configuration is usable by the NVIDIA X driver, applies any updates
requested on the commandline, and writes the new configuration to file.
Please see the NVIDIA README for a description of NVIDIA X configuration file
options.
nvidia-xconfig [options]
-c, --xconfig=XCONFIG
Use XCONFIG as the input X config file; if this option is not specified,
then the same search path used by the X server will be used to find the X
configuration file.
-o, --output-xconfig=OUTPUT-XCONFIG
Use OUTPUT-XCONFIG as the output X configuration file; if this option is
not specified, then the input X configuration filename will also be used
as the output filename.
-s, --silent
Run silently; no messages will be printed to stdout, except for warning
and error messages to stderr.
-t, --tree
Read the X configuration file, print to stdout the X configuration data
in a tree format, and exit.
-v, --version
Print the nvidia-xconfig version and exit.
-h, --help
Print usage information for the common commandline options and exit.
-A, --advanced-help
Print usage information for the common commandline options as well as the
advanced options, and then exit.
--add-argb-glx-visuals/--no-add-argb-glx-visuals
Enables or disables support for OpenGL rendering into 32-bit ARGB windows
and pixmaps.
--allow-ddcci/--no-allow-ddcci
Enables or disables DDC/CI support in the NV-CONTROL X extension.
--allow-dfp-stereo/--no-allow-dfp-stereo
Enable or disable the "AllowDFPStereo" X configuration option.
--allow-glx-with-composite/--no-allow-glx-with-composite
Enable or disable the "AllowGLXWithComposite" X configuration option.
--bandwidth-test/--no-bandwidth-test
Disable or enable the "NoBandWidthTest" X configuration option.
--composite/--no-composite
Enable or disable the "Composite" X extension.
--dac-8bit/--no-dac-8bit
Most Quadro parts by default use a 10 bit color look up table (LUT) by
default; setting this option to TRUE forces these graphics chips to use
an 8 bit (LUT).
--ddc/--no-ddc
Synonym for "ignore-edid"
-d, --depth=DEPTH
Set the default depth to DEPTH; valid values for DEPTH are 8, 15, 16 and
24.
--digital-vibrance=DIGITAL-VIBRANCE/--no-digital-vibrance
Enables digital vibrance control. Valid values for DIGITAL-VIBRANCE are
0-255.
-a, --enable-all-gpus
Configure an X screen on every GPU in the system.
--exact-mode-timings-dvi/--no-exact-mode-timings-dvi
Forces the initialization of the X server with the exact timings
specified in the ModeLine.
--flip/--no-flip
Enable or disable OpenGL flipping
--force-generate
Force generation of a new X config file, ignoring any existing system X
config file. This is not typically recommended, as things like the mouse
protocol, keyboard layout, font paths, etc, are setup by your Unix
distribution. While nvidia-xconfig can attempt to infer these values, it
is best to use your Unix distribution's X config file for the basis of
anything that nvidia-xconfig creates.
--force-stereo-flipping/--no-force-stereo-flipping
Normally, stereo flipping is only performed when a stereo drawable is
visible. This option forces stereo flipping even when no stereo drawables
are visible.
--ignore-edid/--no-ignore-edid
Disable or enable probing of EDID (Extended Display Identification Data)
from your monitor.
--use-edid-freqs/--no-use-edid-freqs
Allow or disallow the X server to use the HorizSync and VertRefresh
ranges given in a display device's EDID, if any. EDID provided range
information will override the HorizSync and VertRefresh ranges specified
in the Monitor section.
--keyboard=KEYBOARD
When generating a new X configuration file (which happens when no system
X configuration file can be found, or the '--force-generate' option is
specified), use KEYBOARD as the keyboard type, rather than attempting to
probe the system for the keyboard type. For a list of possible keyboard
types, see the '--keyboard-list' option.
--keyboard-driver=KEYBOARD-DRIVER
In most cases nvidia-xconfig can automatically determine the correct
keyboard driver to use (either 'kbd' or 'keyboard'). Use this option to
override what nvidia-xconfig detects. Typically, if you are using an
X.org X server, use 'kdb'; if you are using an XFree86 X server, use
'keyboard'.
--keyboard-list
Print to stdout the available keyboard types recognized by the
'--keyboard' option, and then exit.
--layout=LAYOUT
The nvidia-xconfig utility operates on a Server Layout within the X
configuration file. If this option is specified, the layout named LAYOUT
in the X configuration file will be used. If this option is not
specified, the first Server Layout in the X configuration file is used.
--screen=SCREEN
The nvidia-xconfig utility operates on one or more screens within a
Server Layout in the X configuration file. If this option is specified,
the screen named SCREEN in the X configuration file will be used. If
this option is not specified, all screens within the selected Server
Layout in the X configuration file will be used used.
--load-kernel-module/--no-load-kernel-module
Allow or disallow NVIDIA Linux X driver module to load the NVIDIA Linux
kernel module automatically.
--logo/--no-logo
Disable or enable the "NoLogo" X configuration option.
--mode=MODE/--no-mode
Adds or removes the specified mode from the mode list.
--mouse=MOUSE
When generating a new X configuration file (which happens when no system
X configuration file can be found, or the '--force-generate' option is
specified), use MOUSE as the mouse type, rather than attempting to probe
the system for the mouse type. For a list of possible mouse types, see
the '--mouse-list' option.
--mouse-list
Print to stdout the available mouse types recognized by the '--mouse'
option, and then exit.
--multisample-compatibility/--no-multisample-compatibility
Enable or disable the use of separate front and back multisample
buffers.
--nvagp=NVAGP
Set the NvAGP X config option value. Possible values are 0 (no AGP), 1
(NVIDIA's AGP), 2 (AGPGART), 3 (try AGPGART, then try NVIDIA's AGP);
these values can also be specified as 'none', 'nvagp', 'agpgart', or
'any'.
--nvidia-cfg-path=NVIDIA-CFG-PATH
The nvidia-cfg library is used to communicate with the NVIDIA kernel
module to query basic properties of every GPU in the system. This
library is typically only used by nvidia-xconfig when configuring
multiple X screens. This option tells nvidia-xconfig where to look for
this library (in case it cannot find it on its own). This option should
normally not be needed.
--only-one-x-screen
Disable all but one X screen.
--overlay/--no-overlay
Enable or disable the "Overlay" X configuration option.
--cioverlay/--no-cioverlay
Enable or disable the color index overlay.
--transparent-index=TRANSPARENT-INDEX/--no-transparent-index
Pixel to use as transparent when using color index overlays. Valid
values for TRANSPARENT-INDEX are 0-255.
--overlay-default-visual/--no-overlay-default-visual
Enable or disable the "OverlayDefaultVisual" X configuration option.
-T, --post-tree
Like the '--tree' option, but goes through the full process of applying
any user requested updates to the X configuration, before printing the
final configuration to stdout in a tree format. Effectively, this option
just causes the configuration to be printed to stdout as a tree instead
of writing the results to file.
--power-connector-check/--no-power-connector-check
Disable or enable the "NoPowerConnectorCheck" X configuration option.
--query-gpu-info
Print information about all recognized NVIDIA GPUs in the system.
--randr-rotation/--no-randr-rotation
Enable or disable the "RandRRotation" X configuration option.
--rotate=ROTATE
Enable or disable the "Rotate" X configuration option. Valid values for
ROTATE are 'normal', 'left', 'inverted', and 'right'.
--render-accel/--no-render-accel
Enable or disable the "RenderAccel" X configuration option.
--render-extension/--no-render-extension
Disable or enable the "NoRenderExtension" X configuration option.
--separate-x-screens/--no-separate-x-screens
A GPU that supports multiple simultaneous display devices can either
drive these display devices in TwinView, or as separate X screens. When
the '--separate-x-screens' option is specified, each GPU on which an X
screen is currently configured will be updated to have two X screens
configured. The '--no-separate-x-screens' option will remove the second
configured X screen on each GPU. Please see the NVIDIA README
description of "Separate X Screens on One GPU" for further details.
--sli=SLI
Enable or disable SLI. Valid values for SLI are 'Off', 'Auto', 'AFR',
'SFR', and 'SLIAA'.
--stereo=STEREO/--no-stereo
Enable/Disable the stereo mode. Valid values for STEREO are: 1 (DCC
glasses), 2 (Blueline glasses), 3 (Onboard stereo), 4 (TwinView clone
mode stereo), 5 (SeeReal digital flat panel), 6 (Sharp3D digital flat
panel).
--twinview/--no-twinview
Enable or disable TwinView.
--twinview-xinerama-info/--no-twinview-xinerama-info
Prohibits providing Xinerama information when in TwinView.
--ubb/--no-ubb
Enable or disable the "UBB" X configuration option.
--use-int10-module/--no-use-int10-module
Enable use of the X Int10 module to soft-boot all secondary cards, rather
than POSTing the cards through the NVIDIA kernel module.
--x-prefix=X-PREFIX
The X installation prefix; the default is /usr/X11R6/. Only under rare
circumstances should this option be needed.
--xinerama/--no-xinerama
Enable or disable Xinerama.
--xvmc-uses-textures/--no-xvmc-uses-textures
Forces XvMC to use the 3D engine for XvMCPutSurface requests rather than
the video overlay.
