NAME
nvidia-xconfig - manipulate X configuration files for the NVIDIA driver
SYNOPSIS
nvidia-xconfig [ options ]
DESCRIPTION
nvidia-xconfig is a tool intended to provide basic control over config‐
uration options available in the NVIDIA X driver.
nvidia-xconfig performs its operations in several steps:
1) The system X configuration file is found and read into memory.
If no configuration file can be found, nvidia-xconfig generates
one from scratch using default settings; in this case, nvidia-
xconfig will automatically determine the name of the X configu‐
ration file to create: /etc/X11/xorg.conf if the X server in use
is X.org or /etc/X11/XF86Config if the X server in use is
XFree86.
2) The configuration in memory is modified to support the NVIDIA
driver. This consists of changing the display driver to
"nvidia", removing the commands to load the "GLcore" and "dri"
modules, and adding the command to load the "glx" module.
3) The configuration in memory is modified according to the options
specified on the command line. Please see the NVIDIA README for
a description of the NVIDIA X configuration file options. Note
that nvidia-xconfig does not perform any validation of the X
configuration file options requested on the command line; X con‐
figuration file option validation is left for the NVIDIA X
driver.
4) The configuration is written back to the file from which it was
read. A backup of the original configuration is created with
".backup" appended. For example, if your X configuration is
/etc/X11/xorg.conf then nvidia-xconfig will copy it to
/etc/X11/xorg.conf.backup before writing the new configuration.
The --post-tree (-T) option can be used to print the new config‐
uration to standard out in tree form instead. This option is
useful to see what nvidia-xconfig will do while leaving the
original configuration intact.
OPTIONS
-c XCONFIG, --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=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 X configuration 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 configura‐
tion data in a tree , 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.
ADVANCED OPTIONS
--acpid-socket-path=ACPID-SOCKET-PATH, --no-acpid-socket-path
Set this option to specify an alternate path to the Linux ACPI
daemon (acpid)'s socket, which the NVIDIA X driver will use to
connect to acpid.
--add-argb-glx-visuals, --no-add-argb-glx-visuals
Enables or disables support for OpenGL rendering into 32-bit
ARGB windows and pixmaps.
--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.
--cool-bits=COOL-BITS, --no-cool-bits
Enable or disable the "Coolbits" X configuration option. Set‐
ting this option will enable support in the NV-CONTROL X exten‐
sion for manipulating GPU clock and GPU fan control settings.
Default value is 0. For fan control set it to 4. WARNING: this
may cause system damage and void warranties.
--composite, --no-composite
Enable or disable the "Composite" X extension.
--connected-monitor=CONNECTED-MONITOR, --no-connected-monitor
Enable or disable the "ConnectedMonitor" X configuration
option; setting this option forces the X driver to behave as if
the specified display devices are connected to the GPU.
--connect-to-acpid, --no-connect-to-acpid
Enable or disable the "ConnectToAcpid" X configuration option.
If this option is set, the NVIDIA X driver will attempt to con‐
nect to the Linux ACPI daemon (acpid). Set this option to off
to prevent the X driver from attempting to connect to acpid.
--constant-dpi, --no-constant-dpi
Enable or disable the "ConstantDPI" X configuration option,
which controls whether the NVIDIA X driver maintains a constant
dots per inch (DPI) value by recomputing the reported size in
millimeters of the X screen when XRandR changes the size in pix‐
els of the X screen.
--custom-edid=CUSTOM-EDID, --no-custom-edid
Enable or disable the "CustomEDID" X configuration option; set‐
ting this option forces the X driver to use the EDID speci‐
fied.This option is a semicolon-separated list of pairs of dis‐
play device names and filename pairs; e.g "CRT-0:mp\did.bin".
Note that a display device name must always be specified even if
only one EDID is specified.
--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).
-d DEPTH, --depth=DEPTH
Set the default depth to DEPTH ; valid values for DEPTH are 8,
15, 16, 24, and 30.
--disable-glx-root-clipping, --no-disable-glx-root-clipping
Disable or enable clipping OpenGL rendering to the root window
via the "DisableGLXRootClipping" X configuration option.
--damage-events, --no-damage-events
Use OS-level events to notify the X server when a direct-render‐
ing client has performed rendering that needs to be composited
to the screen. Improves performance when using GLX with the
composite extension.
--dynamic-twinview, --no-dynamic-twinview
Enable or disable support for dynamically configuring TwinView.
--preserve-driver-name
By default nvidia-xconfig changes the display driver to
"nvidia" for all configured X screens; this option preserves the
existing driver name of each X screen.
--enable-acpi-hotkeys, --no-enable-acpi-hotkeys
The "EnableACPIHotkeys" option can be specified to override the
NVIDIA X driver's default decision to enable or disable ACPI
display change hotkey events.
-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.
-E FILE, --extract-edids-from-file=FILE
Extract any raw EDID byte blocks contained in the specified X
log file LOG ; raw EDID bytes are printed by the NVIDIA X driver
to the X log as hexidecimal when verbose logging is enabled with
the "-logverbose 6" X server commandline option. Any extracted
EDIDs are then written as binary data to individual files.
These files can later be used by the NVIDIA X driver through the
"CustomEDID" X configuration option.
--extract-edids-output-file=FILENAME
When the '--extract-edids-from-log' option is used, nvidia-xcon‐
fig writes any extracted EDID to a file, typically "edid.bin" in
the current directory. Use this option to specify an alternate
filename. Note that nvidia-xconfig, if necessary, will append a
unique number to the EDID filename, to avoid overwriting exist‐
ing files (e.g., "edid.bin.1" if "edid.bin" already exists).
--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 draw‐
able is visible. This option forces stereo flipping even when no
stereo drawables are visible.
--handle-special-keys=WHEN, --no-handle-special-keys
Specify when the X server should use the builtin keyboard han‐
dler to process special key combinations (such as
Ctrl+Alt+Backspace); see the X configuration man page for
details. The value of WHEN can be 'Always', 'Never', or 'When‐
Needed'.
--include-implicit-metamodes, --no-include-implicit-metamodes
Enable or disable the "IncludeImplicitMetaModes" X configuration
option.
--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=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 lay‐
out 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.
--logo, --no-logo
Disable or enable the "NoLogo" X configuration option.
--logo-path=PATH, --no-logo-path
Set the path to the PNG file to be used as the logo splash
screen at X server startup.
--mode=MODE
Add the specified mode to the mode list.
--mode-debug, --no-mode-debug
Enable or disable the "ModeDebug" X configuration option; when
enabled, this option causes the X driver to print verbose
details about mode validation to the X log file.
--mode-list=MODELIST
Remove all existing modes from the X configuration's modelist
and add the one(s) specified in the MODELIST string.
--remove-mode=MODE
Remove 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.
--multigpu=MULTIGPU, --no-multigpu
Enable or disable MultiGPU. Valid values for MULTIGPU are
'Off', 'On', 'Auto', 'AFR', 'SFR', 'AA'.
--multisample-compatibility, --no-multisample-compatibility
Enable or disable the use of separate front and back multisample
buffers.
--nvagp=NVAGP, --no-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=PATH
The nvidia-cfg library is used to communicate with the NVIDIA
kernel module to query basic properties of every GPU in the sys‐
tem. This library is typically only used by nvidia-xconfig when
configuring multiple X screens. This option tells nvidia-xcon‐
fig 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.
--overlay-default-visual, --no-overlay-default-visual
Enable or disable the "OverlayDefaultVisual" X configuration
option.
--transparent-index=INDEX, --no-transparent-index
Pixel to use as transparent when using color index overlays.
Valid values for TRANSPARENT-INDEX are 0-255.
-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 .
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.
--probe-all-gpus, --no-probe-all-gpus
Disable or enable the "ProbeAllGpus" X configuration option.
--query-gpu-info
Print information about all recognized NVIDIA GPUs in the sys‐
tem.
--randr-rotation, --no-randr-rotation
Enable or disable the "RandRRotation" X configuration option.
--registry-dwords=REGISTRY-DWORDS, --no-registry-dwords
Enable or disable the "RegistryDwords" X configuration option.
--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.
--rotate=ROTATE, --no-rotate
Enable or disable the "Rotate" X configuration option. Valid
values for ROTATE are 'normal', 'left', 'CCW', 'inverted',
'right', and 'CW'. Rotation can be disabled
--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 configura‐
tion 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.
--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-sepa‐
rate-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, --no-sli
Enable or disable SLI. Valid values for SLI are 'Off', 'On',
'Auto', 'AFR', 'SFR', 'AA', 'AFRofAA'.
--stereo=STEREO, --no-stereo
Enable or disable the stereo mode. Valid values for STEREO are:
0 (Disabled), 1 (DDC glasses), 2 (Blueline glasses), 3 (Onboard
stereo), 4 (TwinView clone mode stereo), 5 (SeeReal digital flat
panel), 6 (Sharp3D digital flat panel), 7 (Arisawa/Hyundai/Zal‐
man/Pavione/Miracube), 8 (3D DLP), 9 (3D DLP INV), 10 (NVIDIA 3D
VISION).
--tv-standard=TV-STANDARD, --no-tv-standard
Enable or disable the "TVStandard" X configuration option. Valid
values for "TVStandard" are: "PAL-B", "PAL-D", "PAL-G", "PAL-H",
"PAL-I", "PAL-K1", "PAL-M", "PAL-N", "PAL-NC", "NTSC-J",
"NTSC-M", "HD480i", "HD480p", "HD720p", "HD1080i", "HD1080p",
"HD576i", "HD576p".
--tv-out-=TV-OUT-FORMAT, --no-tv-out-
Enable or disable the "TVOutFormat" X configuration option.
Valid values for "TVOutFormat" are: "SVIDEO" and "COMPOSITE".
--tv-over-scan=TV-OVER-SCAN, --no-tv-over-scan
Enable or disable the "TVOverScan" X configuration option. Valid
values are decimal values in the range 1.0 and 0.0.
--twinview, --no-twinview
Enable or disable TwinView.
--twinview-orientation=ORIENTATION, --no-twinview-orientation
Specify the TwinViewOrientation. Valid values for ORIENTATION
are: "RightOf" (the default), "LeftOf", "Above", "Below", or
"Clone".
--twinview-xinerama-info, --no-twinview-xinerama-info
Prohibits providing Xinerama information when in TwinView.
--twinview-xinerama-info-order=TWINVIEW-XINERAMA-INFO-ORDER, --no-twin‐
view-xinerama-info-order
Enable or disable the "TwinViewXineramaInfoOrder" X configura‐
tion option. TWINVIEW-XINERAMA-INFO-ORDER is a comma-separated
list of display device names that describe the order in which
TwinViewXineramaInfo should be reported. E.g., "CRT, DFP, TV".
--ubb, --no-ubb
Enable or disable the "UBB" X configuration option.
--use-edid, --no-use-edid
Enable or disable use of the EDID (Extended Display Identifica‐
tion Data) from your display device(s). The EDID will be used
for driver operations such as building lists of available modes,
determining valid frequency ranges, and computing the DPI (Dots
Per Inch). This option defaults to TRUE (the NVIDIA X driver
will use the EDID, when available). It is NOT recommended that
you use this option to globally disable use of the EDID;
instead, use '--no-use-edid-freqs' or '--no-use-edid-dpi' to
disable specific uses of the EDID.
--use-edid-dpi, --no-use-edid-dpi
Enable or disable use of the physical size information in the
display device's EDID, if any, to compute the DPI (Dots Per
Inch) of the X screen. This option defaults to TRUE (the NVIDIA
X driver uses the EDID's physical size, when available, to com‐
pute the DPI).
--use-edid-freqs, --no-use-edid-freqs
Enable or disable use of 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. This option defaults to TRUE
(the NVIDIA X driver will use frequency information from the
EDID, when available).
--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.
--use-display-device=DISPLAY-DEVICE, --no-use-display-device
Force the X driver to use the display device specified.
--use-events, --no-use-events
Enable or disable "UseEvents" X configuration option. Setting
this option will enable the X driver to use the system events in
some cases when it is waiting for the hardware. With this option
X driver sets an event handler and waits for the hardware
through the poll() system call. This option defaults to FALSE.
--virtual=WIDTHxHEIGHT, --no-virtual
Specify the virtual screen resolution.
--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.
EXAMPLES
nvidia-xconfig
Reads an existing X config file and adapts it to use the NVIDIA
driver. If no X config file can be found, a new one is created
at /etc/X11/XF86Config with default settings.
nvidia-xconfig --post-tree --twinview
Reads the existing X configuration file, adds the TwinView
option, and then prints the resulting config file to standard
out in tree form. The configuration file is not modified.
nvidia-xconfig --enable-all-gpus
Examines the system and configures an X screen for each display
device it finds.
nvidia-xconfig --mode=1600x1200
Adds a 1600x1200 mode to an existing X configuration.
nvidia-xconfig --mode-list=1600x1200 1280x1024
Removes any existing modes from the X configuration file,
replacing them with "1600x1200" and "1280x1024".
nvidia-xconfig --only-one-x-screen --sli=Auto
Configures the X server to have just one X screen that will use
SLI when available.
