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 configuration 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 configuration 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 configuration 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 configuration to standard out in tree form instead. This option is useful to see what nvidia-xconfig will do while leaving the original configuration intact.

The source code to nvidia-xconfig is released under the GPL and available here:

Patches are welcome.

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 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.

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.

--busid=BUSID, --no-busid

This option writes the specified BusID to the device section of the X configuration file. If there are multiple device sections, then it adds the BusID field to each of them. To add the BusID to only a specific device or screen section, use the '--device' or '--screen' options.

--preserve-busid, --no-preserve-busid

By default, nvidia-xconfig preserves the existing BusID in the X configuration file only if there are multiple X screens configured for the X server. Use '--preserve-busid' or '--no-preserve-busid' to force the BusID to be preserved or not preserved, overriding the default behavior.

--cool-bits=COOL-BITS, --no-cool-bits

Enable or disable the "Coolbits" X configuration option. Setting this option will enable support in the NV-CONTROL X extension 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 connect 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 pixels of the X screen.

--custom-edid=CUSTOM-EDID, --no-custom-edid

Enable or disable the "CustomEDID" X configuration option; setting this option forces the X driver to use the EDID specified.This option is a semicolon-separated list of pairs of display 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.

--device=DEVICE

The nvidia-xconfig utility operates on one or more devices in the X configuration file. If this option is specified, the device named DEVICE in the X configuration file will be used. If this option is not specified, all the devices within the X configuration file will be used.

--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-rendering 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-file' option is used, nvidia-xconfig 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 existing files (e.g., "edid.bin.1" if "edid.bin" already exists).

--flatpanel-properties=FLATPANEL-PROPERTIES, --no-flatpanel-properties

Set the flat panel properties. The supported properties are 'dithering' and 'ditheringmode'. Please see the NVIDIA README 'Appendix B. X Config Options' for more details on the possible values and syntax.

--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.

--handle-special-keys=WHEN, --no-handle-special-keys

Specify when the X server should use the builtin keyboard handler 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 'WhenNeeded'.

--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 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.

--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.

--metamodes=METAMODES

Add the MetaMode X configuration option with the value METAMODES which will replace any existing MetaMode option already in the X configuration file.

--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 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.

--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 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.

--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 system.

--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 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.

--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, --no-sli

Enable or disable SLI. Valid values for SLI are 'Off', 'On', 'Auto', 'AFR', 'SFR', 'AA', 'AFRofAA', 'Mosaic'.

--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 (multi-display clone mode stereo), 5 (SeeReal digital flat panel), 6 (Sharp3D digital flat panel), 7 (Arisawa/Hyundai/Zalman/Pavione/Miracube), 8 (3D DLP), 9 (3D DLP INV), 10 (NVIDIA 3D VISION), 11 (NVIDIA 3D VISION PRO).

--thermal-configuration-check, --no-thermal-configuration-check

Disable or enable the "ThermalConfigurationCheck" X configuration option.

--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-format=TV-OUT-FORMAT, --no-tv-out-format

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.

--metamode-orientation=ORIENTATION, --no-metamode-orientation

Specify the MetaModeOrientation. Valid values for ORIENTATION are: "RightOf" (the default), "LeftOf", "Above", "Below", or "Clone".

--nvidia-xinerama-info, --no-nvidia-xinerama-info

Enable or disable providing Xinerama information from the NVIDIA X driver.

--nvidia-xinerama-info-order=NVIDIA-XINERAMA-INFO-ORDER, --no-nvidia-xinerama-info-order

Enable or disable the "nvidiaXineramaInfoOrder" X configuration option. NVIDIA-XINERAMA-INFO-ORDER is a comma-separated list of display device names that describe the order in which nvidiaXineramaInfo 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 Identification 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 compute 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.

--color-space=COLORSPACE, --no-color-space

Enable or disable the "ColorSpace" X configuration option. Valid values for "COLORSPACE" are: "RGB" and "YCbCr444".

--color-range=COLORRANGE, --no-color-range

Sets the "ColorRange" X configuration option. Valid values for "COLORRANGE" are: "Full" and "Limited".

--3dvision-usb-path=3DVISION-USB-PATH

Set this option to specify the sysfs path of the connected USB dongle.

--3dvisionpro-config-file=3DVISIONPRO-CONFIG-FILE

Set this option to specify the NVIDIA 3DVisionPro configuration file. Ensure X server has a read and write access permissions to this file. NVIDIA X driver stores the hub and the pairing configuration in this file to re-use across X restarts. If this option is not provided, 3D VisionPro configuration will not be stored.

--3dvision-display-type=3DVISION-DISPLAY-TYPE, --no-3dvision-display-type

When NVIDIA 3D Vision is enabled with a non 3D Vision ready display, use this option to specify the display type. Valid values are: 0 (Assume it is a CRT), 1 (Assume it is a DLP) and 2 (Assume it is a DLP TV and enable the checkerboard output).

--base-mosaic, --no-base-mosaic

Enable or disable the "BaseMosaic" X configuration option.

--restore-original-backup

Restore a backup of the X configuration that was made before any changes were made by nvidia-xconfig, if such a backup is available. This type of backup is made by nvidia-xconfig before it modifies an X configuration file that it has not previously touched; this is assumed to be an X configuration file that predates the involvement of the NVIDIA X driver. As an example, nvidia-xconfig will copy an X configuration file at /etc/X11/xorg.conf to /etc/X11/xorg.conf.nvidia-xconfig-original the first time it makes changes to that file.

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 --metamode-orientation=clone

Reads the existing X configuration file, adds the MetaModeOrientation 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 --metamodes=1024x768 +0+0, 1024x768 +1024+0

Adds the MetaMode "1024x768 +0+0, 1024x768 +1024+0" to the existing X configuration file, replacing any existing MetaModes X configuration option.

nvidia-xconfig --only-one-x-screen --sli=Auto

Configures the X server to have just one X screen that will use SLI when available.
