It now runs +on a wider range of hardware and OS platforms. +.PP +This work was derived from +.I "XFree86\ 4.4rc2" +by the X.Org Foundation. +The XFree86 4.4rc2 release was originally derived from +.I "X386\ 1.2" +by Thomas Roell which was contributed to X11R5 by Snitily Graphics +Consulting Service. The +.B __xservername__ +server architecture includes +among many other things a loadable module system derived from code +donated by Metro Link, Inc. The current __xservername__ release is compatible +with X11R6.6. +.SH PLATFORMS +.PP +.B __xservername__ +operates under a wide range of operating systems and hardware platforms. +The Intel x86 (IA32) architecture is the most widely supported hardware +platform. Other hardware platforms include Compaq Alpha, Intel IA64, +SPARC and PowerPC. The most widely supported operating systems are the +free/OpenSource UNIX-like systems such as Linux, FreeBSD, NetBSD and +OpenBSD. Commercial UNIX operating systems such as Solaris (x86) and +UnixWare are also supported. Other supported operating systems include +LynxOS, and GNU Hurd. Darwin and Mac OS X are supported with the +XDarwin(1) X server. Win32/Cygwin is supported with the XWin X server. +.PP +.SH "NETWORK CONNECTIONS" +.B __xservername__ +supports connections made using the following reliable +byte-streams: +.TP 4 +.I "Local" +On most platforms, the "Local" connection type is a UNIX-domain socket. +On some System V platforms, the "local" connection types also include +STREAMS pipes, named pipes, and some other mechanisms. +.TP 4 +.I TCP\/IP +.B __xservername__ +listens on port +.RI 6000+ n , +where +.I n +is the display number. This connection type can be disabled with the +.B \-nolisten +option (see the Xserver(1) man page for details). +.SH "ENVIRONMENT VARIABLES" +For operating systems that support local connections other than Unix +Domain sockets (SVR3 and SVR4), there is a compiled-in list specifying +the order in which local connections should be attempted. This list +can be overridden by the +.I XLOCAL +environment variable described below. If the display name indicates a +best-choice connection should be made (e.g. +.BR :0.0 ), +each connection mechanism is tried until a connection succeeds or no +more mechanisms are available. Note: for these OSs, the Unix Domain +socket connection is treated differently from the other local connection +types. To use it the connection must be made to +.BR unix:0.0 . +.PP +The +.I XLOCAL +environment variable should contain a list of one more +more of the following: +.PP +.RS 8 +.nf +NAMED +PTS +SCO +ISC +.fi +.RE +.PP +which represent SVR4 Named Streams pipe, Old-style USL Streams pipe, +SCO XSight Streams pipe, and ISC Streams pipe, respectively. You can +select a single mechanism (e.g. +.IR XLOCAL=NAMED ), +or an ordered list (e.g. \fIXLOCAL="NAMED:PTS:SCO"\fP). +his variable overrides the compiled-in defaults. For SVR4 it is +recommended that +.I NAMED +be the first preference connection. The default setting is +.IR PTS:NAMED:ISC:SCO . +.PP +To globally override the compiled-in defaults, you should define (and +export if using +.B sh +or +.BR ksh ) +.I XLOCAL +globally. If you use startx(1) or xinit(1), the definition should be +at the top of your +.I .xinitrc +file. If you use xdm(1), the definitions should be early on in the +.I __projectroot__/lib/X11/xdm/Xsession +script. +.SH OPTIONS +.B __xservername__ +supports several mechanisms for supplying/obtaining configuration and +run-time parameters: command line options, environment variables, the +__xconfigfile__(__filemansuffix__) configuration file, auto-detection, and +fallback defaults. When the same information is supplied in more than +one way, the highest precedence mechanism is used. The list of mechanisms +is ordered from highest precedence to lowest. Note that not all parameters +can be supplied via all methods. The available command line options +and environment variables (and some defaults) are described here and in +the Xserver(1) manual page. Most configuration file parameters, with +their defaults, are described in the __xconfigfile__(__filemansuffix__) manual +page. Driver and module specific configuration parameters are described +in the relevant driver or module manual page. +.PP +In addition to the normal server options described in the Xserver(1) +manual page, +.B __xservername__ +accepts the following command line switches: +.TP 8 +.BI vt XX +.I XX +specifies the Virtual Terminal device number which +.B __xservername__ +will use. Without this option, +.B __xservername__ +will pick the first available Virtual Terminal that it can locate. This +option applies only to platforms such as Linux, BSD, SVR3 and SVR4, that +have virtual terminal support. +.TP +.B \-allowMouseOpenFail +Allow the server to start up even if the mouse device can't be opened +or initialised. This is equivalent to the +.B AllowMouseOpenFail +__xconfigfile__(__filemansuffix__) file option. +.TP 8 +.B \-allowNonLocalModInDev +Allow changes to keyboard and mouse settings from non-local clients. +By default, connections from non-local clients are not allowed to do +this. This is equivalent to the +.B AllowNonLocalModInDev +__xconfigfile__(__filemansuffix__) file option. +.TP 8 +.B \-allowNonLocalXvidtune +Make the VidMode extension available to remote clients. This allows +the xvidtune client to connect from another host. This is equivalent +to the +.B AllowNonLocalXvidtune +__xconfigfile__(__filemansuffix__) file option. By default non-local +connections are not allowed. +.TP 8 +.BI \-bgamma " value" +Set the blue gamma correction. +.I value +must be between 0.1 and 10. +The default is 1.0. Not all drivers support this. See also the +.BR \-gamma , +.BR \-rgamma , +and +.B \-ggamma +options. +.TP 8 +.BI \-bpp " n" +No longer supported. Use +.B \-depth +to set the color depth, and use +.B \-fbbpp +if you really need to force a non-default framebuffer (hardware) pixel +format. +.TP +.B \-configure +When this option is specified, the +.B __xservername__ +server loads all video driver modules, probes for available hardware, +and writes out an initial __xconfigfile__(__filemansuffix__) file based on +what was detected. This option currently has some problems on some +platforms, but in most cases it is a good way to bootstrap the +configuration process. This option is only available when the server +is run as root (i.e, with real-uid 0). +.TP 8 +.BI "\-crt /dev/tty" XX +SCO only. This is the same as the +.B vt +option, and is provided for compatibility with the native SCO X server. +.TP 8 +.BI \-depth " n" +Sets the default color depth. Legal values are 1, 4, 8, 15, 16, and +24. Not all drivers support all values. +.TP 8 +.B \-disableModInDev +Disable dynamic modification of input device settings. This is equivalent +to the +.B DisableModInDev +__xconfigfile__(__filemansuffix__) file option. +.TP 8 +.B \-disableVidMode +Disable the the parts of the VidMode extension (used by the xvidtune +client) that can be used to change the video modes. This is equivalent +to the +.B DisableVidModeExtension +__xconfigfile__(__filemansuffix__) file option. +.TP 8 +.B \-fbbpp \fIn\fP +Sets the number of framebuffer bits per pixel. You should only set this +if you're sure it's necessary; normally the server can deduce the correct +value from +.B \-depth +above. Useful if you want to run a depth 24 configuration with a 24 +bpp framebuffer rather than the (possibly default) 32 bpp framebuffer +(or vice versa). Legal values are 1, 8, 16, 24, 32. Not all drivers +support all values. +.TP 8 +.B \-flipPixels +Swap the default values for the black and white pixels. +.TP 8 +.BI \-gamma " value" +Set the gamma correction. +.I value +must be between 0.1 and 10. The default is 1.0. This value is applied +equally to the R, G and B values. Those values can be set independently +with the +.BR \-rgamma , +.BR \-bgamma , +and +.B \-ggamma +options. Not all drivers support this. +.TP 8 +.BI \-ggamma " value" +Set the green gamma correction. +.I value +must be between 0.1 and 10. The default is 1.0. Not all drivers support +this. See also the +.BR \-gamma , +.BR \-rgamma , +and +.B \-bgamma +options. +.TP 8 +.B \-ignoreABI +The +.B __xservername__ +server checks the ABI revision levels of each module that it loads. It +will normally refuse to load modules with ABI revisions that are newer +than the server's. This is because such modules might use interfaces +that the server does not have. When this option is specified, mismatches +like this are downgraded from fatal errors to warnings. This option +should be used with care. +.TP 8 +.B \-keeptty +Prevent the server from detaching its initial controlling terminal. +This option is only useful when debugging the server. Not all platforms +support (or can use) this option. +.TP 8 +.BI \-keyboard " keyboard-name" +Use the __xconfigfile__(__filemansuffix__) file +.B InputDevice +section called +.I keyboard-name +as the core keyboard. This option is ignored when the +.B Layout +section specifies a core keyboard. In the absence of both a Layout +section and this option, the first relevant +.B InputDevice +section is used for the core keyboard. +.TP 8 +.BI \-layout " layout-name" +Use the __xconfigfile__(__filemansuffix__) file +.B Layout +section called +.IR layout-name . +By default the first +.B Layout +section is used. +.TP 8 +.BI \-logfile " filename" +Use the file called +.I filename +as the +.B __xservername__ +server log file. The default log file is +.BI __logdir__/__xservername__. n .log +on most platforms, where +.I n +is the display number of the +.B __xservername__ +server. The default may be in a different directory on some platforms. +This option is only available when the server is run as root (i.e, with +real-uid 0). +.TP 8 +.BR \-logverbose " [\fIn\fP]" +Sets the verbosity level for information printed to the +.B __xservername__ +server log file. If the +.I n +value isn't supplied, each occurrence of this option increments the log +file verbosity level. When the +.I n +value is supplied, the log file verbosity level is set to that value. +The default log file verbosity level is 3. +.TP 8 +.BI \-modulepath " searchpath" +Set the module search path to +.IR searchpath . +.I searchpath +is a comma separated list of directories to search for +.B __xservername__ +server modules. This option is only available when the server is run +as root (i.e, with real-uid 0). +.TP 8 +.B \-nosilk +Disable Silken Mouse support. +.TP 8 +.B \-pixmap24 +Set the internal pixmap format for depth 24 pixmaps to 24 bits per pixel. +The default is usually 32 bits per pixel. There is normally little +reason to use this option. Some client applications don't like this +pixmap format, even though it is a perfectly legal format. This is +equivalent to the +.B Pixmap +__xconfigfile__(__filemansuffix__) file option. +.TP 8 +.B \-pixmap32 +Set the internal pixmap format for depth 24 pixmaps to 32 bits per pixel. +This is usually the default. This is equivalent to the +.B Pixmap +__xconfigfile__(__filemansuffix__) file option. +.TP 8 +.BI \-pointer " pointer-name" +Use the __xconfigfile__(__filemansuffix__) file +.B InputDevice +section called +.I pointer-name +as the core pointer. This option is ignored when the +.B Layout +section specifies a core pointer. In the absence of both a Layout +section and this option, the first relevant +.B InputDevice +section is used for the core pointer. +.TP 8 +.B \-probeonly +Causes the server to exit after the device probing stage. The +__xconfigfile__(__filemansuffix__) file is still used when this option is +given, so information that can be auto-detected should be commented out. +.TP 8 +.B \-quiet +Suppress most informational messages at startup. The verbosity level +is set to zero. +.TP 8 +.BI \-rgamma " value" +Set the red gamma correction. +.I value +must be between 0.1 and 10. The default is 1.0. Not all drivers support +this. See also the +.BR \-gamma , +.BR \-bgamma , +and +.B \-ggamma +options. +.TP 8 +.B \-scanpci +When this option is specified, the +.B __xservername__ +server scans the PCI bus, and prints out some information about each +device that was detected. See also scanpci(1) and pcitweak(1). +.TP 8 +.BI \-screen " screen-name" +Use the __xconfigfile__(__filemansuffix__) file +.B Screen +section called +.IR screen-name . +By default the screens referenced by the default +.B Layout +section are used, or the first +.B Screen +section when there are no +.B Layout +sections. +.TP 8 +.B \-showconfig +This is the same as the +.B \-version +option, and is included for compatibility reasons. It may be removed +in a future release, so the +.B \-version +option should be used instead. +.TP 8 +.BI \-weight " nnn" +Set RGB weighting at 16 bpp. The default is 565. This applies only to +those drivers which support 16 bpp. +.TP 8 +.BR \-verbose " [\fIn\fP]" +Sets the verbosity level for information printed on stderr. If the +.I n +value isn't supplied, each occurrence of this option increments the +verbosity level. When the +.I n +value is supplied, the verbosity level is set to that value. The default +verbosity level is 0. +.TP 8 +.B \-version +Print out the server version, patchlevel, release date, the operating +system/platform it was built on, and whether it includes module loader +support. +.TP 8 +.BI \-config " file" +Read the server configuration from +.IR file . +This option will work for any file when the server is run as root (i.e, +with real-uid 0), or for files relative to a directory in the config +search path for all other users. +.SH "KEYBOARD" +.PP +The +.B __xservername__ +server is normally configured to recognize various special combinations +of key presses that instruct the server to perform some action, rather +than just sending the key press event to a client application. The +default XKEYBOARD keymap defines the key combinations listed below. +The server also has these key combinations builtin to its event handler +for cases where the XKEYBOARD extension is not being used. When using +the XKEYBOARD extension, which key combinations perform which actions +is completely configurable. +.PP +For more information about when the builtin event handler +is used to recognize the special key combinations, see +the documentation on the +.B HandleSpecialKeys +option in the __xconfigfile__(__filemansuffix__) man page. +.PP +The special combinations of key presses recognized directly +by +.B __xservername__ +are: +.TP 8 +.B Ctrl+Alt+Backspace +Immediately kills the server -- no questions asked. This can be disabled +with the +.B DontZap +__xconfigfile__(__filemansuffix__) file option. +.TP 8 +.B Ctrl+Alt+Keypad-Plus +Change video mode to next one specified in the configuration file. +This can be disabled with the +.B DontZoom +__xconfigfile__(__filemansuffix__) file option. +.TP 8 +.B Ctrl+Alt+Keypad-Minus +Change video mode to previous one specified in the configuration file. +This can be disabled with the +.B DontZoom +__xconfigfile__(__filemansuffix__) file option. +.TP 8 +.B Ctrl+Alt+Keypad-Multiply +Not treated specially by default. If the +.B AllowClosedownGrabs +__xconfigfile__(__filemansuffix__) file option is specified, this key sequence +kills clients with an active keyboard or mouse grab as well as killing any +application that may have locked the server, normally using the +XGrabServer(__libmansuffix__) Xlib function. +.TP 8 +.B Ctrl+Alt+Keypad-Divide +Not treated specially by default. If the +.B AllowDeactivateGrabs +__xconfigfile__(__filemansuffix__) file option is specified, this key sequence +deactivates any active keyboard and mouse grabs. +.TP 8 +.B Ctrl+Alt+F1...F12 +For BSD and Linux systems with virtual terminal support, these keystroke +combinations are used to switch to virtual terminals 1 through 12, +respectively. This can be disabled with the +.B DontVTSwitch +__xconfigfile__(__filemansuffix__) file option. +.SH CONFIGURATION +.B __xservername__ +typically uses a configuration file called +.B __xconfigfile__ +for its initial setup. +Refer to the __xconfigfile__(__filemansuffix__) manual page for information +about the format of this file. +.PP +Starting with version 4.4, +.B __xservername__ +has a mechanism for automatically generating a built-in configuration +at run-time when no +.B __xconfigfile__ +file is present. The current version of this automatic configuration +mechanism works in three ways. +.PP +The first is via enhancements that have made many components of the +.B __xconfigfile__ +file optional. This means that information that can be probed or +reasonably deduced doesn't need to be specified explicitly, greatly +reducing the amount of built-in configuration information that needs to +be generated at run-time. +.PP +The second is to use an external utility called getconfig(1), when +available, to use meta-configuration information to generate a suitable +configuration for the primary video device. The meta-configuration +information can be updated to allow an existing installation to get the +best out of new hardware or to work around bugs that are found +post-release. +.PP +The third is to have "safe" fallbacks for most configuration information. +This maximises the likelihood that the +.B __xservername__ +server will start up in some usable configuration even when information +about the specific hardware is not available. +.PP +The automatic configuration support for __xservername__ is work in progress. +It is currently aimed at the most popular hardware and software platforms +supported by __xservername__. Enhancements are planned for future releases. +.SH FILES +The +.B __xservername__ +server config file can be found in a range of locations. These are +documented fully in the __xconfigfile__(__filemansuffix__) manual page.

Options with command line equivalents are overridden when their +command line equivalent is used. The options recognised by this section +are: +.TP 7 +.BI "Option \*qDefaultServerLayout\*q \*q" layout-id \*q +This specifies the default +.B ServerLayout +section to use in the absence of the +.B \-layout +command line option. +.TP 7 +.BI "Option \*qNoTrapSignals\*q \*q" boolean \*q +This prevents the __xservername__ server from trapping a range of unexpected +fatal signals and exiting cleanly. Instead, the __xservername__ server will die +and drop core where the fault occurred. The default behaviour is +for the __xservername__ server to exit cleanly, but still drop a core file. In +general you never want to use this option unless you are debugging +an __xservername__ server problem and know how to deal with the consequences. +.TP 7 +.BI "Option \*qDontVTSwitch\*q \*q" boolean \*q +This disallows the use of the +.BI Ctrl+Alt+F n +sequence (where +.RI F n +refers to one of the numbered function keys).

Default: off. +.br +Note that the options +.BI AllowDeactivateGrabs +and +.BI AllowClosedownGrabs +will allow users to remove the grab used by screen saver/locker programs. +An API was written to such cases. If you enable this option, make sure +your screen saver/locker is updated. +.TP 7 +.BI "Option \*qHandleSpecialKeys\*q \*q" when \*q +This option controls when the server uses the builtin handler to process +special key combinations (such as +.BR Ctrl+Alt+Backspace ). +Normally the XKEYBOARD extension keymaps will provide mappings for each +of the special key combinations, so the builtin handler is not needed +unless the XKEYBOARD extension is disabled. The value of +.I when +can be +.BR Always , +.BR Never , +or +.BR WhenNeeded . +Default: Use the builtin handler only if needed. The server will scan +the keymap for a mapping to the +.B Terminate +action and, if found, use XKEYBOARD for processing actions, otherwise +the builtin handler will be used. +.SH MODULE SECTION +The +.B Module +section is used to specify which __xservername__ server modules should be loaded. +This section is ignored when the __xservername__ server is built in static form. +The types of modules normally loaded in this section are __xservername__ server +extension modules, and font rasteriser modules. Most other module types +are loaded automatically when they are needed via other mechanisms. +The +.B Module +section is optional, as are all of the entries that may be specified in +it. +.PP +Entries in this section may be in two forms. The first and most commonly +used form is an entry that uses the +.B Load +keyword, as described here: +.TP 7 +.BI "Load \*q" modulename \*q +This instructs the server to load the module called +.IR modulename . +The module name given should be the module's standard name, not the +module file name. The standard name is case-sensitive, and does not +include the "lib" prefix, or the ".a", ".o", or ".so" suffixes. +.PP +.RS 7 +Example: the Type 1 font rasteriser can be loaded with the following entry: +.PP +.RS 4 +.B "Load \*qtype1\*q" +.RE +.RE +.PP +The second form of entry is a +.BR SubSection, +with the subsection name being the module name, and the contents of the +.B SubSection +being +.B Options +that are passed to the module when it is loaded. +.PP +Example: the extmod module (which contains a miscellaneous group of +server extensions) can be loaded, with the __xservername__-DGA extension +disabled by using the following entry: +.PP +.RS 4 +.nf +.B "SubSection \*qextmod\*q" +.B " Option \*qomit XFree86-DGA\*q" +.B EndSubSection +.fi +.RE +.PP +Modules are searched for in each directory specified in the +.B ModulePath +search path, and in the drivers, input, extensions, fonts, and +internal subdirectories of each of those directories. +In addition to this, operating system specific subdirectories of all +the above are searched first if they exist. +.PP +To see what font and extension modules are available, check the contents +of the following directories: +.PP +.RS 4 +.nf +__projectroot__/lib/modules/fonts +__projectroot__/lib/modules/extensions +.fi +.RE +.PP +The "bitmap" font modules is loaded automatically. It is recommended +that at very least the "extmod" extension module be loaded. If it isn't +some commonly used server extensions (like the SHAPE extension) will not be +available. +.SH INPUTDEVICE SECTION +The config file may have multiple +.B InputDevice +sections. There will normally be at least two: one for the core (primary) +keyboard, and one of the core pointer. If either of these two is missing, +a default configuration for the missing ones will be used. Currently the +default configuration may not work as expected on all platforms. +.PP +.B InputDevice +sections have the following format: +.PP +.RS 4 +.nf +.B "Section \*qInputDevice\*q" +.BI " Identifier \*q" name \*q +.BI " Driver \*q" inputdriver \*q +.I " options" +.I " ..." +.B "EndSection" +.fi +.RE +.PP +The +.B Identifier +and +.B Driver +entries are required in all +.B InputDevice +sections.

The +.B Driver +entry specifies the name of the driver to use for this input device. +When using the loadable server, the input driver module +.RI \*q inputdriver \*q +will be loaded for each active +.B InputDevice +section. An +.B InputDevice +section is considered active if it is referenced by an active +.B ServerLayout +section, if it is referenced by the +.B \-keyboard +or +.B \-pointer +command line options, or if it is selected implicitly as the core pointer +or keyboard device in the absence of such explicit references. +The most commonly used input drivers are "keyboard" and "mouse". +.PP +In the absence of an explicitly specified core input device, the first +.B InputDevice +marked as +.B CorePointer +(or +.BR CoreKeyboard ) +is used. If there is no match there, the first +.B InputDevice +that uses the "mouse" (or "keyboard" or "kbd") driver is used. The final +fallback is to use built-in default configurations. +.PP +.B InputDevice +sections recognise some driver-independent +.BR Options , +which are described here. See the individual input driver manual pages +for a description of the device-specific options. +.TP 7 +.BI "Option \*qCorePointer\*q" +When this is set, the input device is installed as the core (primary) +pointer device. There must be exactly one core pointer. If this option +is not set here, or in the +.B ServerLayout +section, or from the +.B \-pointer +command line option, then the first input device that is capable of +being used as a core pointer will be selected as the core pointer. +This option is implicitly set when the obsolete +.B Pointer +section is used. +.TP 7 +.BI "Option \*qCoreKeyboard\*q" +When this is set, the input device is to be installed as the core +(primary) keyboard device. There must be exactly one core keyboard. If +this option is not set here, in the +.B ServerLayout +section, or from the +.B \-keyboard +command line option, then the first input device that is capable of +being used as a core keyboard will be selected as the core keyboard. +This option is implicitly set when the obsolete +.B Keyboard +section is used. +.TP 7 +.BI "Option \*qAlwaysCore\*q \*q" boolean \*q +.TP 7 +.BI "Option \*qSendCoreEvents\*q \*q" boolean \*q +Both of these options are equivalent, and when enabled cause the +input device to always report core events.

A +.B Device +section is considered active if it is referenced by an active +.B Screen +section. +.PP +.B Device +sections recognise some driver-independent entries and +.BR Options , +which are described here. Not all drivers make use of these +driver-independent entries, and many of those that do don't require them +to be specified because the information is auto-detected. See the +individual graphics driver manual pages for further information about +this, and for a description of the device-specific options. +Note that most of the +.B Options +listed here (but not the other entries) may be specified in the +.B Screen +section instead of here in the +.B Device +section. +.TP 7 +.BI "BusID \*q" bus-id \*q +This specifies the bus location of the graphics card. For PCI/AGP cards, +the +.I bus-id +string has the form +.BI PCI: bus : device : function +(e.g., "PCI:1:0:0" might be appropriate for an AGP card). +This field is usually optional in single-head configurations when using +the primary graphics card. In multi-head configurations, or when using +a secondary graphics card in a single-head configuration, this entry is +mandatory. Its main purpose is to make an unambiguous connection between +the device section and the hardware it is representing. This information +can usually be found by running the __xservername__ server with the +.B \-scanpci +command line option. +.TP 7 +.BI "Screen " number +This option is mandatory for cards where a single PCI entity can drive more +than one display (i.e., multiple CRTCs sharing a single graphics accelerator +and video memory). One +.B Device +section is required for each head, and this +parameter determines which head each of the +.B Device +sections applies to. The legal values of +.I number +range from 0 to one less than the total number of heads per entity. +Most drivers require that the primary screen (0) be present. +.TP 7 +.BI "Chipset \*q" chipset \*q +This usually optional entry specifies the chipset used on the graphics +board. In most cases this entry is not required because the drivers +will probe the hardware to determine the chipset type. Don't +specify it unless the driver-specific documentation recommends that you +do. +.TP 7 +.BI "Ramdac \*q" ramdac-type \*q +This optional entry specifies the type of RAMDAC used on the graphics +board. This is only used by a few of the drivers, and in most cases it +is not required because the drivers will probe the hardware to determine +the RAMDAC type where possible. Don't specify it unless the +driver-specific documentation recommends that you do. +.TP 7 +.BI "DacSpeed " speed +.TP 7 +.BI "DacSpeed " "speed-8 speed-16 speed-24 speed-32" +This optional entry specifies the RAMDAC speed rating (which is usually +printed on the RAMDAC chip). The speed is in MHz. When one value is +given, it applies to all framebuffer pixel sizes. When multiple values +are give, they apply to the framebuffer pixel sizes 8, 16, 24 and 32 +respectively. This is not used by many drivers, and only needs to be +specified when the speed rating of the RAMDAC is different from the +defaults built in to driver, or when the driver can't auto-detect the +correct defaults. Don't specify it unless the driver-specific +documentation recommends that you do. +.TP 7 +.BI "Clocks " "clock ..." +specifies the pixel that are on your graphics board. The clocks are in +MHz, and may be specified as a floating point number. The value is +stored internally to the nearest kHz. The ordering of the clocks is +important. It must match the order in which they are selected on the +graphics board. Multiple +.B Clocks +lines may be specified, and each is concatenated to form the list. Most +drivers do not use this entry, and it is only required for some older +boards with non-programmable clocks.
