NAME
       XFree86 - X11R6 X server

SYNOPSIS
       XFree86 [:display] [option ...]

DESCRIPTION
       XFree86	is an X server that was originally designed for UNIX and UNIX-like operating sys-
       tems running on Intel x86 hardware.  It now runs on a wider range of hardware and OS plat-
       forms.

       This  work  was originally derived from X386 1.2 which was contributed to X11R5 by Snitily
       Graphics Consulting Service.  The XFree86 X server architecture was redesigned for the 4.0
       release,  and  it  includes  among  other things a loadable module system donated by Metro
       Link, Inc.  The current XFree86 release is compatible with X11R6.6.

CONFIGURATIONS
       XFree86 operates under a wide range of operating  systems  and  hardware  platforms.   The
       Intel x86 (IA32) architecture is the most widely supported hardware platform.  Other hard-
       ware platforms include Compaq Alpha, Intel IA64, SPARC and PowerPC.  The most widely  sup-
       ported 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.  Dar-
       win and Mac OS X are supported with the XDarwin(1) X server.   Win32/Cygwin  is	supported
       with the XWin X server.

NETWORK CONNECTIONS
       XFree86 supports connections made using the following reliable byte-streams:

       Local
	   On  most platforms, the "Local" connection type is a UNIX-domain socket.  On some Sys-
	   tem V platforms, the "local" connection types also include STREAMS pipes, named pipes,
	   and some other mechanisms.

       TCPIP
	   XFree86  listens  on port 6000+n, where n is the display number.  This connection type
	   can be disabled with the -nolisten option (see the Xserver(1) man page for details).

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  XLOCAL  environment  variable
       described  below.   If  the display name indicates a best-choice connection should be made
       (e.g. :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 unix:0.0.

       The XLOCAL environment variable should contain a list of one more more of the following:

	       NAMED
	       PTS
	       SCO
	       ISC

       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.  XLO-
       CAL=NAMED), or an ordered list (e.g. XLOCAL="NAMED:PTS:SCO").  This variable overrides the
       compiled-in defaults.  For SVR4 it is recommended that NAMED be the first preference  con-
       nection.  The default setting is PTS:NAMED:ISC:SCO.

       To  globally  override the compiled-in defaults, you should define (and export if using sh
       or ksh) XLOCAL globally.  If you use startx/xinit, the definition should be at the top  of
       your  .xinitrc  file.   If  you	use  xdm,  the	definitions  should  be  early	on in the
       /usr/X11R6/lib/X11/xdm/Xsession script.

OPTIONS
       In addition to the normal server options described in the Xserver(1) manual page,  XFree86
       accepts the following command line switches:

       vtXX    XX  specifies  the Virtual Terminal device number which XFree86 will use.  Without
	       this option, XFree86 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.

       -allowMouseOpenFail
	       Allow the server to start up even if the mouse device  can't  be  opened  or  ini-
	       tialised.   This  is  equivalent  to  the  AllowMouseOpenFail  XF86Config(5x) file
	       option.

       -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 AllowNonLocalModInDev XF86Config(5x) file option.

       -allowNonLocalXvidtune
	       Make the VidMode extension available to remote clients.	This allows the  xvidtune
	       client to connect from another host.  This is equivalent to the AllowNonLocalXvid-
	       tune XF86Config(5x)  file  option.   By	default  non-local  connections  are  not
	       allowed.

       -bgamma value
	       Set  the blue gamma correction.	value must be between 0.1 and 10.  The default is
	       1.0.  Not all drivers support this.  See also the  -gamma,  -rgamma,  and  -ggamma
	       options.

       -bpp n  No  longer  supported.	Use  -depth to set the color depth, and use -fbbpp if you
	       really need to force a non-default framebuffer (hardware) pixel format.

       -configure
	       When this option is specified, the X server loads all video driver modules, probes
	       for  available  hardware,  and  writes out an initial XF86Config(5x) 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).

       -crt /dev/ttyXX
	       SCO only.  This is the same as the vt option, and is  provided  for  compatibility
	       with the native SCO X server.

       -depth n
	       Sets  the default color depth.  Legal values are 1, 4, 8, 15, 16, and 24.  Not all
	       drivers support all values.

       -disableModInDev
	       Disable dynamic modification of input device settings.  This is equivalent to  the
	       DisableModInDev XF86Config(5x) file option.

       -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  DisableVidMode-
	       Extension XF86Config(5x) file option.

       -fbbpp n
	       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  -depth
	       above.	Useful	if  you want to run a depth 24 configuration with a 24 bpp frame-
	       buffer 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.

       -flipPixels
	       Swap the default values for the black and white pixels.

       -gamma value
	       Set  the gamma correction.  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  -rgamma,  -bgamma, and -ggamma options.  Not all drivers
	       support this.

       -ggamma value
	       Set the green gamma correction.	value must be between 0.1 and 10.  The default is
	       1.0.   Not  all	drivers  support this.	See also the -gamma, -rgamma, and -bgamma
	       options.

       -ignoreABI
	       The X 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.

       -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.

       -keyboard keyboard-name
	       Use the XF86Config(5x) file InputDevice section called keyboard-name as	the  core
	       keyboard.   This  option  is ignored when the Layout section specifies a core key-
	       board.  In the absence of both a Layout section and this option, the  first  rele-
	       vant InputDevice section is used for the core keyboard.

       -layout layout-name
	       Use  the  XF86Config(5x)  file  Layout section called layout-name.  By default the
	       first Layout section is used.

       -logfile filename
	       Use the file called filename as the X server log file.  The default  log  file  is
	       /var/log/XFree86.n.log  on  most platforms, where n is the display number of the X
	       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).

       -logverbose [n]
	       Sets the verbosity level for information printed to the X server log file.  If the
	       n value isn't supplied, each occurrance of this option  increments  the	log  file
	       verbosity  level.   When  the n value is supplied, the log file verbosity level is
	       set to that value.  The default log file verbosity level is 3.

       -modulepath searchpath
	       Set the module search path to searchpath.  searchpath is a comma separated list of
	       directories  to	search	for X server modules.  This option is only available when
	       the server is run as root (i.e, with real-uid 0).

       -nosilk Disable Silken Mouse support.

       -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 equvalent to the Pixmap XF86Config(5x) file
	       option.

       -pixmap32
	       Set the internal pixmap format for depth 24 pixmaps to 32 bits per pixel.  This is
	       usually the default.  This is equvalent to the Pixmap XF86Config(5x) file option.

       -pointer pointer-name
	       Use  the  XF86Config(5x)  file InputDevice section called pointer-name as the core
	       pointer.  This option is ignored when the Layout section specifies a core pointer.
	       In the absence of both a Layout section and this option, the first relevant Input-
	       Device section is used for the core pointer.

       -probeonly
	       Causes the server to exit after the device probing stage.  The XF86Config file  is
	       still  used  when  this	option is given, so information that can be auto-detected
	       should be commented out.

       -quiet  Suppress most informational messages at startup.  The verbosity level  is  set  to
	       zero.

       -rgamma value
	       Set  the  red gamma correction.	value must be between 0.1 and 10.  The default is
	       1.0.  Not all drivers support this.  See also the  -gamma,  -bgamma,  and  -ggamma
	       options.

       -scanpci
	       When this option is specified, the X server scans the PCI bus, and prints out some
	       information about  each	device	that  was  detected.   See  also  scanpci(1)  and
	       pcitweak(1).

       -screen screen-name
	       Use  the  XF86Config(5x)  file  Screen section called screen-name.  By default the
	       screens referenced by the default Layout section are used,  or  the  first  Screen
	       section when there are no Layout sections.

       -showconfig
	       This  is  the  same as the -version option, and is included for compatibility rea-
	       sons.  It may be removed in a future release, so the  -version  option  should  be
	       used instead.

       -weight nnn
	       Set  RGB  weighting  at	16  bpp.  The default is 565.  This applies only to those
	       drivers which support 16 bpp.

       -verbose [n]
	       Sets the verbosity level for information printed on stderr.  If the n value  isn't
	       supplied, each occurrance of this option increments the verbosity level.  When the
	       n value is supplied, the verbosity level is set to that value.  The  default  ver-
	       bosity level is 0.

       -version
	       Print out the server version, patchlevel, release date, the operating system/plat-
	       form it was built on, and whether it includes module loader support.

       -xf86config file
	       Read the server configuration from 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.

KEYBOARD
       The XFree86 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  combi-
       nations	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  XKEY-
       BOARD extension, which key combinations perform which actions is completely configurable.

       For more information about when the builtin event handler is used to recognize the special
       key combinations, see the documentation on the HandleSpecialKeys option	in  the  XF86Con-
       fig(5x) man page.

       The special combinations of key presses recognized directly by XFree86 are:

       Ctrl+Alt+Backspace
	       Immediately kills the server -- no questions asked.  This can be disabled with the
	       DontZap XF86Config(5x) file option.

       Ctrl+Alt+Keypad-Plus
	       Change video mode to next one specified in the configuration file.   This  can  be
	       disabled with the DontZoom XF86Config(5x) file option.

       Ctrl+Alt+Keypad-Minus
	       Change  video  mode to previous one specified in the configuration file.  This can
	       be disabled with the DontZoom XF86Config(5x) file option.

       Ctrl+Alt+Keypad-Multiply
	       Not treated specially by default.  If the AllowClosedownGrabs XF86Config(5x)  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(3x) Xlib function.

       Ctrl+Alt+Keypad-Divide
	       Not treated specially by default.  If the AllowDeactivateGrabs XF86Config(5x) file
	       option is specified, this key sequence deactivates any active keyboard  and  mouse
	       grabs.

       Ctrl+Alt+F1...F12
	       For  BSD and Linux systems with virtual terminal support, these keystroke combina-
	       tions are used to switch to virtual terminals 1 through	12,  respectively.   This
	       can be disabled with the DontVTSwitch XF86Config(5x) file option.

SETUP
       XFree86	uses  a configuration file called XF86Config for its initial setup.  Refer to the
       XF86Config(5x) manual page for information about the format of this file.

FILES
       The X server config file can be found in a range of locations.  These are documented fully
       in the XF86Config(5x) manual page.  The most commonly used locations are shown here.
