NAME
     Xsun - Solaris server for X Version 11

SYNOPSIS
     Xsun [ option ] ...

DESCRIPTION
     Xsun is the Solaris server for Version 11 of  the  X  window
     system  on  Solaris  hardware.   It  is  normally started by
     xinit(1) via openwin(1).

OPTIONS
     In addition to the options  described  in  Xserver(1),  Xsun
     accepts the following command-line switches:

     -dev filename
             This option specifies the name  of  the  framebuffer
             device file to be used instead of the default frame-
             buffer /dev/fb.  Multiple instances of  this  option
             indicate multiple screens on the same server.  After
             each -dev option a list  of  modifiers  changes  the
             behavior of the named device.

             [ left | right | top | bottom ]
                  Specify the position of a given screen in rela-
                  tion  to  the previous one on the command line.
                  The default right.

             dpix n
                  The dpi in the x direction for this  screen  is
                  n.  The default is 90.

             dpiy n
                  The dpi in the y direction for this  screen  is
                  n.  The default is 90.

             defclass [ GrayScale | StaticGray | PseudoColor |
                  StaticColor | DirectColor | TrueColor ] Use the
                  specified  visual  as  the default visual.  The
                  default is device dependent.

             defdepth n
                  A visual of depth n is the default visual.  The
                  default is device dependent.

             grayvis
                  Only report GrayScale and/or  StaticGray  visu-
                  als.

             The following is an example of the -dev option  that
             might be used on a system with a cg6 and a bw2:

                  -dev  /dev/cgsix0   defclass   GrayScale   -dev
             /dev/bwtwo0 right

             The Xsun server also supports the format used by the
             X11R6  sample  X Server. Multiple screen systems are
             specified by using the following syntax on the  com-
             mand line:

                  -dev <device 1>:<device 2>:...:<device n>

             The server uses device 1 as screen 0,  device  2  as
             screen  1, etc., and the server assumes that screens
             are  ordered  left  to  right  in  ascending  screen
             number.   This  means  that the cursor moves off the
             right side of screen n and onto  the  left  side  of
             screen  n  +  1.  When this format is used, no other
             -dev options are valid.


     - accessX
             This option enables activation of  the  slowkey  and
             stickykey  functionality  of  the  AccessX extension
             using the shift key on the keyboard.

     -ar1 milliseconds
             Specify amount of  time  in  milliseconds  before  a
             pressed key begins to autorepeating.  The default is
             500 milliseconds.  This option is not  available  on
             Solaris x86 or PowerPC.

     -ar2 milliseconds
             specify  the  interval   in   milliseconds   between
             autorepeats of pressed keys.  The default is 50 mil-
             liseconds.  This option is not available on  Solaris
             x86 or PowerPC.

     -banner Display the OpenWindows banner  screen  at  startup.
             The banner is displayed by default.

     -dur milliseconds
             Set the duration  of  the  bell  in  units  of  mil-
             liseconds.  Default is 100.

     -dpsfileops
             Allow the Display PostScript file  operators  access
             to the UNIX file system.

     -flipPixels
             Reverse black  and  white  pixel  locations  in  the
             colormap.   This  is not the same as a reverse video
             option.

     -pit percentage
             Set the percentage of the maximum pitch available to
             the  hardware.  Sun hardware does not support alter-
             native pitch values.

     -mden denominator
             Set  the  pointer  acceleration  denominator.    The
             acceleration  numerator  is  set  with the -a option
             described in Xserver(1).   This  permits  fractional
             acceleration  such  as 3/2 or 1.5.  Default value is
             1.

     -nobanner
             Do not display  the  OpenWindows  banner  screen  at
             startup.

     -nominexp
             This option is used to disable "minimized exposure",
             which  is used only by multi-planegroup devices such
             as gt, cg12 and  cg8.   "Minimized  Exposure"  means
             that the server will not send  expose events to win-
             dows in one planegroup that are exposed  by  windows
             in  another  planegroup.   By  default the minimized
             exposure feature is turned ON.

     -sharedretainedpath directory_path
             This option is  currently  supported  only  for  Sun
             internal software APIs.

NETWORK CONNECTIONS
     In  addition  to  the  network  connections   described   in
     Xserver(1), Xsun provides the following connection:

     Shared Memory
         Sun provides a shared memory transport mechanism via the
         SUN_SME extension.  This extension provides the capabil-
         ity of sending client requests to the server via  shared
         memory.  Shared memory is used for client requests only.
         Replies from the server and  events  are  sent  via  the
         default  transport  mechanism.  To enable this transport
         mechanism, one has to set the DISPLAY environment  vari-
         able to :x.y (where x is the display number and y is the
         screen number), and the environment  variable  XSUNTRAN-
         SPORT to "shmem".  The size of the segment can be set by
         setting enviroment variable XSUNSMESIZE.  By default, it
         is set to "64" which implies that the size of the shared
         memory segment is 64K.

POWER MANAGEMENT
     Xsun screen-saver causes displays to be power  managed.  The
     default   video-off  screen-saver  preference  achieves  the
     effect of turning  off  the  video  by  power  managing  the
     display. Instead of calling directly into the frame buffer's
     driver to turn the video off,  Xsun  calls  into  the  power
     management  pseudo  driver (pm(7D)) to request the change in
     power level of the display. It turns the video-off  by  set-
     ting  the  power  level  of the display to zero and turns it
     back on by setting the display to its normal operating power
     level.

     The Xsun support for display power management  is  currently
     only  available  on  the  SPARC  platform.  See  Using Power
     Management for more information.
