Xsun, XsunMono, Xsun24 - Sun server for X Version 11
[ option ] ...
is the server for Version 11 of the X window system on Sun hardware.
It will normally be started by the xdm(1) daemon or by a script
that runs the program xinit(1).
supports 8-bit color and 1-bit monochrome screens.
is configured to support only monochrome screens, for low-end systems
with limited memory.
supports 8-bit color and 1-bit monochrome screens in addition to the
cgeight 24-bit color screen.
If specific framebuffer device files aren't specified on the command
line with the -dev switch or in the XDEVICE environment
variable, the server will search for all installed frame buffers and
will use all those that it finds. The following framebuffer types are
- bwtwo, cgtwo, cgthree, cgfour, cgsix, and cgeight.
Finally, if no specific framebuffers are found, the generic framebuffer
interface /dev/fb is used.
Xsun, Xsun24, and XsunMono support the Type-2, Type-3, and many variations
of the Type-4 and Type-5 keyboards.
Type-4 and Type-5 keyboards feature a key labeled AltGraph which
is a mode-shift key. The mode-shift key is used to generate the symbols
painted on the fronts of the keys. The mode-shift key works exactly like
the Shift, Control, Alt, and <Meta> keys.
The ten function keys on the left side of the Type-5 keyboard may be
considered as having L1..L10 painted on their fronts. Shift-AltGraph
will cause different keysyms to be generated for some keys, e.g. the
Type-5 SysRq key.
For compatibility with Sun's X11/NeWS server, the F11 and F12 keys may
be made to generate the equivalent X11/NeWS keysyms by using mode-switch.
For backwards compatibility, the normal and mode-shifted keysyms for
the ten function keys on the left side of Type-4 and Type-5 keyboards
may be swapped via command line option. See -swapLkeys.
The X LEDs 1..4 correspond to the NumLock, ScrollLock, Compose, and
CapsLock LEDs respectively. Pressing the key once turns the corresponding
LED on. Pressing the key again turns the LED off. Turning an LED on or
off with e.g. 'xset [-]led ' is equivalent to pressing the
In addition to the normal server options described in the Xserver(1)
manual page, Xsun accepts the following command line switches:
- -ar1 milliseconds
This option specifies amount of time in milliseconds before which a
pressed key should begin to autorepeat.
- -ar2 milliseconds
This option specifies the interval in milliseconds between autorepeats
of pressed keys.
Swaps the normal keysyms for the function keys on the left side of
Type-4 and Type-5 keyboards with the alternate keysyms, i.e. the keysyms
painted on the front of the keys.
The normal pixel values for white and black are 0 and 1 respectively.
When -flipPixels is specified these values are reversed.
When used with the cgtwo, this option indicates that the server
should emulate a monochrome framebuffer instead of the normal color
framebuffer. When used with the cgfour, this option indicates
that the monochrome screen should be numbered 0 and the color screen
numbered 1 (instead of the other way around).
This option disables switching between screens by sliding the mouse off
the left or right edges. With this disabled, a window manager function
must be used to switch between screens.
This option indicates that the server is being run from a debugger, and
that it should not put its standard input, output and error files
into non-blocking mode.
- -dev filename[:filename]...
This option specifies the colon separated names of the framebuffer device
files to be used.
This option indicates that the server should enumerate the available
frame buffers that it will use.
If present, and if no explicit -dev options are given, specifies
the (colon separated) list of display devices to use.

The auto-configuration depends on there being appropriate special files
directory for the framebuffers which are to be used. Extra entries can
confuse the server. For example, the X/160C in fact has the hardware
for a monochrome
on the CPU board. So if
has a special file for

The server will appear to start, but not to paint a cursor, because the
cursor is on the monochrome frame buffer. The solution is to remove the
entries for any device you don't have a monitor for.
There is a bug in pre-FCS operating systems for the Sun-4 which causes
the server to crash driving a cgtwo.
