Xsun, XsunMono, Xsun24 - Sun server for X
Xsun [ option ] ...
Xsun is the server for Version
11 of the X window system on Sun hardware. It will normally be started by
daemon or by a script that runs the program xinit(1)
supports the BW2 monochrome frame buffer. Xsun supports the CG2, CG3, CG4,
and CG6 8-bit color frame buffers in addition to the BW2 monochrome frame
buffer. On Solaris 2.5 it also supports the TCX as an 8-bit color frame buffer.
Xsun24 supports the cgeight 24-bit color frame buffer in addition to the
8-bit color and monochrome frame buffers that Xsun supports.
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.
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-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
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
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 corresponding key.
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.
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
in the /dev 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 bwtwo0 on the CPU board. So if /dev has a special
file for /dev/bwtwo0, the server will use it, even though there is no
monitor attached to the monochrome framebuffer. 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 /dev 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.
