We are using a .xserverrc to get the -dev /dev/cgfour0 option set for Xsun.
The only reason we are doing that is because Xsun fails to display anything
on /dev/bwtwo0.  Xsun does not even display the gray stippled root window or
the X cursor on /dev/bwtwo0.  However, if we do not restrict Xsun to 
/dev/cgfour0 via the option, moving the mouse near the left and right edges
of the screen causes the prior /dev/bwtwo0 display to flash on in place of
the /dev/cgfour0 display, then the reverse when the mouse moves back to the
screen from the edge.  That behavior goes beyond being useless, into the
realm of the disconcerting.

The .x*rc files are in the workstation's user's home directory.
Here's the .xserverrc:
  Xsun -dev /dev/cgfour0 -dev /dev/bwtwo0

And the .xinitrc we're using (the host's name is squall):
  uwm -d squall:0.0 -f .uwmrc&
  xterm -fn -adobe-courier-bold-r-normal--14-140-75-75-m-90-iso8859-1 -C
