I am trying to run grass4.0 on a SUN sparc IPX, and cannot
get the graphics monitor work properly. It keeps giving me
the following message:

  GRASS 4.0 > d.mon start=x0
  Graphics driver [x0] is already running
  Error - Could not complete locking process for monitor <x0>.
  Lock file is /applications/grass4.0/locks/dolphin/:0.0/x0
  Problem selecting x0. Will try once more
  ERROR - eof from graphics monitor.

I wonder if any of you had this problem before. It would be greatly
appreciated if anyone can give me a hint how to fix it.
