locking mechanism on monitor

[Teresa Salyer]

Help.   I was working in grass and went to display a raster map and my
monitor would not respond giving me the following message:

locking mechanism failed
lock file  <where located>.

 That lock file was empty.  I rebooted my computer and still no response
from x0 monitor. What happened ???  I can bring up another monitor x1
but my x0 will not respond.

Is there a way to fix this problem.  Thanks for your help .
