Is the system locked up hard or are the graphics just corrupt?

Does:
Option "AccelMethod" "EXA"
Help?
Comment 2 Thomas Reinhold 2008-12-08 07:28:35 UTC 
graphics are just corrupt. When I perform a "ctrl+del+backspace" X "reboots" and I'm good to go again.
Will try the 
Option "AccelMethod" "EXA"
and report back.
