Screen Freeze

[Per-Anton Rønning]

Hi all.
A very annoying feature has suddenly caught up with me,  now when 
running FC5.
This has been a plague earlier with other distros, and after installing 
FC5 it was "clean" for quite some time, until suddenly and with no 
apparent motivation the screen freezes, i.e., no keyboard typing and no 
mouseclicks are accepted.  Programs are still running, I have a back 
door via my old backup machine, that is, I can establish a 
SSH-connection and do a controlled shutdown via that back door. If I am 
runnig emacs it seems to save the latest input in a #<filename.cc># 
file, so nothing is lost. But it is annoying hainv to restart the 
computer so frequently.
Has anyone else experienced this? Has anyone (in case) found a cure, or 
is this something I have to live with?
Could it be hardware related? Or driver related?
I would be very thankful to have some comments on this.
