Description O.K. 2004-04-28 12:49:20 EDT
From Bugzilla Helper:
User-Agent: Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.0)

Description of problem:
The system, configured to random screensaver, used to 'hang' from 
time to time.
Activating xscreensaver-demo and (accidently) choosing an OpenGL 
screensaver "freeses" the display and hangs the whole machine.
Non OpenGL screensavers work fine (and xscreensaver-demo w/non-OpenGL)
Machine detailes: Compaq Evo, Pentium4@1.8GHz, 256MB RAM
Video card: "82845G/GL [Brookdale-G] Chipset Integrated Graphics 

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1.Run xscreensaver-demo
2.Choose (click on-) an OpenGL screensaver - the machine hangs!
1. Edit ~/.xscreensave to run an OpenGL screensaver
2. lock the screen


Actual Results:  as expected, the machine hung.

Expected Results:  the xscreensaver/xscreensaver-demo should run :-)

This is happening for me on Fedora Core 2 test 3, up to date as of
right now.

When hung, the system does not respond to Ctrl-Alt-F keys, nor does it
shut down as normal when the ACPI power switch is pressed. The hang
freezes ssh connections, but the system still responds to pings.
