Red Hat Bugzilla – Bug 121846
(DRI I845) System hangs/crashes w/OpenGL screensaver

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):
Steps to Reproduce:
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
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.
