Description of problem:
When running a GL screensaver xscreensaver will occasionally hang.
Steps to Reproduce:
1. Using xscreensaver-demo, enable blanking, cycling, locking and power
management and activate GL screensavers.
2. Lock console in X.
Actual Results: After a while the screensaver will hang (motion on screen
stops), DPMS won't power down monitor ever, and keyboard activity is
ignored (can't get to virtual consoles or type password to unlock screen).
Expected Results: Screensaver should keep running and typing password
should unlock screen.
Although the keyboard becomes useless, it is still possible to access the
machine from the network. Issuing init 3, does nothing. The only thing
that I've found works is rebooting the machine. A core file is created by
So far I've seen hangs with Rubik, Planetary Gears, Cage and Atlantis.
The machine is a Pentium II/266 with a Voodoo3 PCI card.
I'm attaching the core file from a crash with Cage.
Created attachment 24347 [details]
Core file from shutdown after hang of cage screen saver.

I need you to attach your X server log, your X config file, your
/var/log messages file as individual file attachments using the
Please provide the requested information.
When I get the time to intentionally let my system crash, I'll get these for
you. However, right now I really need this system up and running to do my job.
Ok, when you get a chance to provide the necessary debugging information,
please reopen the report with the files attached below.
I've had this hang occur again. The system is now a Pentium III/533 with the
same Voodoo 3 card. I've checked /var/log/messages and /var/log/XFree86.0.log
but neither seem to provide any useful information. Also, I'm now unable to
locate the core file. Please give me a list of the exact files including their
paths just in case I encounter this hang again.
And it crashed again... What $path/$files do you need?
