Comment 17 for bug 3527

I have a similar problem to the one described in this bug report. My machine freezes randomly and if it does, the mouse pointer often can still be moved around, but the keyboard does not work anymore (i.e. ctrl alt backspace does not work). I have also tried to login from outside via SSH, but the machine seemed to be completely locked up each time I tried. Only pushing the reset button helped in this situation.

I experienced not only crashes with the opengl screensavers, but also with games that use 3d acceleration (e.g. tuxracer and others), even with glxgears.

Deactivating 3d acceleration allows to end the crashes (I commented out the "Load dri" part in the "Section Module"), but this is of course not a solution to the problem.

Here my software specs:
Ubuntu Breezy with Ubuntu Breezy kernel 2.6.12, Ubuntu Breezy xorg 6.8.2 with the opensource ATI drivers. Kubuntu desktop (currently with KDE version 3.5.1) and ReiserFS filesystem.

Here my hardware specs:
- SMP, dual PIII
- VIA Motherboard
- Radeon 8500 LE graphics card
