Complete X lockup when running beryl/compiz
When I'm running beryl or compiz on the 9629 driver I (randomly, usually infrequently) get what appears to be a complete system lockup. I can move the mouse but can't click on anything, caps lock and num lock don't work, and ctrl-sysrq-k/r do nothing.
I finally managed to have this happen when I was around another machine and managed to ssh into the locked system. Killing X and reloading the nvidia kernel module seems to fix things. I've got a nvidia-bug-report.log file that I'm attaching.
Note: I have not seen this problem when running metacity but since it happens so rarely it might just be coincidence.
