Public bug reported:
According to ubuntu-bug, I'm having GPU lockups. I have an old HP PC
with a NVIDIA GeForce 8500GT video card. It seems to freeze mostly
within 10 or so minutes of logging in- if I go for more than that
without a lockup, it seems the whole session will be issue-free. I've
had it happen while watching YouTube videos in both Firefox and Chrome,
playing music on Spotify, installing packages with Synaptic, and logging
in. The screen freezes and the only way to continue is to hold down the
power button and reboot the computer. Alt+SysReq+K and REISUB don't
work. If audio is playing, the last second or so of audio will continue
to loop until the computer is reset. I've used both the NVIDIA
recommended drivers and the Nouveau drivers, and the problem has
persisted. My install is only 11 days old, so I haven't had it in a
100% working state yet. A photo of the screen won't help, since it
freezes on whatever I was doing last. Any help would be appreciated!
1. Ubuntu 12.10 amd64
2. xorg 1:7.7+1ubuntu4
3. Computer should not freeze during use or should be able to be rebooted with
REISUB or Alt+Sysreq+K.
4. Computer freezes during use and can't be recovered without resetting it.
