Bug Description

hi this is affecting a lot of users it seems. whether we all have the same issue or not i don't know, but a lot of peoples' systems are crashing, locking up hard so you can't do anything except pull the plug and reboot.

i'm on gutsy amd64, 4gb ram, nvidia - tried nvidia and nv in xorg. also tried desktop effects turned on and off. still locks up after 5mins or 2 days or anything in between...

here is a thread with a lot of this going on:
