Status in xserver-xorg-video-nouveau package in Ubuntu: Invalid Bug description: Every once in a while, usually when I've been reading news and blogs for a couple of hours, the display freezes up and doesn't respond to any mouse clicking. Doing ctrl-alt-backspace works as well as ctrl- alt-f1. I've noticed that if the problem happens a lot in a short period of time, eventually update-notifier will tell me updates are available. When I tried ctrl-alt-f1 and ran tops, that's when I discovered compiz was using 100% cpu so that was what was causing the display to not respond. I don't know many commands, but killall compiz did allow me to continue reading the blog, but of course all window decoration was missing and I had no way to launch other applications through the gui. After doing ctrl-alt-backspace to restore my desktop, Apport reported an update-notifier crash. Since this problem happens at times I'm not doing anything but reading what's already in the browser and trying to scroll down to read more, I think the problem is caused by something done on a schedule. Since update-notifier always seems to come up eventually on reboot or ctrl- alt-backspace, it would seem like update-notifier is somehow causing compiz to use 100% cpu at times.
