Public bug reported:

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.
