Public bug reported:
I was away from my computer, returned, and found Ubuntu sitting at the
login screen because X had crashed.
Then after a few minutes of using my computer after logging back in, my
computer completely froze. (Mouse, keyboard entirely unresponsive).
Here is content from /var/log/kern.log from when the crash of X occurred:
