Public bug reported:
After upgrade to raring and reboot, I'm seeing frequent Freezes in
normal usage of X. The mouse cursor moves but cannot interact with
windows.
ctrl-alt-f1 will work, and I can login there.
Running 'sudo restart lightdm' from the console ends up with multiple X
processes running, and screen goes blank, and I can no longer use the console
at all (although ssh access is still available).
Here is info in /var/log/syslog:
