The screen becomes glitched looking, and sometimes static plays over the speakers. Changing Desktop Environments and Window Managers does not change this. Dropping to a terminal via ctrl+alt+F1 seems to be unaffected. I thought this was an issue with X11 as per this (https://wiki.ubuntu.com/X/Troubleshooting/Freeze), but if I ssh into the machine, it becomes unresponsive after the crash.
