[Bug 1260752] [NEW] System completely locked up - requires forced shutdown


Public bug reported:

This isn't the first time this has happened in 13.10 for me, but it's
the first time since I performed a fresh install. I was hoping the
previous lockups were caused by an upgrade snaffu since I had upgraded
from 13.04 previously but apparently not.

This is as serious a fail as I can imagine (without actually CAUSING
hardware damage), so I hope this gets sufficient attention.

I had several windows open last night, including terminal (with X11
forwarding), firefox, reimanna, text editor, etc. The screen was black
this morning, but wouldn't wake up. I could see the mouse cursor move,
but all else was black. The arrow of the mouse would turn into a 'hand'
at certain parts of the screen, as if it was aware that it was hovering
over a link in Firefox.

Switching to tty2 I attempted to kill processes until the desktop came
back. I killed compiz two times and each time when switching back to
tty7 I was able to see graphics on the screen. The first time I saw my
unlocked desktop for a brief moment; and the second time it presented me
a login box. I entered my pw and the screen went black again. I killed
compiz again and immediately afterwards the entire workstation was
unresponsive as in I could not switch between tty's anymore so was
forced to hard-power off the machine.
