Hmm, I've had a mpv playing a video file hard lock-up a system
several
times (dunno if it was a corrupt video file, or another cause).
Suddenly the screen would go oddly darker, looking like there was a
flyscreen in front of the image, then start to smear video as it
slowly
drew on the screen.
I expected to be able to CTRL ALT BACKSPACE to kill X and recover,
but
rarely did it recover from this. The system seems far from crash-
proof.
In my case at least there wasn't even a mouse cursor on screen, and the
fact that nothing was written to the journal for about 10 hours before
I rebooted would seem to indicate everything was dead. I should have
tried an ssh from my laptop but was too impatient to get the system up.
