Public bug reported:

Binary package hint: xserver-xorg-video-intel

I've had what appears to be this crash a couple of times in natty now.
Today I was going through a fullscreen presentation in LibreOffice and
on one slide change the whole server crashed. I don't know if this is
related to #781983 as I get constant screen corruption consisting of
misplaced bits of the screen and the trace seems to indicate an errant
memory access. The same system was working just fine under maverick.
This is a Lenovo X61 laptop that I usually use with an external monitor.
The screen artifacts happen with the monitor connected or disconnected
but are very prominent with it disconnected. The crashes seem to have
only happened after it has been disconnected so there could be some
xrandr involvement.

I've installed xserver-xorg-video-intel-dbg but the backtrace in the log
still doesn't seem to have symbols:
