Public bug reported:
Binary package hint: xserver-xorg
X crashed after many hours of uptime, mostly sitting idle. No idea what
specific action of mine triggered it. The screen went black, then it
appeared that X was trying and failing to restart. Eventually ubuntu's
friendly "X is not working, would you like to try low graphics mode"
dialog appeared. I do have compiz enabled, but no screensaver.
INCIDENTALLY: On this same machine I have often encountered lockups
after many hours of uptime, but I've never managed to get a stacktrace
or anything interesting in Xorg.0.log, so it's been hard to file a bug.
When X locks up, no keyboard input has any effect: killall -9 Xorg is
the only thing that will kill it. Also changing VT frequently results in
lockups.
