Bug description:
Saucy updated just updated to 3.11.0-8 from -7. Ran for a while then
external monitor froze. Normally have built-in netbook screen off.
Systems settings displays said external monitor "unknown display" and
wouldn't run it. Normally reports it as Coby electronics co. ltd 40"
(?) max resolution 19201080x1080 I run it at 1360x768, 15.5" diagonal.
Rebooted later without external monitor, plugged it back in and
running normally now.
