Bug#667684: (no subject)

[Markus]

No it happened again. dmesg was not very verbose this time. It just 
says: NVRM: GPU at 0000:02:00.0 has fallen off the bus.

But from /var/log/Xorg.0.log I could get these lines:

[  5371.634] (EE) NVIDIA(0): Failed to determine chip graphics capabilities

Anyway I still had working ssh connection.
