screen locked up while changing workspaces (cursor still moves)

[Dave Russell]

Unsure if it's compiz or unity...

Screen froze, the workspace changer is still visible in the centre of the screen, nothing obvious in logs, cursor still moves.

Can switch to VT and run commands.

This is the first time it's happened since updating to 12.04

.xsession-errors looks like it might have something useful

this line

intel_do_flush_locked failed: No space left on device

from the attached .xsession-errors file makes me believe it is in fact a duplicate of bug #977804

[Daniel van Vugt (vanvugt)]

Good point Steffen. Though the description seems to describe bug 815996. Hopefully the two are related.
