Bug Description
screen locks up with mouse cursor moving
Started somewhere around beta1.
In my case triggered reliaebly by running NX client (background or foreground) but only to machines on LAN.
Unfortunelty problem was mis-identified by ubuntu-bug as an duplicate therefor reported manually.
Detailed crash report attached
intel_gpu_top showed:
render busy: 70%:
bitsream busy: 100%
blitter busy: 100%
GAM: 100%:
No other tasks appeared and GPU got very hot.
Update:
Using backported from Quantal Kerenl (3.4.0-1.x) solves the problem.
