Title:
Detected a hung GPU, disabling acceleration.
Status in “linux” package in Ubuntu:
Expired
Bug description:
Kubuntu 13.04
Thinkpad T520
Bios: automatic (i.e. detect support for descrete graphics, though does not
seem to detect anything)
$uname -a
Linux fk1304 3.8.0-27-generic #40-Ubuntu SMP Tue Jul 9 00:17:05 UTC 2013
x86_64 x86_64 x86_64 GNU/Linux
Screen will regularly (typically 1-3 times a day) freeze for a few
moments, then the acceleration is disabled.
I have seen this happen in different situations:
When switching between folders in dolphin
When scrolling in FF
When switching between desktops (I use kwin set up with a 9 desktops grid, no
Compiz)
When running a java app and a vmware virtual machine
I have not found a certain way to make this happen, though it seems to
be related to spikes of heavy activity.
