Comment 0 for bug 1386695

I'm testing the new development branch (Vivid Vervet), which currently has the Utopic kernel 3.16.0-23-generic installed (proposed repositories are enabled).

This problem might be a regression, and it has been reported

upstream:

https://bugs.freedesktop.org/show_bug.cgi?id=81136

Problem:

When I try to resume from hibernation the screen hangs and the GPU is locked. It cannot load the graphics properly.

Testing:

Unloading or blacklisting the nouveau driver and perform the following test, seems to indicate that the problem is nouveau:

# echo platform > /sys/power/disk
# echo devices > /sys/power/pm_test
# echo disk > /sys/power/state

Mainline:

The problem seems to be fixed in latest stable mainline kernel, for now
3.17.1-031701-generic (Utopic).
