Public bug reported: 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).
