Comment 5 for bug 891838

Just a bit more information that might help resolve this issue.....

Dell XPS L501x (nVidia Video Card using proprietary driver (nVidia Post Release Updates)).

Suspend and Hibernate don't recover correctly - when using Gnome 3 the desktop comes up corrupted when waking up Suspend and Hibernation. Screen corruption matches what is described above.

When using Gnome (Classic) both Suspend and Hibernate work correctly.

When using Mate, only Suspend works correctly, and Hibernates shows a corrupt desktop (as discussed above) when started from Hibernate. I'll log a bug if it's not already a known problem.
