I have this bug as well with a geforce GT 640M. To answer that question, it happens to me on both KDE (with compositing) and LXDE (no compositing) so compositing does not appear to matter.
Also, for me, kernel 3.9 works fine; the issue only appears on newer ones than that. Another report of what looks like the same bug: https://bugs.launchpad.net/ubuntu/+source/nvidia-graphics- drivers-319/+bug/1220865 -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to nvidia-prime in Ubuntu. https://bugs.launchpad.net/bugs/1210077 Title: Screen freeze and gabled after resume from suspend Status in “nvidia-prime” package in Ubuntu: Confirmed Bug description: Perform regular suspend, either from system menu or close laptop lid, when system resuming from suspend, it will freeze.
