I can confirm that nvidia-graphics-drivers-331 331.20-0ubuntu0.0.2 is working correctly, and I don't observe any artifacts after suspend.
Unfortunately I cannot test nvidia-graphics-drivers-331-updates 331.38-0ubuntu0.0.1, because it is still in NEW state: https://launchpad.net/ubuntu/precise/+queue?queue_state=0 ** Tags removed: verification-needed ** Tags added: verification-done-precise -- You received this bug notification because you are a member of DX Packages, which is subscribed to unity in Ubuntu.

Switching to a VT and back to X can potentially solve freeze issues, but corruption may result. [Test Case] Suspend/Resume many times with nvidia graphics and see if the problem happens. [Regression Potential] This is already in Trusty. -- Perform regular suspend, either from system menu or close laptop lid, when system resuming from suspend, it will freeze. Switch to VT and back to X can solve freeze issue, but the screen are gabled and some character rendering are strange, however whole system can perform usual task. found affected graphics: gf108m gf117m gk107glm To manage notifications about this bug go to: https://bugs.launchpad.net/hwe-next/+bug/1210077/+subscriptions -- Mailing list: https://launchpad.net/~dx-packages Post to : dx-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~dx-packages More help : https://help.launchpad.net/ListHelp
