nvidia drivers, twinview and resume cause garbage on screen

[Christian Theune]

I just updated to oneiric and see a similar problem to #813343.

When either resuming or turning on two monitors with twinview (one works fine) I get garbage.

When trying to enable twinview I can still see the mouse and with a bit of luck get one monitor working again. Two doesn't.

I just noticed that the unity UI is still visible at this stage and I can press the window key and interact with unity. However, all windows are just displaying garbage but seem to work fine. Might be a compiz issue?
