Had this happen with stock nvidia-177 installed with ubuntu and now with 180.11 downloaded and installed from nvidia website.
The display will normally freeze for a few seconds, although the mouse still moves. Then the mouse also freezes for up to 30 seconds, with about a 1/2 to 1 second interval where it will update. I have not had any hard freezes on this; it usually recovers anywhere from 2 to 7 minutes later.
