[SOLVED] Screen breaks up, checkerboard like.

Without having the same specific hardware it is hard to provide help.  It's not clear if the problem is driver related.  Your system currently uses the nouveau drivers which are generally ok.

I'd begin by noting the time the problem begins and checking the logs for a specific time period while the problem is evident.

Code:

journalctl --since hh:mm:ss --until hh:mm:ss
