I have been running Ubuntu 14 on two Dell monitors for a year - no problems.. A few days ago my monitors both showed only a scrambled pattern of lines. Yesterday I switched hard drives and installed Ubuntu 16 (just for the heck of it since I wanted to try 16 anyway). Everything seemed fine. Today it looks like the same problem just re-appeared. Just wondering- can this mean overheating of something or video card or what. Once it happens ( appears intermittent) I would not be able to run any diagnostics (?)
At the moment all is well but who knows when problem may reappear.
Any ideas.
