You have been subscribed to a public bug: I was using ubuntu 3.19.0.22 (15.04). On starting the computer, the login screen was displayed. I logged in and then shortly after the display appeared to crash (I have two monitors) bys displaying a bizarre black and white pattern. The system did not respond to ctrl-alt-del . Pressing one of the mouse buttons caused the display to revert to a regular Ubuntu background. I rebooted, but had the same problem. I then used the advanced login options to start up using kernel 3.19.0.15 and all appear to work OK.
