Public bug reported:
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.
