Public bug reported:
I upgraded to ubuntu 14.04 Trusty Tahr a couple of days ago. There were
a few errors/bugs which I automatically reported but I ended up with a
usable OS and mostly everything worked fine. Suddenly the display on
monitors turned haywire. I have a 2 monitors set up and both monitors
started displaying random gray stripes on top of the actual applications
that were open on the screens. Both the screens were covered in these
gray stripes which were moving around randomly as well.
I don't know what package or software/application is responsible for the
behavior. It was the first time it happened on ubuntu (14.04, I had been
been using ubuntu 12.04 for almost 2 years prior with same hardware) but
I have seen this happen on Fedora 20 with a 2 monitor setup multiple
times.
I have a camera photo of what the screens looked like but the
"printscreen" option on the keyboard failed to save the data on the
screens.
Let me know if any further information is desired.
