Comment 116 for bug 1365695

I don't know if the bug I reported 1373968 , is the same as 1365695 or not,
so I reported mine as a separate bug. My symptoms are that system boots as
normal to a Ubuntu GUI login screen. After entering my password the login
screen is replaced by an Ubuntu background (14.04 LTS in the bottom left
corner of the left hand monitor (I have a dual monitor setup)). And then no
further updates to the screen. The right hand monitor is inactive the
whole time.
