I am using ubuntu 14.04 64-bit. (All my packages were up-to-date as of
about 1 week ago.) My hardware is an Acer C720 (Intel graphics). The
symptoms of the problem is the display completely stops updating, except
the mouse cursor continues to move. Clicking and any keypresses have no
effect. The system remains in this state for about 15-60 seconds, then
it recovers and goes back to normal.

The problem most commonly happens when using chrome or chromium to do
any kind of intesive hardware-accelerated rendering. Typically a youtube
video or and HTML5 game with lots of animations. The problem tends to
happen during periods of high CPU usage.
