Just a quick update to this bug: the issue persists with unity
6.6.0-0ubuntu1 and compiz 1:0.9.8.2+bzr3377-0ubuntu1. In the last few
weeks I have not been able to reproduce this issue when using only the
internal monitor, but it is 100% reproducible when an external monitor
is connected. After the freeze has occurred, you can disconnect the
external monitor, but the internal monitor changes from the frozen image
to a black screen. It is possible to issue 'sudo killall Xorg' in tty1
and this brings you back to lightdm, but it kills all open windows and
unsaved documents, so doesn't really help. The issue can also be
reproduced using the guest session.

So just to summarize the steps to reproduce this crash:
- I have a dell mini 9 with an external monitor attached
- within a few minutes of normal usage the image on the screen will freeze (100% of the time)

(to speed up the last step you can eg open nautilus, browse to
/usr/share, left mouse down on the handle of the overlay scrollbar,
whilst holding the left mouse button down you can now make circle
movements with your mouse which will cause nautlius to scroll up and
down rapidly - this will cause the image on the screen to freeze within
10-60 seconds.)
