I have the same problem. It just started out of the blue a few weeks ago. I assume after some update as I regularly accept updates. Ubuntu 14.04 LTS Intel Core i5-3320M CPU on Lenovo Thinkpad T430s 64-bit. System doesn't completely freeze because I can move between fields in the minaturized windows by pressing tab and can respond to some options. Only way out seemed to be hard reboot, until I was shown a temporary fix: cntrl alt F1 to get to a terminal log in with username and password unity --replace <enter> cntrl alt f7 to return to the desktop but top menu bar did not return had to shut down from the terminal sudo shutdown -h now
