Comment 170 for bug 980519

I also got this bug recently. At random clicks on random programs (Chrome, web site links, etc), I would get logged out (black screen that flutters constantly between the login until I click on the mouse, move the mouse, type something, or in some cases wait long enough, in which a stable login screen will appear to allow me to log back in). However, I was able to fix this issue by not using unity. Instead I installed gnome and logged out and back in with gnome (I'm using the class with no effects version). Hope this helps.
