Comment 13 for bug 987498

This is a Compiz issue - it doesn't seem to be related to my video drivers at all. Running 12.04LTS on HP 8570w (Nvidia K1000 - just in case there's a pattern), this also happened on my last HP 8560w (also nvidia). However - this problem seems to appear relatively randomly, I've found that bouncing Compiz = instant relief.

As with others here - my screens lock up (laptop or my external monitors), the mouse will still move, key combos to launch an xterm work (ctrl+alt + t) as do the other ttys but I cannot click on any existing open window to move it or type in it (only in new term windows). Killing compiz and restarting it = instant relief however this is not a fix..... The problem comes back in a short time. This often occurs under load - with many browser tabs up (FF) and with VMware WS running etc. So this issue makes running this itteration of Ubuntu almost unusable..... Please address this.
