Comment 0 for bug 914773

There are two issues.

Compiz has a memory leak so it expands to take up all memory plus swap (12 + 4 gig)

Unity shows a blank screen and does not come up with a login prompt, only the mouse pointer is displayed.

ctl+alt F1 works so you can get into a console and create the attached bug report. This was after killing vviewer and before restarting lightdm

I was running KVM and vviewer as well and killed vviewer but still did not get get login screen
Killed compiz which freed the memory still did not get login screen
had to restart lightdm to get back into Unity and restart everything.
