I was able t reproduce the situation and quickly switch to tty9 before the lock up occured. I am still unable to type anything in any tty, however I see the following errors printed to the screen:
BUG: soft lockup - CPU#0 stuck for 22s [apport-gpu-error 2777] and BUG: soft lockup - CPU#1 stuck for 22s [compiz-error:2290] It will do this for every logical cpu. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1009585 Title: [Dell Vostro 460]: System is unresponsive after Unity login screen.
