Description Scott Worley 2012-09-29 10:17:35 EDT
Description of problem:
Ejecting USB key using file manager by pressing eject icon next to USB key. 
Other applications open were firefox with three tabs and geany editor.
Even though screen was completely corrupted I observed eject of usb key notification at bottom of screen.
I was able to shutdown by clicking on upper right, guessing where mouse was and clicking alt-shutdown.

Additional info:
