Bug Description

I need help further diagnosing it, but today (Friday October 10th) I installed the mornings updates to interpid, and upon rebooting GDM login screen will not recognize (zero response) my keyboard (both external and built in on my laptop) or mouse (both external and trackpad).

I can however use ctrl+alt+f1 to get to a terminal and interact with the computer that way.

I've also double checked to see if there are any more updates that might fix this problem, and apt-get upgrade doesn't give any result.
