I'm experiencing some strange keyboard behavior after rebooting my Ubuntu 12.04 box. I have a Microsoft ergonomic keyboard like this one. Previously, I was able to use the extra keys (e.g., the "Favorites" key) to do things like launch a terminal. Those keys are no longer registered by ubuntu at all.
Additionally, the keyboard lock LEDs (num lock, caps lock) do not light when I press the lock buttons, although they act correctly. That is, if I press caps lock, the caps lock LED does not come on but letters show up as capitals.
