I have a problem with ubuntu 12.04 that started while using the fn and some of the f1...f12 keys on my keyboard. All of a sudden my computer starts to "press" volume up and directly afterwards "long-presses" either E or W. It will also make a few of my own key-presses not respond. I have absolutely no clue as to why it does this but it makes programming a pain.
Specifications: Ubuntu 12.04 Lenovo thinkpad T430
