I'm running Ubuntu Studio 14.04 on my Macbook 3,1. It worked well until today. The internal keyboard doesn't work properly anymore. Most keys don't work at all, while a few produce the wrong characters. For example, the keys J, K and L produce the numbers 1, 2 and 3.
It's not a hardware issue, in Mac OS everything is still fine. My external keyboard also works correctly.
Can anybody help me?

I don't know why, but the problem was solved by pressing F6 twice.
FYI, this is because the keyboard has a number pad built in. F6 disables this, and means you can type your letters rather than numbers.
1Press the Caps Lock key. num. (F6) to activate the keypad.
