ALl of a sudden today, my keyboard stopped working.
I'm using a macbook (2,1)

Everything else works fine, my trackpad etc. The keyboard just doesn't work, lights on caps won't light up, and I can't type anything in ubuntu.
I'm using a different computer to type this at the moment.

Any ideas on how to fix it ??
It's as if it's not loading any keyboard drivers or something.

Thanks

I'm on 7.10
