I'm not sure how or why it happened. I can't recall modifying anything that had anything to do with the touchpad, but it recently stopped responding all together. Where would be the best place to start troubleshooting?

I thought it might be something in xorg.conf.. but I can't really tell. I've attached in in case there's something I can do with it to make it work.
