[ubuntu] Mousepad stopped working

I'm ruing (limping would be a better verb...) Ubuntu 14.04 on my Asus X205T (there are lots of things i need to fix...) Yesterday the updater installed some stuff and asked to restart, I said later. The next time I started up, the mousepad doesn't work at all. Tried rebooting, apt-get update, and looked for a solution here, but didn't find anything that worked. I am a newbie (or just really lazy).
