I've been using ubuntu for quite some time now but still have problems every now and then sadly. I disabled my mouse/touchpad by accident(like the idiot i am ) when trying to fix the jumping cursor error(while typing the cursor randomly jumps and messes up lines of text or randomly highlights and deletes stuff). I disabled it through the mouse and pointer program.

I've found a few solutions online but none have helped my problem yet. I'd rather not reinstall ubuntu if i don't have too, especially since i didn't make a backup(if i fix this i'll be sure to fix that.

Anyway i have a lenovo g580 with ubuntu 13.04 installed any help is appreciated, and greatly needed.
