Using Ubuntu on my laptop ... my trackpad pointer has suddenly stopped working. I'm sure that a reboot will fix it, but it's tricky performing a reboot when you don't have a working mouse.
So I've plugged in a USB mouse for now, but I was wondering ... what's the best way to reset the trackpad on Ubuntu?
@francis I've tried several things from that page and nothing has worked yet. The question is old, my hardware and OS are newer, so it's not clear anything there will work for me.
