I've been using Linux for over 10 years and just downloaded 12.04 to my wife's laptop. It looks good but I can't find a way to slow the cursor down (yes, I have gone to System Settings and they are as slow as possible). This is on a System 76 Pangolin laptop with the pad.

If you're using a separate wireless mouse try unplugging the usb dongle and plugging it back in. That has worked for me.
