Bug Description

Lenovo Thinkpad T480
Ubuntu 18.04.03

On resume (e.g. after closing and then opening lid), the track pad will no longer allow me to scroll, tap or drag.

The problem can be temporarily resolved by entering the following commands into the terminal...

sudo modprobe -r psmouse && sudo modprobe psmouse
