Public bug reported:
On my Thinkpad T450s, the touchpad stops working after sleep. I used to restart
it with the rmmod/modprobe psmouse sequence, but after software updates today
even that isn't working right (the touchpad comes back forgetting any
customized settings)
It'd be nice if this core problem were just fixed so the touchpad worked after
sleep.
