I found that my Lenovo laptops did not always get the mousepad right when coming out of sleep or hibernate. After a bit of research I found that a modprobe remove and insert of the psmouse kernel module did the trick.

To automatize this you can insert a file in the systemd control structure to fix the problem yourself (if you are experiencing it). Below is a block of code. Save this to a file in /lib/systemd/system-sleep/touchpad

#!/bin/sh PATH=/sbin:/usr/sbin:/bin:/usr/bin case "$1" in pre) #code execution BEFORE sleeping/hibernating/suspending # unload touchpad driver /usr/sbin/modprobe -r psmouse ;; post) #code execution AFTER resuming # reload touchpad driver /usr/sbin/modprobe psmouse ;;
esac exit 0
