My thinkpad touchpad problems are solved.
So, while I was sitting there and playing banjo, I thought it would be nice to have some some info of your device, or a crystal ball.
and while you’re at it, take a look at /var/log/messages if there are messages about psmouse .
If it looks like an interruption try:
sudo rmmod psmouse && sudo modprobe psmouse
Does this wake it up again ?
