Every time I close my laptop's lid, and open it later, touchpad stops working and I can't make it work otherwise, but only by rebooting. I have also downloaded touchpad-indicator software, and disabling/enabling touchpad through it, but it didn't help also.
Mouse works fine, even when this happens, but not touchpad. What could be the problem?
I found a solution from ubuntuforums: Removing psmouse module and readding it:
sudo modprobe -r psmouse
sudo modprobe psmouse
This could be the same issue discussed here: Ubuntu 17.10: Lid closing disables touchpad, how to fix?
If so, upgrading to a newer Ubuntu version should fix it. Ubuntu 16.04 is quite old now, why not go with 19.04?
It might help changing from wayland to xorg: How do you switch from Wayland back to Xorg in Ubuntu 17.10?. (Originally proposed by Joe: Ubuntu 17.10: Lid closing disables touchpad, how to fix?) It worked for me on 22.04 LTS.
