I changed my windowing system in ubuntu from wayland to xorg (for some app). I uncommented line WaylandEnable=false in file /etc/gdm3/custom.conf and rebooted the laptop. After this my touchscreen stopped working neither with lenovo pen nor with fingers.
I tried to change that file back and rebooted for a few times, but this didn't help.
Could someone help me and advice what to do to make the touchscreen works?
Laptop: Lenovo ThinkBook 14s Yoga G2 IAP
OS: Ubuntu 22.04.3 LTS

xev shows nothing when I try to touch screen.
evtest doesn't show anything like touchscreen:

I booted from "Lenovo Linux Diagnostics - Bootable CD" from official site. It said that touchscreen isn't supported on the laptop. Does it mean that problem with touchscreen is a hardware problem?
