How to disable the touchscreen in Ubuntu 21.04?
I faced a problem after a couple of days that my malfunctioned touchscreen was on unexpectedly, despite setting MatchIsTouchscreen "off" at /usr/share/X11/xorg.conf.d/40-libinput.conf
How to make it disabled just like Ubuntu 20 and the older versions?
So after hours of searching a solution to that is keep that configuration MatchIsTouchscreen "off" and to make Xinput runs by default again to apply that configuration.
To disable Wayland:
- open the file:
sudo nano /etc/gdm3/custom.conf - uncomment (remove # from):
WaylandEnable=false
