Bug 443490

SUMMARY

This only applies on Wayland since under Xorg it's possible to set it up using a few commands on boot.

Currently, if you have an external screen with a touch screen digitizer, it will automatically assign it to the internal/integrated one. In my case it's an Asus ZenBook Duo with a Screenpad (a 1080x515 creen right above the monitor) but this probably applies to folks using fancy Cintiq like devices. This will not work since it's not the correct display. I'd like to have an option in the Display KCM to map the touch screen to the correct display or, if even possible, to autodetect it (GNOME somehow manages to do it in both Wayland (tested on TW) and Xorg (avoiding stuff like 398487, tested on Pop_!OS)).

STEPS TO REPRODUCE
1. Connect external touch enabled display
2. Try to navigate the applications in that display
3. See the inputs happen on the integrated display

OBSERVED RESULT

Touch screen input happens on the incorrect display

EXPECTED RESULT

Touch screen input happens on the correct display, either by default without requiring additional set up by the user or by exposing an option to modify the behavior through the KCM
