Description John Veness 2025-05-22 13:07:25 UTC 
SUMMARY
Bug 455619 reported no ability to disable a touchscreen in Plasma. A fix was provided (kcm_touchscreen) for Wayland, but not for X11.

STEPS TO REPRODUCE
1. Login to a Plasma X11 session
2. Wish to disable a touchscreen e.g. to stop accidental presses
3. Run System Settings
4. Look for "Touchscreen" KCM, in order to disable touchscreen (as exists in Wayland)

OBSERVED RESULT
Find a "Touchscreen" entry, but that actually opens Touchscreen Gestures (kcm_kwintouchscreen). Don't find a way to disable the touchscreen in System Settings.

EXPECTED RESULT
Find a Touchscreen KCM to disable the touchscreen, in addition to Touchscreen Gestures.

ADDITIONAL INFORMATION
A workaround is to run "xinput list" to find your touchscreen ID, then "xinput disable <id>", but that's not very user friendly.

I think you need the "Wacom Tablet" KCM for this. Can you use that to do this?
Comment 2 John Veness 2025-05-22 16:09:30 UTC 
I have no Wacom Tablet KCM, but I do have a Graphic Tablet KCM, if that's the same thing. Unfortunately the touchscreen doesn't show up in there.

Our X11 session is feature-frozen, so we are not going to add this. Sorry.
