            Bug ID: 428760
           Summary: Remap touchscreen to laptop integrated panel on
                    display configuration change
           Product: KScreen
           Version: 5.20.2
          Platform: Neon Packages
                OS: Linux
            Status: REPORTED
          Severity: normal
          Priority: NOR
         Component: kded
          Assignee: kscreen-bugs-n...@kde.org
          Reporter: aldo-pub...@laposte.net
  Target Milestone: ---

I have a laptop with a touchscreen.
When using it alone (without an external monitor), the touchscreen works as
expected.
But when I plug an external monitor and do multi-monitor, then the touchscreen
area is mapped to the whole visual area (not just limited to laptop integrated
panel), which is awkward since the user expects that the pixel being interacted
with is the one under the finger.

Please, make it so the touchscreen input is always mapped to the laptop panel,
whatever happens !

For information I use X11 Plasma.

Also it seems that the command "xinput --map-to-output <touchpad_id>
<screen_id>" works for fixing the touchscreen manually, so it would be enough
if kded would run this command on every display change (maybe the user would
have to declare what screen is the laptop panel and what pointing device is the
touchscreen, if this cannot be automated?).
