Dear KDE-Community,

i have this problem:
I use my surface 3 in school as a teacher. I connect my surface to the beamer to show pupils things. At first i duplicated the screen on my surface, but the pupils can see what i do on my surface, so i made an extended monitor and mirror via screencast (vlc) only one window, which i want to show the pupils.
i do this via script:

Code: Select all

#!/bin/bash
xrandr --output eDP-1 --pos 2159x0 --mode 2160x1440 --scale 1x1 --primary --output DP-1 --pos 0x0 --mode 1024x768 --scale-from 2160x1440
xrandr --output eDP-1 --pos 2160x0 --mode 2160x1440 --scale 1x1 --primary --output DP-1 --pos 0x0 --mode 1024x768 --scale-from 2160x1440
xrandr --output eDP-1 --mode 2160x1440 --rate 48
xinput map-to-output "NTRG0001:01 1B96:1B05 Stylus stylus" eDP-1
xinput map-to-output "NTRG0001:01 1B96:1B05 stylus" eDP-1
xinput map-to-output "NTRG0001:01 1B96:1B05 touch" eDP-1
xinput map-to-output "NTRG0001:01 1B96:1B05 Stylus eraser" eDP-1
xinput map-to-output "NTRG0001:01 1B96:1B05 eraser" eDP-1
sleep 1
xrandr --output eDP-1 --mode 2160x1440 --rate 60


Don't be irritated the first two lines i need to change the position of the window, because otherwise my primary monitor (eDP-1) is black. But that's another problem.
If i extend my Monitor with this script, dolphin does not recognize my inputs with the finger via touch.
If i tap on an folder-icon in dolphin, it will me marked as selected, but i can't look in the folder with the tap-action. I have to use the mousepad or the stylus to do that, but that's annoying.
If i mirror the screen, everything works fine.
So what can i do, to avoid this behaviour in dolphin?
