Weird screen settings on docking station

rated 0 times [ 0] [ 0] / answers: 1 / hits: 783 / 2 Years ago, sun, december 19, 2021, 4:52:12

When I set my Lenovo X220 Tablet onto the docking station where a 1920x1200 screen is attached via Display Port -> DVI, both the internal and the external screen show the greatest common resolution which is 1024x768.

I can then set the display settings within KDE, but that is rather time consuming. Is there a way to set up the displays correctly when the notebook is in the docking station? Os can I write a shell script that sets the displays correctly?

Using xrandr, I managed to write a script for it.

The main part is this:

case "$1" in

    on)

        xrandr --output "$internal" --auto

        xrandr --output "$external" --auto --right-of "$internal" --primary

        ;;

    off)

        xrandr --output "$internal" --auto --primary

        xrandr --output "$external" --off

        ;;
