In case your display arrangement or settings, e.g. when you have 3 screens and you are for some reason unable to reorganize them or change their settings, just reset your display settings:
For KDE Plasma:
rm -rf .local/share/kscreen
For GNOME:
rm -rf .config/monitors.xml
Then just log out and back in.
That’s it! Enjoy!

Thanks for linking to that, but did you try it yourself? I’d be VERY wary of implementing 5 year old KDE advice at this point. It’s change a LOT since then.
