TLDR:
Windows 11 v24H2 and beyond will have Recall installed on every system. Attempting to remove Recall will now break some file explorer features such as tabs.

I’m not sure how it works for KDE and sddm but on gdm it is possible to copy the monitors.xml config file to a certain directory to fix that. After doing so, the login and lock screen settings are synced between the desktop environment and display manager. Not sure how to do it for sddm but I’m sure there’s a way, maybe a script with the correct xrandr commands could solve that.
Edit: monitors.xml, not x11.conf
Yeah, that works sometimes, but the way to fix it seems to change every time I have had to do it. And I have been using Wayland lately and haven’t found a good way to do it that works with the latest versions.
I was curious about this and found this KDE forum post that might help. Looks like you don’t even need a script.
