Edit these 2 files, if not exist create them. Note that DP-2 and DP-4 are examples. Find out which port your monitor connecting to by running xrandr. If rotate right is not right then change to left.

When you change to 2k Ultrawide

Out of curiosity, what happens if I need to change back to my “regular” 1440p? Will it break? Or how will SDDM handle that situation (mainly for curiosity sake).
oh that’s good to hear. I just hope that Wayland will be ready for gaming soon
On Wayland, SDDM it remembers resolutions per-screen, so that shouldn’t be a problem.
But it’s a manual process, so every time you change a screen’s resolution, you’ll need to re-sync the SDDM settings if you want them to remain in sync.
Once SDDM is brought into KDE, it might be possible to make it automatic, as long as you have only one user of course. If you have multiple users, it would either have to be manual again, or track only a single user’s configurations.
