Description Ralf Jung 2022-10-29 16:49:44 UTC 
SUMMARY
My laptop has a 4k screen with max resolution of 3840 x 2160. However I usually prefer to run it in full HD resolution, 1920 x 1080. When using an X11 session, kscreen offers to configure the screen with that resolution, but under Wayland it does not -- I can pick 1920 x 1200, or 2560 x 1440, but I cannot select 1920 x 1080.

ADDITIONAL INFORMATION

Interesting, I have a screen with the same resolution and aspect ratio (on a 14" ThinkPad X1 Yoga), and the combobox offers me that resolution on Wayland.
Comment 2 Nate Graham 2022-11-01 14:03:28 UTC 
I'm using Fedora rather than Debian, so maybe some system library is newer on my system and that makes it work better?
Comment 3 Ralf Jung 2022-11-01 15:38:26 UTC 
On IRC I was told that this should fix my problem: https://invent.kde.org/plasma/kwin/-/merge_requests/3138.
Comment 4 Nate Graham 2022-11-01 15:44:04 UTC 
Ok cool. Can you check in Plasma 5.26.3 to see if the problem's fixed?
Comment 5 Ralf Jung 2022-11-01 15:50:55 UTC 
Once it is packaged in Debian I can check that, yeah...
Comment 6 Ralf Jung 2022-12-31 09:00:48 UTC 
Looks like unfortunately this bug is back, but in a worse form: https://bugs.kde.org/show_bug.cgi?id=463655
