Description Ralf Jung 2022-12-31 09:00:20 UTC

SUMMARY

I just updated my KDE (Debian testing) and there is a major regression: I can no longer select 1920x1080 as resolution for my internal screen. In fact I can no longer select any resolution except for the native 4k resolution.

This makes the system essentially unusable for me. Things still worked fine (under Wayland) before the update -- not entirely sure which version that was, I think 5.26.3?

Basically https://bugs.kde.org/show_bug.cgi?id=461168 is back, but in much worse form since now only the native resolution is available.

Created attachment 154951 [details]
kscreen-console bug

Full output is attached. There's an "xrandr --verbose" section in there, which strikes me as odd in a wayland session -- but it *does* list a lot of alternative resolutions, including the one I want to use. KScreen (the UI) does not offer it though.
