SUMMARY One display resolution out of all is available for selection from GUI to be applied in Plasma on Wayland: 1280 x 800, tested on laptop Dell latitude E4300.
EXPECTED RESULT: As many resolutions as the ones available on Gnome on Wayland.
Operating System: Fedora 33
KDE Plasma Version: 5.19.5
KDE Frameworks Version: 5.73.0
Qt Version: 5.15.1
ADDITIONAL INFORMATION: Resolutions available for selection from GUI to be applied in Gnome on Wayland: 1280 x 800, 1280 x 7200, 1024 x 768, 800 x 600.
the same for Dell XPS 9700 with 17" 4k screen. No option to select lower resolutions that are available in gnome wayland.
For resolutions that are "uncertain" a temporary change with confirmation dialog and timeout should be implemented to revert the changes if configuration is not confirmed as working.
