Created attachment 188162 [details] screenshot of settings page in x11 warning: i am a teen (15) so i do not have much experience in writing formal things. SUMMARY Cant change resolution in KDE-plasma X11 and Wayland despite xrandr advertising multiple modes important note: This is done in a Qemu VM, both virtio and qxl has the same problem and i did not test the others. This has used to work and other older VM's that i have with older KDE versions still do. This is not an x11 bug! despite i am primarily showing x11 the same issue happens on Wayland too. STEPS TO REPRODUCE 1. Install arch linux in a regular way (arch wiki install guide), this includes networking 2. Update system and install plasma-desktop and select pipewire jack and ffmpeg media. 3. install and enable sddm and launch KDE OBSERVED RESULT The screen is locked to the resolution 1280 x 800 and the settings screen does not show alternatives to change, infact it removes the entire display configuration page leaving only nightlight (and compositor in the x11 session). installing gnome and/or other DE/gui's still have working resolution management on the same installation. checking (on the x11 session) xrandr says that the virtual screen actually does support different solutions. EXPECTED RESULT SOFTWARE/OS VERSIONS info center: Operating System: Arch Linux KDE Plasma Version: 6.5.4 KDE Frameworks Version: 6.21.0 Qt Version: 6.10.1 Kernel Version: 6.18.2-zen2-1-zen (64-bit) Graphics Platform: X11 Processors: 8 Γ AMD Ryzen 7 7800X3D 8-Core Processor Memory: 8 GiB of RAM (7.7 GiB usable) Graphics Processor: llvmpipe Manufacturer: QEMU Product Name: Standard PC (Q35 + ICH9, 2009) System Version: pc-q35-10.1 ADDITIONAL INFORMATION xrandr output: Screen 0: minimum 320 x 200, current 1280 x 800, maximum 8192 x 8192 Virtual-1 connected primary 1280x800+0+0 (normal left inverted right x axis y axis) 325mm x 203mm 1280x800 74.99*+ 5120x2160 50.00 4096x2160 50.00 3840x2160 60.00 50.00 59.94 1920x1440 60.00 2560x1080 50.00 1856x1392 60.00 1792x1344 60.00 2048x1152 60.00 1920x1200 59.88 1920x1080 60.00 50.00 1600x1200 60.00 1680x1050 59.95 1400x1050 59.98 1280x1024 60.02 1440x900 59.89 1280x960 60.00 1360x768 60.02 1280x768 59.87 1024x768 60.00 800x600 60.32 640x480 60.00 59.94
i realize now i forgot the expected result page, im sorry. the expected result is the get the fully functional settings page for display management in kde plasma on both Wayland and x11 and it should be able to change the resolution to all/almost all of the resolutions reported by xrandr
That looks like you simply forgot to install kscreen?
(In reply to Zamundaaa from comment #2) > That looks like you simply forgot to install kscreen? thanks, in prevous installations kscreen was installed with the plasma-desktop package. did something change?
Not that I know of, kscreen has been an "optional" dependency in Arch for a while.

I don't know. You'll have to ask Arch people about it, we don't do packaging here.
