STEPS TO REPRODUCE 1. Install the latest KDE Neon unstable edition (Plasma 6 RC2) in QEMU 2. Log in with the Wayland session 3. Go to Display configuration and change the Resolution to 1920x1080 OBSERVED RESULT The user gets a black screen and only the cursor appears. After a few seconds the old resolution is restored and everything is back to normal (in the old resolution). EXPECTED RESULT The user gets no black screen and is able to change to his preferred display resolution (the same experience as with the X11 session). SOFTWARE/OS VERSIONS Linux/KDE Plasma: (available in About System) KDE Plasma Version: 6.0.80 KDE Frameworks Version: 6.0.0 Qt Version: 6.6.1 Kernel version: 6.5.0-15-generic (64-bit) Graphics Platform: Wayland Tested in a Virtual Machine (in QEMU v4.0.0) with the following specs: Processor: 2 × Intel® Core™ i3-4150 CPU @ 3.50GHz Memory: 3.8 GiB of RAM Graphics Processor: llvmpipe Manufacturer: QEMU Product name: Standard PC (Q35 + ICH9, 2009) System version: pc-q35-6.2
ADDITIONAL INFO: This used to work in the previous KDE Neon unstable ISO release, hence the "regression" tag. The X11 session is not affected by this bug.
Can reproduce using Virtual Machine Manager and running KDE Neon Unstable on QEMU/KVM
Can confirm. There's more to this though: - switching to a higher resolution mode works - this only happens with legacy modesettings with atomic modesetting it works fine
I just tested this and this works now changing resolution up and down
