When attempting to change the resolution of my display in a Wayland Plasma session, the setting in System Settings: Display and Monitor: Display Configuration is not obeyed. When changing the resolution in the Resolution drop down menu and then selecting "Apply", nothing happens. Reproducible: Always Steps to Reproduce: 1. Log into Wayland Plasma session 2. Navigate to System Settings: Display and Monitor: Display Configuration 3. Change resolution in the drop down menu 4. Click "Apply" Actual Results: Nothing happens Expected Results: The display resolution changes to the selected resolution I am only able to change the resolution of a Wayland Plasma session by configuring a resolution for Grub using kernel mode-setting. This resolution is kept throughout the boot sequence and into a Wayland session. I am using VMWare Workstation 12 Pro version 12.1.1 with the open-vm-tools (from the VMWare github repository) version 10.0.0 and the vmwgfx DRM driver built into the Linux kernel (version 4.6.4). When logging into an X11 Plasma session, the display resolution is constantly updated to fit the VMWare Workstation window on the host. I am using Gentoo with Plasma 5.7.1, KDE Frameworks 5.24.0, and KDE Apps 16.04.3. Here are the results of emerge --info kde-plasma/systemsettings: https://gist.github.com/ehermes/b34efdfadbefa23d5b087c9fdd8d0835
Updated to Plasma 5.7.2, problem persists.
Expected. KScreen's wayland backend so far only supports positioning, not mode-setting.
> Expected. KScreen's wayland backend so far only supports positioning, not mode-setting. Sebastian, is there any changes? I tested Kubuntu 17.10 in KVM and find that I can't change screen resolution in Plasma Wayland session.
No changes so far.

I think this bug should be mark as RESOLVED FIXED
I can change screen resolution under plasma 5.12.1 Wayland but the setting is lost when I restart session/computer.
> I think this bug should be mark as RESOLVED FIXED Just tested Kubuntu 18.04 in QEMU, still can't change screen resolution under Wayland session. Resolution from kscreen configuration is also not applied on login.
@RussianNeuroMancer Which Plasma version did you test? (You can find it in kinfocenter.)
Plasma 5.12.2 Frameworks 5.43.0 Qt 5.9.3
I think a wayland backend has recently been added, is this still a problem?

Is this issue still reproducible with Plasma 5.16 or 5.17 ? On my system, in wayland I can't change the resolution at all, but this might be a different issue. I have a HDipi display.
Here I changed my screen resolution from 1080p to 720p and the new setting was preserved after I restart Plasma session and after reboot. Operating System: Arch Linux KDE Plasma Version: 5.17.0 KDE Frameworks Version: 5.63.0 Qt Version: 5.13.1
