Description of problem: Currently trying to launch kwin_wayland (inside X11) fails because it cannot find the Qt platform plugin. Installing the package qtwayland5 solves the problem and makes kwin_wayland start. The qtwayland5 package should be suggested by kwin. Note that launching kwin_wayland in DRM mode still fails with "FATAL ERROR: could not find a backend". On Graesslin's blog post https://blog.martin-graesslin.com/blog/2016/07/why-does-kwin_wayland-not-start/ it says the platform/backend plugin is missing, but I don't know in which package it could be Version-Release number of selected component (if applicable): 5.7.1-2 How reproducible: always Steps to Reproduce: 1. in a virtual terminal, enter: export $(dbus-launch) kwin_wayland --xwayland 2. this should open a blank kwin_wayland window; instead, without the qtwayland5 package installed, it will exit with the following error message This application failed to start because it could not find or load the Qt platform plugin âwaylandâin ââ. Available platform plugins are: wayland-org.kde.kwin.qpa, eglfs, linuxfb, minimal, minimalegl, offscreen, xcb. Reinstalling the application may fix this problem.

Please test next kwin package.
Just installed after manually removing qtwayland5, and now the dependency is installed automatically, so now it's ok. Regarding the missing DRM backend, I see that the only available Wayland backends are Virtual, X11 and Wayland (nested, I guess); supposedly the missing one is the file KWinWaylandDrmBackend.so, which I didn't find anywhere with urpmf. Does it have another name, or is it not built at all? Regardless, since the Plasma Wayland session isn't supposed to be in Mageia 6, it's fine if the DRM backend isn't yet available; but if it's just a build mistake or some other oversight, I'd like to have that as well
drm backend should be available on next kwin rpm.
Thanks, but the backend is still missing. $ ls /usr/lib64/qt5/plugins/org.kde.kwin.waylandbackends KWinWaylandVirtualBackend.so* KWinWaylandWaylandBackend.so* KWinWaylandX11Backend.so*
you should have /usr/lib64/qt5/plugins/org.kde.kwin.waylandbackends/KWinWaylandDrmBackend.so in the new kwin rpm.
Don't upgrade your system,neoclust you breaked kwin with added kdecoration to requires while it don't exist in Cauldron. A requested package cannot be installed: kwin-5.7.1-5.mga6.x86_64 (due to unsatisfied kdecoration)
