[solved] After upgrade to KDE6, black screen under Wayland

Hello,

I've updated my whole system and therefore switched to KDE6. If it's work well under X11, I'm unable to start a Wayland session. After several seconds of a totally black screen, it reverts to SSDM.

I've read several threads about similar problems but despite apparent similarity, situation doesn't look the same. I don't have a NVIDIA graphic card, KVM is active. I've uninstalled xf86-video-intel.

I've seen a lot of these messages in journalctl:

 
qt.qpa.xcb: could not connect to display
qt.qpa.plugin: From 6.5.0, xcb-cursor0 or libxcb-cursor0 is needed to load the Qt xcb platform plugin.
 qt.qpa.plugin: Could not load the Qt platform plugin "xcb" in "" even though it was found.
This application failed to start because no Qt platform plugin could be initialized. Reinstalling the application may fix this problem.
Available platform plugins are: eglfs, linuxfb, minimal, minimalegl, offscreen, vkkhrdisplay, vnc, xcb, wayland-egl, wayland.

Here is the full journalctl output:

Thank you for any advice.
