|Plasma] Blank screen + pointer, SDDM error
#1
Hello,

I updated my freshly-received PinePhone Beta, which was working correctly. Then after restart I have only a black screen with KDE logo and a mouse pointer. I can connect via SSH.

I also tried lots of commands like "DISPLAY=0.0 startplasma-wayland -- vt1" or "DISPLAY=:0.0 kstart5 plasma-desktop", which give:
Quote:Failed to create wl_display (No such file or directory)
qt.qpa.plugin: Could not load the Qt platform plugin "wayland" 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, vnc, wayland-egl, wayland, wayland-xcomposite-egl, xcb.

Aborted (core dumped)


I reinstalled packages related to plasma, wayland, xorg, x11 or sddm. I also set my username instead of kde in the key Autologin.User in the file /etc/sddm.conf.d/00-default.conf. All this does not help.

Any ideas? Thank you.
