--- Comment #2 from Walther Pelser <w.pel...@web.de> ---
Yesterday I reported a similar bug to openSUSE.
https://bugzilla.suse.com/show_bug.cgi?id=1154535, sddm cant start wayland.
maybe it is the same problem.
I was asked to report it to bugs.kde.org.
OS: openSUSE-Tumbleweed current
Plasma-Version 5.17
QT-Version 5.13.1
The problems began with the latest updates of plasma on 2019-10-16
This is the text of the description:
Sddm can start only x-session
Blackcreen when sddm tries to start wayland or fullwayland. Reboot necessary.
Systemdjounal shows: kernel kwin_wayland[6442]: segfault at 10 ip
00007f4adc4c0c30 sp 00007ffe7192ff08 error 4 in
libKF5WaylandServer.so.5.63.0[7f4adc49b000+60000]
See attachment systemd backtrace.txt
I tried everything, but could not repair this. There are a lot of
customizations maybe there could be a connection.
When I start an x-session and execute in a terminal: env GDK_BACKEND=wayland
QT_QPA_PLATFORM=wayland dbus-run-session /usr/bin/startplasma-wayland wayland
is starting.
