--- Comment #4 from Zamundaaa <xaver.h...@gmail.com> ---
In 5.21 plasmashell and some other apps generally crash on Wayland when you
disable an output, it should be unrelated to the display problems (and is fixed
in 5.22).
The hang is almost certainly KWin triggering a kernel bug.

Then the displays failing to configure properly is most likely a duplicate of
https://bugs.kde.org/show_bug.cgi?id=433107. To confirm some more information
would be good:
What GPU(s) are in the laptop?
What's in ~/.local/share/sddm/wayland-session.log?
Ideally test with the environment variable
QT_LOGGING_RULES="kwin_*.debug=true;kwin_libinput.debug=false"
set for the session and upload the file afterwards from a X11 session (the file
gets overwritten if you log into wayland).
The output of drminfo both in the working X session and when it doesn't work on
Wayland could also be useful (not necessarily necessary though).
