I have tried it now. I went to the TTY, stopped SDDM, and then ran this commandWell, have you tried starting Plasma Wayland from command-line? the plasmawayland.desktop file contains the following command:
/usr/local/lib/libexec/plasma-dbus-run-session-if-needed /usr/local/bin/ck-launch-session /usr/local/bin/startplasma-wayland
Code:
/usr/local/lib/libexec/plasma-dbus-run-session-if-needed /usr/local/bin/ck-launch-session /usr/local/bin/startplasma-wayland
So I guess while the command exists, it doesn't seem to be working right for some reason.
