Comment:
So this happens even when launching Plasma from SDDM? The .desktop file seems to come from upstream, so we really shouldn't have any issues due to it.

https://community.kde.org/KWin/Wayland#Start_a_Plasma_session_on_Wayland makes it clear that plasma wayland requires dbus-run-session, I'm curious about X11, though. Might be worth a bug report upstream, I'm asking about it on #kde.
