Howto Restart KDE 6 Plasma

Currently KDE6 Plasma (bottom bar, window decorations, black background) sometimes vanish after I wake up my laptop and Plasma needs to be restarted. Forget about restarting SDDM or KDM or other greeters like in the old times, they are running on a different screen (Alt+F1 KDE and Alt+F2 SDDM) now. Also with this command you don’t have to login again and all windows stay open.

systemctl --user restart plasma-plasmashell

Now everything should be back.
