Hello to all readers Logout from KDE (Plasma 5.20.5) lasts more then 10 sec. This is abnormal as under Buster logout passed immediately (login screen: sddm or lightdm, does not matter) appeared just in time. If I log in as root (only under lightdm possible) there is no delay in logging out. Even creating a fresh new user same behavior. Any idea about the reason ? Herbert S.
