"End current session" as only option

Hello all, I have installed MX-15 Linux (I think I learned about it here), that is Debian based. I haven't used it so much yet (main install using openSUSE). Following the announce of 14.0.4 I have tried to dist-upgrade, which worked well (appart of Grub2 overwriting my mbr as usual) and MX-15 now has 14.0.4. However, I can't shutdown from TDE (anymore? I think I could before, but I am not 100% sure). I have checked what settings I identify "(offer shutdown options" is checked, "allow shutdown" is set to "everybody") but after a right click + Log out <user> all I'm offered is to "End current session". To shutdown or restart I must use the command line and get root. Thierry
