Hi Community,

How can I (as root) log off a user from the KDE desktop when accessing the SSH console remotely? Is there a special command that can be placed on the console?

A quick google search presents this askubuntu question which lists several mostly gnome-specific options, but includes:

qdbus org.kde.ksmserver /KSMServer org.kde.KSMServerInterface.logout 0 0 0

for logging out of kde (presumably still works with Plasma 5, but test to be sure). Use the --address parameter to qdbus to specify the user's dbus session.

That question also lists sudo pkill -u username, which kills all processes owned by the specified user (you can specify which signal to use to send to their processes just like with the kill command).

This stackexchange question has an additional command which should work on systemd systems using logind, regardless of desktop session used.
