I feel like this should be simple, but it’s eluding me. We have several shared PCs in the house, used by all members of my family. They are all running Manjaro with KDE Plasma as the desktop. What we would like is, after a period of inactivity, to automatically log the user out and return to the login screen.
The problem we are having now is that User A stops using the computer and walks away. Later, User B wants to use the computer but needs to first logout User A, then re-login as User B.
Furthermore, I see where the options in KDE Plasma exist to automatically put the system into sleep/suspend mode after a period of inactivity. But this is tied to the user. How can I configure this at the system level, so that it always sleeps after a timeout, regardless of who is logged in (or if the system is at the login screen).
