I'm not sure which packages are involved. Reproducible: Always Steps to Reproduce: 1. click on kde menu 2. click on bottom-right submenu (left-arrow icon) 3. click on "change user" Actual Results: The screen is locked. Exaclty as if i had choosen "lock" from the same submenu. There's no button/icon for "create new user" or "change user" or whatever. Just the plain, standard, lock. Expected Results: I want to create another session, for another user. That is to have two x11 sessions i could switch between. Typicall, i guess, using, control-alt-f7 and f8. I'm using openbox instead of kwin, but that doesn't change anything. I'm using 'lxdm' as display manager. I tried with 'sddm', and in this case, it works. I'm not sure of the implication of this.
That would mean lxdm does not create a proper logind session for you, either by misconfiguration on your part or a bug in the package. LXDM upstream is dead for many, many years.
Misunderstood your main problem from $summary at first.
FWIW, the Gentoo integration of elogind and systemd was done for simplicity and no multi-seat as defined by freedesktop[1]. It is true that no lxdm coding exists to do more work than the simple PAM calls listed there. [1] https://www.freedesktop.org/wiki/Software/systemd/writing-display-managers/
