loginctl terminate-session $XDG_SESSION_ID leaves niri running (but detaches the screen)

[wucke13]

I'd like to have a generic way of terminating my session (as I"m using multiple WM, one of them niri). I think, the generic command for that would be loginctl terminate-session $XDG_SESSION_ID (assuming systemd-logind is used). That works in so far, as in that it detaches the session and throws me back to the display manager. However, upon next attempt to start a niri session, I instead get a warning that a niri session is already runnig.

And indeed, systemctl --user status niri reveals that the session was never ended, but it seemingly lost access to the screen. I think, it would be sensible if the loginctl command above had the same effect as running niri msg action quit --skip-confirmation.

What likely plays into this behavior: for my user I have lingering systemd user instances enabled.

@wucke13 Hi, did you find any solution or workaround. I use both hyprland and niri, mostly niri but still have hyprland. I want the logout command in my wlogout to be generic so that it works with both. Most of other commands like lock, shutdown, reboot are generic, just logout is not working.
I also use SDDM as my display manager. When I use Super+M, it cleanly exit and goes back to display manager screen, but when I use loginctl terminate-session, it exits from niri but goes to black screen and not to SDDM screen. I think, it is same issue that it doesn't exit from niri-session.

Yes, sort of:

XDG_SESSION_ID="$(systemd-run --user --scope --slice=session.slice printenv XDG_SESSION_ID)"
case "$XDG_CURRENT_DESKTOP" in
  # if niri is running, terminate it properly
  niri)
    systemctl --user stop niri.service || echo "niri stop failed"
  ;;
  *)
    echo "no special treatment"
  ;;
esac
# finally, give up this session
loginctl terminate-session "$XDG_SESSION_ID"

Bumping this issue.
It would be great if loginctl terminate-session "$XDG_SESSION_ID" resulted in niri exiting cleanly.
When I run it, I’m returned to the display manager, but starting a new niri session then warns that niri is already running.
Workaround: loginctl terminate-user "$USER" does stop niri for me.
