Let me explain: I have a funny setup -- no systemd, no dbus (still, Debian buster, and X). At some point in time, the browser (firefox) brought in dbus via some dependencies. Annoyed, I killed dbus -- and poof, all browser instances were gone. If I inhibit dbus from starting, the browsers run fine without it. My hunch is that they keep an open socket conection to the dbus and die on SIGPIPE or some such. So yes, if all those apps are sharing "the" session dbus, possibly started by whoever came first *and* the logout takes the session dbus down, this might be an explanation. Now don't ask me why I try to avoid that ;-) Cheers -- t
