Description Recesvintvs 2020-02-19 17:48:28 UTC
If I start a session with one user, do some activity and then close the session, and then I start a new session with a different user, I can see, in htop, several instances of the process "agent" that belong to the former user, and which path is /usr/libexec/geoclue-2.0/demos/. By the name I guess it has to do with geolocation, which I have not activated for that user (not sure if for any), so I guess it must come active by default. I don't think that's a nice privacy policy even in Linux and KDE dont have backdoors.
Ok, let's center and not divagate too much... The point is that I believe that one user's processes should be shut down, or killed if they refuse to terminate gracefully, once the user logs out.

There have been similar reports even since 10 years ago, but I'm not sure if those are exactly like this one. In one, it seemed related to encryption or Akonadi; in the other, affected the login process; this one I report doesnt seem to produce any malfunction in anything (the processes just "sit" there wasting resources). but if you consider this is a duplicate, feel free to mark it as such, but then please reopen the one that says it's resolved/fixed.

Sorry, I'm on Gentoo, using OpenRC instead of Systemd, and I'm afraid I don't know of an equivalent command for loginctl. Can you suggest one?
Comment 3 Recesvintvs 2020-02-19 20:36:17 UTC
Ok, forget about the former comment. I found it on Gentoo's fora.

# ck-list-sessions
Session2:
        unix-user = '1004'
        realname = '(null)'
        seat = 'Seat1'
        session-type = 'unspecified'
        session-class = 'user'
        session-state = 'active'
        active = TRUE
        x11-display = ':0'
        x11-display-device = '/dev/tty7'
        display-device = ''
        remote-host-name = ''
        is-local = TRUE
        on-since = '2020-02-19T15:06:53.014753Z'
        login-session-id = '2'
        XDG_RUNTIME_DIR = '/var/run/user/1004'
        VTNr = '7'
Comment 4 Recesvintvs 2020-02-20 17:16:13 UTC
Hi. I wanted to add some info.
I didn't know that Consolekit was deprecated nor that Elogind could be used in non systemd systems, but since now Im aware of it, I uninstaled CK and are now using Elogind. So, here you have the exact info that you asked (don't think it's necessary to run it as root, but just in case doing it as a "foot user" some info were missing):

# loginctl show-session
EnableWallMessages=no
KillUserProcesses=no
RebootToFirmwareSetup=no
IdleHint=no
IdleSinceHint=0
IdleSinceHintMonotonic=0
BlockInhibited=handle-power-key:handle-suspend-key:handle-hibernate-key:handle-lid-switch
DelayInhibited=sleep
InhibitDelayMaxUSec=5s
UserStopDelayUSec=0
HandlePowerKey=poweroff
HandleSuspendKey=suspend
HandleHibernateKey=hibernate
HandleLidSwitch=suspend
HandleLidSwitchDocked=ignore
HoldoffTimeoutUSec=30s
IdleAction=ignore
IdleActionUSec=30min
PreparingForShutdown=no

Comment 5 David Edmundson 2020-02-20 17:33:09 UTC
If it's just the stuff from the shared dbus-daemon changes

toggling this to yes

KillUserProcesses=no

should fix it

And where should I make that change (average user here with modest knowledge)? loginctl only shows info but doesnt allow to edit it, right? Also, the available commands for loginctl don't sound like if any was a sort of editing tool:

activate           kill-session       lock-session       show-session       unlock-session
attach             kill-user          lock-sessions      show-user          unlock-sessions
disable-linger     list-seats         seat-status        terminate-seat     user-status
enable-linger      list-sessions      session-status     terminate-session  
flush-devices      list-users         show-seat          terminate-user

New information was added with comment 6; changing status for inspection.
Comment 9 Recesvintvs 2020-03-10 22:09:44 UTC
Thanks Cristoph.

Yes, the one who "needsinfo" is me, hehe. As soon as I can try the solution provided by D. Edmundson I'll mark this bug as resolved if said proposed solution remedies the problem. But I have no clue of where I must set "KillUserProcesses=yes" That's why I didn't anything for more than 15 days. I'll try to do some Google search by myself if I can recall it the next days.
Comment 10 Christoph Feck 2020-04-09 21:14:18 UTC
The "KillUserProcesses=no" is from systemd, see Google's results.
