[Bug 1322275] Re: lightdm sessions started by dm-tool lock (or a session locker) never get closed

 

Hi Sergio,

Yes I did mean /etc/xdg/xdg-xubuntu/lightdm/lightdm-gtk-greeter.conf ,
thanks for that.

Here's what I have for x-1-greeter.log:

--------
(lightdm-gtk-greeter:2212): Gtk-CRITICAL **: gtk_container_foreach: assertion 'GTK_IS_CONTAINER (container)' failed

(lightdm-gtk-greeter:2212): Gtk-CRITICAL **: gtk_container_foreach:
assertion 'GTK_IS_CONTAINER (container)' failed

(lightdm-gtk-greeter:2212): Gtk-CRITICAL **: gtk_container_foreach: assertion 'GTK_IS_CONTAINER (container)' failed
g_dbus_connection_real_closed: Remote peer vanished with error: Underlying GIOStream returned 0 bytes on an async read (g-io-error-quark, 0). Exiting.
--------

Unfortunately, I don't know what these entries mean. The .old file
contains exactly the same messages, except for having a different PID
listed.

Also, it might be worth mentioning that I'm on Xubuntu 14.04, and have
these indicator related entries unchecked in my Session and Startup GUI,
under Application Autostart:

Indicator Application
Indicator Power
Indicator Sound

I unchecked these as a previous troubleshooting step, and left them
unchecked since they'll be started anyway by the indicator panel applet.

Title:
  lightdm sessions started by dm-tool lock (or a session locker) never
  get closed

Status in Light Display Manager:
  New
Status in lightdm package in Ubuntu:
  Confirmed
Status in upstart package in Ubuntu:
  Confirmed

Bug description:
  dm-tool lock starts a new lightdm greeter (for unlocking) and a new
  logind session. After unlocking the greeter disappears, but the logind
  session never closes. loginctl session status c24 reports something
  like:

  c24 - lightdm (103)
             Since: Thu 2014-05-22 18:38:27 CEST; 30min ago
            Leader: 7872
              Seat: seat0; vc8
           Display: :1
           Service: lightdm-greeter; type x11; class greeter
             State: closing
            CGroup: systemd:/user/103.user/c24.session
                    └─7907 init --user --startup-event indicator-services-start

  This results in an accumulation of stale lightdm sessions after using
  e.g. a session locker for a while.

  I get this issue on a freshly installed and fully updated Xubuntu
  14.04.
