ConsoleKit2 is a framework for defining and tracking users, login sessions, and seats. Its function is to support multiuser setups. It also works for a single user, but offers no benefits compared to existing methods. 
To launch an X session with ConsoleKit, append the following to the
exec statement in
exec ck-launch-session dbus-launch --sh-syntax --exit-with-session openbox-session
This starts Openbox with proper environment variables so it and its children are able to use ConsoleKit.
- Do not nest ConsoleKit sessions by calling one from another, or you will break ConsoleKit.
- In particular, since SLiM reads
~/.xinitrc, you should make sure not to run
No display manager
If you are not using a display manager, but starting your window manager via the
startx command, or from inittab.
If ConsoleKit is not working (
ck-list-sessions command showing active = FALSE), you should start your window manager using the bash_profile method: Xinit#Autostart X at login.
Install AUR and AUR.
If you use
/etc/pam.d/mdm, comment out
session required pam_systemd.so and restart
mdm. Additionally append
session optional pam_ck_connector.so nox11 if you have AUR installed.
Tips and tricks
Use D-Bus for power operations
dbus-send --system --print-reply --dest="org.freedesktop.ConsoleKit" /org/freedesktop/ConsoleKit/Manager org.freedesktop.ConsoleKit.Manager.Stop
dbus-send --system --print-reply --dest="org.freedesktop.ConsoleKit" /org/freedesktop/ConsoleKit/Manager org.freedesktop.ConsoleKit.Manager.Restart
dbus-send --system --print-reply --dest="org.freedesktop.ConsoleKit" /org/freedesktop/ConsoleKit/Manager org.freedesktop.ConsoleKit.Manager.Suspend boolean:true
Hibernate (suspend to disk):
dbus-send --system --print-reply --dest="org.freedesktop.ConsoleKit" /org/freedesktop/ConsoleKit/Manager org.freedesktop.ConsoleKit.Manager.Hibernate boolean:true
Hybrid Sleep (suspend + hibernate):
dbus-send --system --print-reply --dest="org.freedesktop.ConsoleKit" /org/freedesktop/ConsoleKit/Manager org.freedesktop.ConsoleKit.Manager.HybridSleep boolean:true
This method assumes that you are given permission to shut the system down via PolicyKit. The default group for this is
wheel. To change this, edit
/etc/polkit-1/localauthority.conf.d/50-localauthority.conf as root.
Running several applications from ~/.xinitrc
If several applications are to be executed from
~/.xinitrc, not all of these will have ConsoleKit environment variables set. In the following example, only children of Compiz will be able to properly use ConsoleKit, but children of xterm will not.
xterm & exec ck-launch-session compiz ccp
Typically, this can be an issue when for example using Compiz standalone and some other application launchers, (gnome-do, kupfer, gmrun, xbindkeys, etc.) since children of the application launcher will not be able to use ConsoleKit. A dirty workaround is to have the entire session started by a second script, e.g.
~/.xstart. Do not forget dbus-launch, it is likely that you will need it too:
exec ck-launch-session dbus-launch ~/.xstart
xterm & thunar & compiz ccp
Do not forget to make
$ chmod +x ~/.xstart
To see whether everything is started correctly:
It should show at least one session like this one:
Session18: unix-user = '1000' realname = 'Your Name' seat = 'Seat1' session-type = active = TRUE x11-display = ':0' x11-display-device = '/dev/tty2' display-device = '/dev/tty1' remote-host-name = is-local = TRUE on-since = '2011-11-16T12:01:50.104764Z' login-session-id = '7'
Consolekit blocks active TTY
Configure init to start ConsoleKit on an unused TTY, for example:
/usr/bin/openvt -c 63 -f -- /usr/sbin/console-kit-daemon --no-daemon &
See  for details.
Inactive session when launching X on same TTY
keeptty flag to startx or xinit , for example:
startx -- -keeptty

Replacing ConsoleKit with systemd-logind
Remove references to
See Session to check the status of your user session.
