Warning: Arch Linux only has official support for logind [1] and systemd. When using ConsoleKit, please mention so in support requests.
Note: While Consolekit is no longer maintained upstream, the fork ConsoleKit2 is under development. [2]

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. [3]

## Installation

Install the consolekitAUR and polkit-consolekitAUR packages.

## Configuration

### ck-launch-session

To launch an X session with ConsoleKit, append the following to the `exec` statement in `~/.xinitrc` e.g.:

    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.

Display managers like GDM, LXDM and SLiM start ConsoleKit automatically with each X session.

Note:

- 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 `ck-launch-session` there.

### No display manager

If you are not using a display manager and ConsoleKit is not working (i.e. `ck-list-sessions` command showing `active = FALSE`), you should start your window manager using the bash_profile method: Xinit#Autostart X at login.

### Desktop environments

LightDM can be used as a login manager.

## Tips and tricks

### Use D-Bus for power operations

The factual accuracy of this article or section is disputed.

Reason: Content must be revised for `ConsoleKit2` and other developments (Discuss in Talk:ConsoleKit)
Note: Using ConsoleKit2's D-Bus methods for suspend, hibernate, and hybrid sleep requires pm-utilsAUR.

Shut down:

    dbus-send --system --print-reply --dest="org.freedesktop.ConsoleKit" /org/freedesktop/ConsoleKit/Manager org.freedesktop.ConsoleKit.Manager.Stop

Restart:

    dbus-send --system --print-reply --dest="org.freedesktop.ConsoleKit" /org/freedesktop/ConsoleKit/Manager org.freedesktop.ConsoleKit.Manager.Restart

Suspend:

    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.

## Troubleshooting

### 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.

    ~/.xinitrc

    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:

    ~/.xinitrc

    exec ck-launch-session dbus-launch ~/.xstart

    ~/.xstart

    xterm &
    thunar &
    compiz ccp

Do not forget to make `~/.xstart` executable.

To see whether everything is started correctly:

    $ ck-list-sessions

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 [4] for details.

### Inactive session when launching X on same TTY

Specify the `keeptty` flag to startx or xinit [5], for example:

    startx -- -keeptty

See also Xorg#Session log redirection.

## Replacing ConsoleKit with systemd-logind

Note: systemd-logind requires booting with systemd to be functional.

Remove references to `ck-launch-session` from `~/.xinitrc`.

See Session to check the status of your user session.
