users, sessions, and seats present on a system. It
provides a mechanism for software to react to changes of any of
these items or of any of the metadata associated with them.

ConsoleKit provides a D-Bus API for programs to obtain information about the
users, sessions, and seats that are present on a system.
</p><p>
Please see the other sections of this manual for an introduction to
these concepts.
</p><p>
This API is not yet stable and is likely to change in the future.

For sessions with a <a href="#Session:x11-display"><code class="literal">x11-display</code></a> set (ie. graphical
sessions), it is up to each session to delegate the
responsibility for updating this value. Typically, the
screensaver will set this.
</p><p>However, for non-graphical sessions with a <a href="#Session:display-device"><code class="literal">display-device</code></a> set
the Session object itself will periodically update this value based
on the activity detected on the display-device itself.
</p><p>
This should not be considered authoritative.
