<title>User Switching</title>

<p>
|
|
<em>User switching</em> is a method of running more than one session at a time on a <link xref="seat">seat</link> and switching between them.
|
|
Only one session can be used at a time.
|
|
The session is switched by contacting the display manager using D-Bus and calling the one of the following method on the Seat object:
|
|
</p>
|
|
<list>
|
|
<item>
|
|
<p>
|
|
SwitchToGreeter - A greeter session is started. This allows the user to authenticate for a new session or authenticate to return to their current session.
|
|
</p>
|
|
</item>
|
|
<item>
|
|
<p>
|
|
SwitchToUser - If there is a session for the given user then it is switched to, otherwise a greeter is started.
|
|
</p>
|
|
</item>
|
|
<item>
|
|
<p>
|
|
SwitchToGuest - If a guest session is active it is switched to, otherwise a guest session is started.
|
|
</p>
|
|
</item>
|
|
</list>
|
|
<p>
|
|
Switching is performed using <em>virtual terminals</em> in the kernel.
|
|
Each session has a separate display server and the selected session is activated by changing the active virtual terminal.
