<title>Configure automatic logout</title>
|
|
|
|
<p>User sessions that have been idle for a specific period of time can be
|
|
ended automatically. You can set different behaviour based on whether the
|
|
machine is running from a battery or from mains power by setting the
|
|
corresponding <sys its:translate="no">dconf</sys> key, then locking it.</p>
|
|
|
|
<note style="warning">
|
|
<p>Keep in mind that users can potentially lose unsaved data if an idle
|
|
session is automatically ended.</p>

<p>You can run <cmd>gsettings range</cmd> on a key for a list of values which
|
|
you can use. For example: </p>
|
|
|
|
<screen>$ <input>gsettings range org.gnome.settings-daemon.plugins.power sleep-inactive-ac-type</input>
|
|
enum
|
|
'blank' # blanks the screen

'shutdown' # starts a standard shutdown procedure

'hibernate' # hibernates the system
|
