<desc>Prevent the user from logging out and from switching a user.</desc>
</info>
<title>Disable user logout and user switching</title>
<p>Preventing the user from logging out is useful for special kind of GNOME
deployments (unmanned kiosks, public internet access terminals, and so on).</p>
<note style="important">
<p>Users can evade the logout lockdown by switching to a different user. That
is the reason why it is recommended to also disable <em>user switching</em>
when configuring the system.</p>
</note>

<screen>
[org/gnome/desktop/lockdown]
# Prevent the user from logging out
disable-log-out=true
# Prevent the user from user switching
disable-user-switching=true
</screen>
</item>
<item>

<file>/etc/dconf/db/local.d/locks/lockdown</file>:</p>
<screen>
# Lock user logout
/org/gnome/desktop/lockdown/disable-log-out
# Lock user switching
/org/gnome/desktop/lockdown/disable-user-switching
</screen>
</item>
