title: 'Configure GNOME Screen Locking'
description: |-
In the default GNOME3 desktop, the screen can be locked
by selecting the user name in the far right corner of the main panel and
selecting <b>Lock</b>.
<br /><br />
The following sections detail commands to enforce idle activation of the screensaver,
screen locking, a blank-screen screensaver, and an idle activation time.
<br /><br />
Because users should be trained to lock the screen when they
step away from the computer, the automatic locking feature is only
meant as a backup.
<br /><br />
The root account can be screen-locked; however, the root account should
<i>never</i> be used to log into an X Windows environment and should only
be used to for direct login via console in emergency circumstances.
<br /><br />
For more information about enforcing preferences in the GNOME3 environment using the DConf
configuration system, see <b>{{{ weblink(link="http://wiki.gnome.org/dconf") }}}</b> and
the man page <tt>dconf(1)</tt>.
