is idle for some amount of time. This is useful if users
may leave their computers unattended in public or unsecure
locations.</p>
<steps>

<p>Create the key file
<file>/etc/dconf/db/local.d/00-screensaver</file> to provide
information for the <sys>local</sys> database.</p>
<listing>

<code>
# Specify the dconf path
[org/gnome/desktop/session]
# Number of seconds of inactivity before the screen goes blank
# Set to 0 seconds if you want to deactivate the screensaver.
