  <title>Lock the screen when the user is idle</title>

  <p>You can make the screen lock automatically whenever the user
  is idle for some amount of time. This is useful if users
  may leave their computers unattended in public or unsecure
  locations.</p>

  <steps>
    <title>Enable automatic screen lock</title>
    <include href="dconf-snippets.xml"
             xpointer="xpointer(/*/*[@xml:id='dconf-profile-user'])"
