  <p>You can display extra text on the login screen, such as who to contact for
  support, by setting the
  <sys>org.gnome.login-screen.banner-message-enable</sys> and
  <sys>org.gnome.login-screen.banner-message-text</sys> GSettings keys.</p>

  <steps>
    <title>Display a text banner on the login screen:</title>
    <include href="dconf-snippets.xml"
      xpointer="xpointer(/*/*[@xml:id='dconf-profile-gdm'])"
      xmlns="http://www.w3.org/2001/XInclude"/>
    <item><p>Create a <sys>gdm</sys> keyfile for machine-wide settings in
    <file its:translate="no">/etc/dconf/db/gdm.d/01-banner-message</file>:</p>
      <code its:translate="no">[org/gnome/login-screen]
banner-message-enable=true
banner-message-text='<input its:translate="yes">Type the banner message here.</input>'
</code>
    </item>
    <include href="dconf-snippets.xml"
      xpointer="xpointer(/*/*[@xml:id='dconf-update'])"
      xmlns="http://www.w3.org/2001/XInclude"/>
  </steps>

  <note>
    <p>There is no character limit for the banner message. <sys>gnome-shell</sys>
    autodetects longer stretches of text and enters two column mode.</p>
    <p>The banner message cannot be read from an external file.</p>
