  <title>Cambiar a pantalla de bloqueo</title>

  <p>The <em>lock screen shield</em> is the screen that quickly slides down when
  the system is locked. The background of the lock screen shield is controlled by
  the <sys>org.gnome.desktop.screensaver.picture-uri</sys> GSettings key. Since
  <sys>GDM</sys> uses its own <sys>dconf</sys> profile, you can set the default
  background by changing the settings in that profile.</p>

<steps>
  <title>Estabelecer a chave org.gnome.desktop.screensaver.picture-uri</title>
  <item xmlns="http://projectmallard.org/1.0/" xmlns:its="http://www.w3.org/2005/11/its" xml:id="dconf-profile-gdm">
    <p>Cree o perfíl <file its:translate="no">gdm</file> que contén as seguintes liñas:</p>
    <listing its:translate="no">
      <title><file>/etc/dconf/profile/gdm</file></title>
      <code>user-db:user
system-db:gdm
file-db:/usr/share/gdm/greeter-dconf-defaults</code>
    </listing>
    <p><input its:translate="no">gdm</input> é o nome dunha base de datos <sys its:translate="no" xref="dconf">dconf</sys>.</p>
  </item>
  <item><p>Cree unha base de datos <sys>gdm</sys> para as preferencias a nivel de maquina en <file>/etc/dconf/db/gdm.d/<var>01-protector de pantalla</var></file>:</p>
  <code>[org/gnome/desktop/screensaver]
picture-uri='file://<var>/opt/corp/background.jpg</var>'</code>
  <p>Substitúa <var>/opt/corp/background.jpg</var> coa ruta ao ficheiro de imaxe que qeure usar como fondo da pantalla de bloqueo.</p>
  <p>Os formatos admitidos son PNG, JPG, JPEG e TGA. A imaxe será escalada se é reciso para axustarse á pantalla.</p>
  </item>
  <item xmlns="http://projectmallard.org/1.0/" xml:id="dconf-update">
    <p>Actualizar a base de datos do sistema:</p>
    <screen><output style="prompt"># </output><input>dconf update</input></screen>
  </item>
  <item><p>Debe pechar a sesión antes de que os cambio a nivel de sistema se apliquen.</p>
  </item>
</steps>

<p>A seguinte vez que bloquee a pantalla, a nova pantalla de bloqueo mostrará o fondo. Por diante mostrarase a hora, data e o día da semana actual.</p>

<section id="troubleshooting-background">
  <title>Que pasa se o fondo non se actualiza?</title>

  <p>Asegúrese que executa a orde <cmd its:translate="no">dconf update</cmd> para actualizar as bases de datos do sistema.</p>

  <p>No caso que o fondo de pantalla non se actualice, tente reiniciar <sys>GDM</sys>.</p>
