<p>See the <cmd>org.gnome.desktop.background.picture-uri</cmd> gsettings
key. Note that <app>GDM</app> uses its own DConf profile. To change settings in
this profile, place a keyfile in <file>/etc/dconf/db/gdm.d</file> and run
<input>dconf update</input>. Here is an example keyfile that could be stored as
<file>/etc/dconf/db/gdm.d/corp-login</file>:</p>
<code>
[org/gnome/desktop/background]
picture-uri='file:///opt/corp/background.jpg'
</code>
<note>
<p>Note that these DConf key files are slightly different from gsettings
override files.</p>
