Bug#756988: desktop-base: please provide a background for GDM 3 and its screen lock mode

[Martin-Éric Racine <martin-eric.racine@iki.fi>]

Package: desktop-base
Followup-For: Bug #756988

While 8.0.1 in principle introduced new background images for GDM (Thanks!), GDM still shows its default gray background.

Running 'gksudo -u Debian-gdm gnome-tweak-tool' confirms that lines.xml and lines-lockscreen.xml are correctly configured in the dconf keys, so I'm guessing that the problem is somewhere else e.g. hard-coded paths in the gdm3 package.
