This evening I was trying to find the correct way to set the GDM3 background-picture. I wanted to set it to my own image file journey-login-background.jpg. I thought I share the results.
Obviously the way to set the GDM login picture has changed a lot in Wheezy. Formerly it has been configured by the desktop-base package in: /usr/share/gdm/greeter-config/10_desktop-base (/gdm3/10_desktop-base in the source-package) The line: /desktop/gnome/background/picture_filename /usr/share/images/desktop-base/login-background.svg pointed to the login-background image. A second line was used to set how the picture is shown: /desktop/gnome/background/picture_options zoom This doesn't seem to work anymore. Another way to set the login-background was to use similar lines in /etc/gdm3/greeter.gconf-defaults /desktop/gnome/background/picture_filename /usr/share/images/desktop-base/login-background.svg /desktop/gnome/background/picture_options zoom This also doesn't work for me. Now with GDM3 the login-background obviously is set by GSettings. There seem to be three possibilities: 1.) Add these lines in /etc/gdm3/greeter.gsettings [org.gnome.desktop.background] picture-uri='file:///usr/share/images/desktop-base/journey-login-background.jpg' picture-options='zoom' In the last line you can choose between "zoom", "scaled" and "stretched". After changing the file you have to run: dpkg-reconfigure gdm3 to make the changes permanent. This worked for me. Source: http://www.stderr.nl/Blog/Software/Gnome/Gnome3-Gdm3-Background.html 2.) Set the background in the terminal. I didn't try it, but obviously it can be done this way. su - su - gdm -s /bin/bash `dbus-launch | sed "s/^/export /"` GSETTINGS_BACKEND=dconf gsettings set org.gnome.desktop.background picture-uri "file:///usr/share/images/desktop-base/journey-login-background.jpg" Please note that you must specify a file which user "gdm" has permission to read. For instance, user "gdm" cannot read files in your home directory.

Or, if you are just too lazy for that: - delete /usr/share/images/desktop-base/login-background.svg - create a symlink with the same name that points to the picture you want to use: ln -s /usr/share/images/desktop-base/journey-login-background.jpg /usr/share/images/desktop-base/login-background.svg (I used this as workaround when I created my theme.)
