fyi, this works on ubuntu 12.04 to change the gdm login screen background image:
http://smashingweb.ge6.org/change-the-background-of-gnome-3-gdm-login- screen/ quoted: """ # su - gdm -s /bin/bash $ dbus-launch This command will print DBUS_SESSION_BUS_ADDRESS and DBUS_SESSION_BUS_PID. We need to export them $ export DBUS_SESSION_BUS_ADDRESS=unix:abstract=/tmp/dbus-Jb433gMQHS,guid=fc14d4bf3d000e38276a5a2200000d38 $ export DBUS_SESSION_BUS_PID=4283 Check to see if dconf-service is running and if not, start it like this $ /usr/lib/dconf/dconf-service & Wallpaper $ GSETTINGS_BACKEND=dconf gsettings get org.gnome.desktop.background picture-uri $ GSETTINGS_BACKEND=dconf gsettings set org.gnome.desktop.background picture-uri "file:///usr/share/backgrounds/gnome/SundownDunes.jpg" You will need to point to a file where the gdm user has permission to read, not in your home directory. """ then as root restart the gdm service. for precise I had to "chown gdm.gdm /var/lib/gdm/.config -R" first, as root owned that not the gdm user, so the gdm user couldn't write the file. The resulting /var/lib/gdm/.config/dconf/user file is binary so can't just edit the config file with a text editor as per 4 decades of UNIX /etc conventions.
