Has anyone tried to change the background image when using lightdm? Using the 'background' option in the lightdm-gtk-greeter.conf file is not giving the desired output.
Instead of the image, only a black background shows up. Is anyone else seeing this?

Look like the background image has to be in the right format
file /usr/share/backgrounds/spherical-cow/default/standard/spherical-cow.png
/usr/share/backgrounds/spherical-cow/default/standard/spherical-cow.png: PNG image data, 2048 x 1536, 8-bit/color RGBA, non-interlaced
it has to be ' 8-bit/color RGBA', using a .jpg or a 8-bit/color RGB .png gives you a black or red background.
Try opening your background image in gimp and select 'Layer -> Transparancy -> Add Alpha Channel' and export it to a .png
copy the .png to /usr/share/backgrounds/ and edit /etc/lightdm/lightdm-gtk-greeter.conf to point to the .png
then it should work
