I want to use a custom login back ground on Kubuntu and I have the settings pointing to the picture I want but it just shows up as black on the login screen.Any ideas why?
Could you show the theme xml file ? What theme are you using as a template ?
Same kind of problem from the Kubuntu Forums: http://www.kubuntuforums.net/showthread.php?56248-This-SHOULD-be-simple
The default Horos theme is using: wallpaper="Horos".
The documents ( K > Applications > Help > Control Center Modules > Login Screen ) are telling that it should be: file="background.svg". The background could be a pixel file: file="my-wallpaper.png" etc.
