Unless I'm missing something, that changes the desktop wallpaper. I want to change the wallpaper of the login screen. I went to Kcontrol > System Administration > Login Manager > Administrator mode > Background and changed the "Picture" field to the picture of my choice. However, after my choice wallpaper loads, the Sabayon Blue themed wallpaper loads on top of it. Is there away to remove this Blue themed wallpaper (while keeping the SL prompt)?
EDIT: Solution Found!
There are two wallpapers loading on my system: One managed by the KDE control center, and one that loads on top of it. (possibly loaded by the sabayon logon screen?) This second wallpaper is /usr/share/backgrounds/login.png. By overwriting this file with the image of your choice will put it up when you log on, although changing the one in the KDE control center is still advised, as it still shows for a moment.
