when I start ubuntu 12.04 LTS every time the desktop background(wallpaper) appear black if I change it to a new wallpaper again after restart the the wallpaper vanished and black screen appear. what should I do?
Ubuntu 13.04 default wallpaper directory is "/usr/share/backgrounds/", Is this correct?
I wrote a code that can add pictures to the directory and create "contest/raring.xml".
But it's does not work. the wallpaper directory has many pictures but i can not choice any picture to wallpaper. "Right-click desktop" -> "Change Desktop Background" ,there only one black wallpaper!
I have list all options for wallpapers. When I long press the screen, the option has disappeared, and I now have a black background. I have gone into settings and tried to set it there, but though the wallpaper option is in it, it does not take, live or still. It happened when I installed the app Multipicture Live Wallpaper.
