Ubuntu – Desktop shows a white or black background instead of wallpapers

backgroundnautilus

After the upgrade from 12.10 to 13.04 my desktop background turns black after I try to set a image for that. How to fix it?

This is my desktop screen:

I tried this and it worked!

gsettings set org.gnome.settings-daemon.plugins.background active true

The following line pasted into a terminal did recover the background image for me:

gsettings set org.gnome.settings-daemon.plugins.background active true

Hope that helps you too...

I had the same exact problem, and it's covered by this bug in Launchpad:

The solution that worked for me, was to open dconf-editor, and set the following to active:

org.gnome.settings-daemon.plugins.background.active

That is, clicking "org" -> "gnome" -> "settings-daemon" -> "plugins" -> "background" and clicking the checkbox "active."
