Some how I have changed something such that the command line:
gconftool-2 -t string --set /desktop/gnome/background/picture_filename 
/usr/share/backgrounds/images/other.jpg

does not change my background any longer.

Has someone come across this before?

How can I change gnome back to ALL default settings?
