I was happily running Xubuntu 11.10 with xfce4, but ran into the problem of not being able to update things, since it was no longer supported. I upgraded to 12.04 LTS with only moderate pain, and got most everything running.
However, I had set up my system using wallpapoz to show a different wallpaper on each of my 4 desktops. Whatever code in 11.10 allowed this to happen seems to have been removed or otherwise made unavailable. Does anyone know how to restore this capability. I do not want to use KDE, Gnome or Unity for a display manager - Xfce4 and lightdm do just what I need.
It would be instructive to know what was changed to cause this wallpaper capability to no longer function, but what I really want is just to make it work again.
