Is there solution using a utility or folder shortcuts that would keep the active desktop wallpaper/background the same in KDE and Gnome/Unity. (Changing the background in one desktop would also change the other desktop's wallpaper)
I use both desktops because they both serve me better for different tasks, and i'd like to match LightDM login background for KDE as well. Regardless of that it would just be nice to accomplish this for personal consistency and unity.
This is no heart breaker if it's not possible. It's just an extra couple of steps when I want to change my background.
note: in KDE I disable ksplash
