[Nix-dev] Background images of desktop managers

[Tomasz Czyż]

Shouldn't the wallpaper be the user/session setting rather than system
setting?

Looks like kde, gnome, xfce way of doing this seems to be more natural,
user changes the wallpaper in his session.

Personally, I'm using awesome window manager and I use it with xfce session
so I have all other goodies that awesome is not offering. For all other
cases I think this should be implemented on the user space.
