Hi,
Here in experimental I suggest to use paintitblack wallpaper for our's experiments if possible.
Paintiblack wallpaper can be installed via apt-get or via dpkg.
If using apt=get you should edit siduction list and add:
deb
http://packages.siduction.org/base next main
Of course after doing this a apt-get update is required.
It is possible to use also dpkg but you need to download package first.
Thank you
