Before doing a HD installation, I did 3 or 4 Live FD’s (both 32 bit & 64). In every one, including the HD installation, the instruction told me to use “No wallpaper”, if I wanted a simple color as desktop background. Unfortunately, the “no wallpaper” option was nowhere to be found. Todo nada.
My solution as a workaround, was to use the paint program to create a PNG file named “black-1024×768.png”. The picture file was entirely black pixels, nothing else. I copied it into the /usr/share/wallpaper directory, where it became accessible to the wallpaper selection routine. I selected it, and – tah-dah! An entirely black desktop background.
It is best you provide the wallpaper app version apt policy wallpaper-antix
and the desktop session you are using (if rox-icewm or space-icewm or other) so that the developer can figure out how to fix this issue, or if it was fixed in a more recent version than the one installed on your system.
After selecting “No wallpaper”, you need to select the color (even if the default is already set to black), and then apply. That is how it worked for me.
The “No Wallpaper” option is only available if you are not running an icon manager (not a space- or rox- session).
This is because there is not command line option in spacefm / rox pinboard to set only a colour as the background.
