I am running Ubuntu GNOME 15.10 with GNOME 3.18, and I have set an image as my desktop background, it has a white bit around it, however when I set it to be "Spanned" on my desktop in the GNOME Tweak Tool it is put in the middle with two big black bits next to it:

enter image description here

So how can I make those black bits go white? How can I change the background colour to white (well, the black bits that is, that's what it would have been called on Unity)?

  • Don't create a new "colours" tag, as we already have a "colors" tag! :P

  • Me neither, but we don't need two tags for the same word!

    @ByteCommander: Why not just get rid of the American one then so that we only have one proper one? >:P

Use gsettings to set the color white (#FFFFFF) and a solid fill.

gsettings set org.gnome.desktop.background primary-color "#FFFFFF"
gsettings set org.gnome.desktop.background secondary-color "#FFFFFF"
gsettings set org.gnome.desktop.background color-shading-type "solid"
