In 20.04, I was trying out the desktop/background pictures and decided that I didn't like any of them.
There doesn't seem to be an obvious way to go back to "blank"?
I mean - I could create a flat black (my preference) in gimp and choose that as my background image - but surely resetting the desktop to "nothing but flat colour" shouldn't require that much work?
gsettings set org.gnome.desktop.background picture-uri ''
should do the job. – PRATAP May 17 '20 at 22:01gsettings set org.gnome.desktop.background primary-color blue
followed by above command. – PRATAP May 17 '20 at 22:03
