I am using Ubuntu 14.4.3 and really like the default cyan background.
I want it to not change with time. However, I cannot find the file in /usr/share/backgrounds. I was hoping to construct an image background and install that. Does anyone have a solution for this?
(edited to add the following)
Here is a shot of the one I want
gsettings get org.gnome.desktop.background picture-uri. See the dupe. – Jacob Vlijm Sep 06 '15 at 05:20
