This question already has an answer here:
I want to modify preferences for gnome-terminal and gnome-editor from the command line. To do this I need to know the various relevant key-value pairs and gconf-editor used to display them for all Gnome-based apps. Unfortunately, in 18.04 desktop gconf.editor only shows values for gconf-editor itself and not for any other Gnome applications.
Given this, what is the best way to change Gnome app preferences from the command line in 18.04?
