Gnome Tweak Tool
Faced such problem, installed The gnome Tweak Tool utility through the terminal
sudo -i *password*
sudo apt install gnome-tweak-tool
everything is set, all the hood, opened the program via ' sudo gnome-tweak-tool
And then the problem itself began, that I would not change in this program, I do not change anything,what could be the problem, maybe you need to somehow apply these changes, but how? Maybe you need to put priority to this program through the terminal, I should just Xfce, in fact he's got his editor.
Then everything changed,simply by selecting from a list, but in gnome tweak tool. Whatever I change, nothing applies.
If it helps, I have a Xubuntu distribution.
