I want to display the icon trio of "Min/Max/Close" on both sides of the title bar. Years ago I was able to do so with the following command:

gsettings set org.gnome.desktop.wm.preferences button-layout "minimize,maximize,close:minimize,maximize,clo se"

It does not work for me now. I would appreciated if the needed command could be supplied, perhaps even using dconf-editor (I could not understand how to use the GUI) if that's what it takes.
