Users can adapt or customize the desktop environment to their preference by simply editing three files. However, for easy configuration, users can use other programs that offer graphical user interfaces to configure settings and menus. In addition, Openbox is the standard window manager of LXDE or LXQt desktop environments and therefore also of Lubuntu. Whereas there are various unofficial variants of Ubuntu which also rely on Openbox.
