Hello! No not at all! The window manager is just a "helper". Infact the W-window system was written as a "policyfree" environment. It was a design idea *not to have* the application dependent on the window - mangager". So this is *not* a strange thing at all. *NO*! functionality is dependent on the window mangager! Some programing toolkit are a little bit crippeled to handle itself in respect with resize, fonts and sutch. Gtk have some issues without window mangager - but not mutch. If you write a X-window application without a toolkit you have compleet control. (This is *verry* akward though). So if you want to write a kiosk there is *no need* to have a window manger. /gh Den 2016-03-18 kl. 06:00, skrev Jasper St. Pierre: > I highly recommend against this.
