gdk-disable-multidevice ()

Disables multidevice support in GDK. This call must happen prior to the gdk-display-open, gtk_init(), gtk_init_with_args() or gtk_init_check() functions in order to take effect.

Most common GTK applications will not ever need to call this. Only applications that do mixed GDK/Xlib calls could want to disable multidevice support if such Xlib code deals with input devices in any way and does not observe the presence of XInput 2.
