void is an dummy/null Xorg input driver. It doesn't connect to any physical device, and it never delivers any events. It functions as both a pointer and keyboard device, and may be used as X server's core pointer and/or core keyboard. It's purpose is to allow X servers pre version 1.4 to operate without a core pointer and/or core keyboard.

Please refer to xorg.conf(5) for general configuration details and for options that can be used with all input drivers. This driver doesn't have any configuration options in addition to those.
