Touchscreen input is a very platform specific consideration.  Storyboard works with a number of 
            standard input devices and abstracts the implementation specific behaviours for press, 
            release, motion and multi-touch system events into standard
            Storyboard events.  These input events are described in the Storyboard
            standard event definitions section of this document.
The configuration details for setting up and troubleshooting two popular Linux input systems are described in this document. For other system or touchscreen specific configurations consult the operating system or touchscreen vendors documentation.
