What's currently lacking is that xf86-input-evdev doesn't generate click events (something like a LEFT CLICK) for touches. What also supports Linux MT events is Android Éclair http://lukehutch.wordpress.com/2010/01/06/my-multi-touch-code-ported-to-eclair/ It Uses: ABS_MT_POSITION_X ABS_MT_POSITION_Y ABS_MT_TOUCH_MAJOR ABS_MT_WIDTH_MAJOR Without ABS_MT_TRACKING_ID.
