I use following screen: http://www.chalk-elec.com/?page_id=1280#!/~/product/category=3094846&id=7703686
(10" LCD LVDS bundle with touchscreen)

It should be supported: http://jdk7.java.net/fxarmpreview/javafx-arm-developer-preview.html

Touch events work with gnome but not with JavaFX apps.

Maybe this ticket is similar to RT-26186?

Lens log is attached.

I tried to use the screen without keyboard, without keyboard and without mouse, with an external powered USB hub - touch did never work.
