As I recall (having worked on a touch screen system a few years ago), your X
driver probably needs to be configured to know about your event driver (your
touch screen driver), and then when X "boots", everything's all set. The touch
screen is treated like a mouse click.

Now... Getting X to tell you that the mouse was clicked means that you need to
run your application as part of starting X. There are numerous ways to do that,
depending upon which window manager you're using.

Does that help?
