Input handling in wscons and X.Org

Matthieu Herrb

Abstract

This talk will present the different layers that handle input, from the key that gets pressed or the mouse motion to the applications, all the way through the kernel drivers, X drivers and libraries, in the case of the OpenBSD/NetBSD wscons driver and the current and future X.Org server. It will cover stuff like keyboard mappings, touch-screen calibration, multi-pointer X or input coordinates transformations. It will show some problems of current implementations and try to show how current evolutions can solve them.
