NextWindow Touch Screen Working on Linux

This page explains how to get a NextWindow touch screen working under Linux on the X Windows system. This has so far been tested on the Knoppix (based on Debian) distribution.

The following information has been provided by a Nextwindow client in September 2006. An alternative (previous) solution is given here.

Requirements

Linux 2.6 kernel series

evdev module compiled in the kernel or loaded as a module

Evtouch Touchscreen Driver installed

Example XF86Config-4 excerpt

Calibration

Don't forget that once you have the USB communications working, the touch screen requires a simple calibration procedure.
