Just a quick note for anybody who’s struggling with Touchscreens on the RaspberryPi.
I just downloaded the latest Raspbian Image 2013-02-09-wheezy-raspbian.zip and started it. My Faytech 7” Touchscreen just works out of the box and it even works with JavaFX applications. No more kernel compilation!
One tiny thing you might want to do is to calibrate the touch controller. xinput_calibrator will do the job but you have to compile it yourself.
sudo apt-get install libx11-dev libxext-dev libxi-dev x11proto-input-dev wget http://github.com/downloads/tias/xinput_calibrator/xinput_calibrator-0.7.5.tar.gz ./configure make sudo make install xinput_calibrator
Touch the points until the application closes. Follow the instructions on the console output and create the configuration for X11. The directory for the configuration file is /usr/share/X11/xorg.conf.d instead of the directory shown by xinput_callibrator.
Reboot and you’re done!
