Calibration of Touchscreen under Raspbian

A great Link collection for touch calibration tools: http://tias.ulyssis.org/calibration/ and a great overview of the whole USB-HID and USB-non-hid touch issue:http://tias.ulyssis.org/calibration/device_support.html

A new generic calibrator

Since I originally created this overview, I have started the xinput_calibrator project, hosted on freedesktop.org. Xinput_calibrator is an easy to use generic touchscreen calibration program that can calibrate all Xorg drivers (except tslib).

To understand how touchscreens are handled nowadays, check out this other page that tries to explain it all.

Name Application Config Notes Requires
tslib ts_calibrate dynamic Appearently the standard for touchscreens on embedded ARM systems (according to this post). Originally developed for Kdrive, but there is a port for Xorg called xf86-input-tslib(packaged in ubuntu and gentoo among others). a /dev/input/eventX device and a /dev/fbY video framebuffer device
