Calibrating touch in Linux

One of the primary problem seen when integrating touch controller in Linux is calibration. I would like to introduce two different methods of calibration. Please use the table below to choose the correct tools

Tool name Application name Requirements Remarks
tslib ts_calibrate The touch device need to be exposed as /dev/input/eventX input device and a video framebuffer support like /dev/fbY is mandatory Standard for touchscreens on embedded ARM systems
xinput_calibrator xinput_calibrator Needs no special driver Used on X based devices with no frame buffer support
