Qt4 x11 taget image for colibri_imx6 module comes with a qt4-x11-demo-init script, which calls a calibration script file (“xinput_calibrator_once.sh”) to run touch screen calibration application before the qt demo application is executed. But we have never seen a screen fired up for us to do calibration before the qt demo runs. We did make sure the calibration data file (“/etc/pointercal.xinput”) does not exist so that calibration is always required every time Linux starts up.
However if executing the calibration script manually at command line, we do see a calibration screen and the calibration is working just fine.
Hi
Starting the calibration likely never worked in that script, sorry.
Also the script uses a very minimalistic way of starting X11.
Probably moving the calibration after the start of the qt application in the following way solves your use case:

If that is to simplistic one probably would have to add xinit to the image and rework the startup of X11, calibration and the qt application into ‘startx’, /etc/X11/xinit/xinitrc.
