But if calibration doesn't work, maybe you have a problem with the touch screen or better with the qt driver you use. I had some problems to use my touch screen too, calibration doesn't seem to work, cursor move in a very strange way with an error in position not linear and not really predictive. I realized I was using the default driver for pointing device which simply not work with my device.

I have to follow those steps to make it works :
  1. configure Qt with -qt-mouse-linuxinput option and rebuild
  2. find the device corresponding to my touch screen : on my board it was /dev/input/event1.
  3. export QWS_MOUSE_PROTO=LinuxInput:/dev/input/event1 on my board before running the QWSServer.


After that my touch screen works fine.
Hope it can solve your problem too.

Hi nix,

Thanks first of all for suggesting me.

I have sort out the problem, now my touch screen working properly.
Actually it's was calibration problem, i was not calibrating in proper way.
I have done google-search got idea for calibration.

Thanks & Regards,
