    My RPi runs fine with a 5″ HDMI Touchscreen from Waveshare, but calibration of the touchscreen is not possible.
    Means, that I can control only the center area of the screen, but not the Buttons at the bottom nor the two buttons at the top of the screen, I cant reach them. Control by Mouse or Keyboard works fins.

    I tried several things, but till now without success.
    – installed the tslib and used the integrated ts_calibration function. That seems to go and some new values are written in /etc/pointercal but nevertheless, same touchcontrol issues
    – tried to find some UserInterface in the Windowmanager, but there is no option to calibrate a touchscreen
    – I searched the web now for hours, but can only find configurations and examples that do not work for me (to be honest, cant exactly remember, which things I tried in detail, have been too many)

    Do I have to calibrate under the CLI or the windowmanager ?

    In my opinion, the waveshare displays arent the best at all, but for this job almost well. Seems, that nobody else had to calibrate his touchscreen at all, or am I wrong ? Do these displays work right out of the box ?

    Hope somebody points me into the right direction and I can get my touchscreen to work, because its the last step to a working Max2Play Controller for mounting on the wall…

    Hello martin-s and Bull,

    Thanks for your request.

    Maybe this is a help for you:

    It is possible that the calibration file is not automatically loaded from the path which you have used. Usually the config should be saved under /etc/X11/xorg.conf.d/ or /usr/share/X11/xorg.conf.d/

    For example: /etc/X11/xorg.conf.d/99-calibration.conf

    Please send us what stands in your config file, so we can try this.

    Best Regards

    Hello Christoph, many thanks for your reply.

    I’m little afraid because the last time that I tried to install the drivers from waveshare the max2play didn’t start. It prompt for a user & password in console but any user/password that I’ve been tried didn’t works, and finally I reinstalled again the max2play writing the sd again.

    So please What do you need exactly that I need to do to send you the files that you need.

    the installation of the drivers with user pi or root(given a password)
    the installation of the calibration software?
    or whatever.

    I don’t have any problem to collaborate and do all the neccesary tests that you need, but I need to know what do you need that I need to do in raspbian because I’m quite new using this system.

    thank youn in advance
