QML & touch screen => evdevtouch: Could not read from input device (No such device)



  • Hi,

    I have a QML application which uses a touch screen as input Normally everything works fine.
    But after restarting the touch screen, I get the following error message:

    evdevtouch: Could not read from input device (No such device)
    

    When receiving this message, touch screen events are not longer recognized. The application itself is running, because I see the time is inkrementing in the application.
    After restarting the application the touch screen is working fine again. I don't have to restart the whole system.

    Does anyone have an idea what could be reason for this error message and how I could resolve it?

    Kind regards,
    MHermann
