Thanks for sharing your findings !

You can mark it as solved :) Use the "Topic Tool" button and change the type of the thread to a question, then you'll be able to mark it as solved :)

Adding one more variable did the trick.

QT_QPA_EGLFS_DISABLE_INPUT=1

Thank you for your help. It now works totally fine. Topic can be set as Solved

When i insert a USB mouse into the raspberry the mouse works directly and every mouseclick is triggered

Well, I tought it works completely but there is one problem. When I push on the MouseArea the cursor is going to that position where I push but most of the time there is not a onclicked event triggered. When I push multiple times on the mousearea sometime the onclick event will be triggered, maybe 1 out of 10 á 15 times.

I have connected the touchscreen to a Windows machine en every push on the screen is triggered. This is why I thing that there is something wrong with my tslib configuration.

Can you help me with this problem?

ts_open() failed (No such file or directory)

But when I do ts_calibrate of ts_test on my raspberry everything works. Can someone help me with this?

I've founded that i allready installed tslib via apt-get. I think the git install was conflicting with the already installed tslib. No I removed the tslib via apt-get and install from this git directory. Now ts_calibrate works. I have calibrated the screen. Also ts_test returns values.

But when I run my program (see below) from QT creator and hit the blue rectangle nothing happens. The program had to close. When i put the rectangle in the left upper corner and run the program and touch the screen the rectangle get hit and the program close. So the touch works only the movement of the mouse cursor doesn't go to the point where the touch is. The mouse arrow stays in the left upper corner. Can you tell me what I'm forgetting?

My QML code

import QtQuick 2.3
import QtQuick.Window 2.2

Window {
    visible: true

    Rectangle {
        x:100;y:100;width:100;height:100
        color: "blue"

    MouseArea {
        anchors.fill: parent
        onClicked: {
            Qt.quit();
        }
    }
    }
    Text {
        text: qsTr("Hello World")
        anchors.centerIn: parent
    }
}

ts_open: No such file or directory

Could you help me again with this problem?

Sorry for my noob question but: How can i do that?

Can you help me further?

The Embedded Linux chapter has pointer to help you find out what may be going wrong

How are you starting your application ?
