Hello,

I'm trying to make working qml qt5 application (qt5.10) compiled for intel nuc (x86). App can un just fine but I have an issue with touchscreen. Touchscreen is detected and report events like:

So looks like /dev/input/event5 is touch screen but when run qml application (with export QT_LOGGING_RULES=qt.qpa.*=true) and get this:

in my qt app I'm using qvirtualkeyboard which will popup when want to edit something but as touchscreen not working I cannot enter anything. Any ideas how to solve this issue? Thanks.
