evdevtouch does not work for single-touch devices when mtdev is enabled

    XMLWordPrintable

Details

    Description

      Currently, when mtdev is enabled during compilation, QEvdevTouchScreenHandler will always set m_singleTouch to false. This however means that the hw_range_ values are read incorrectly (using ABS_MT_POSITION* instead of ABS_*) and the ABS_[XY] events are ignored, which breaks single-touch support.

      The fact that the hw_range__ values are all 0 causes the position to be set to NaN which triggers <https://bugreports.qt.io/browse/QTBUG-86207>.
