Touchscreen inverted Y

Hi, I am giving a test to Emteria, it's fine, i Like it. However my external USB touch screen appears do be inverted on the Y axis.
Changing the value in sys/module/usbtouchscreen/parameters/swap_xy is no point because it swaps both axes.
In Raspberry OS I've solved the problem editing the device's transformation matrix but here I cannot find anything similar to play with.
Any clues for me?


  • Hi @paul_h
    Depends on the setup, but should be achievable. What emteria version, what RPi model and what display are you using?
