Thank you for the useful information but there is a question. I need to keep power cable on top. So that, I have 180 rotation comparing to yours but I can't adapt the touchscreen rotation. Either it is inverted or swapped. No way to match so far. Do you have anything in your mind to figure out this issue?

You can get, after the calibration of the screen, some informations when you opened with the terminal how to make the calibration permanent
