hi Rich, thanks for finding this out!

Code: [Select]
Option "Calibration" "min-x max-x min-y max-y"

That makes the default config I have wrong, as the middle 2 numbers are smaller ones indicating they are minimum coordinate values. I will try flipping them but I wonder how does it even function correctly in Raspbian  ???

Maybe they used:
Code: [Select]
Option "InvertX" "1"The link I provided doesn't give any details on how the inversion is implemented.

Hi Rich

Did you manage to get the seven working? Can you share the working solution?
