I need to calibrate the touch of the pi on a official 7' display, in vertical position. I use the screen utility to rotate, and I see DSI-1 & HDMI-1.
then is use this string :
With the Pi3 (display_rotate=3 ) works, and the touch is perfect.
Code: Select all
#!/bin/bash DISPLAY=:0.0 xinput --set-prop 'FT5406 memory based' 'Coordinate Transformation Matrix' 0 -1 1 1 0 0 0 0 1
with pi4, it works only on half screen because on the top I see the second desktop (hdmi-1) so I can't calibrate.
is there a way for solve this problem?
