I’ve search and i found that my screen is the 2423 :
| Ada# | Name | Size | Pixels | Touchscreen | Backlight | Header |
| 2423 | PiTFT Plus | 2.8" | 320x240 | Capacitive | variable | 40-pin |
I Think this is that setting for my screen :
Section "InputClass"
Identifier "captouch"
MatchProduct "ft6x06_ts"
Option “SwapAxes” "1"
Option “InvertY” "1"
Option “Calibration” "0 320 0 240"
EndSection
And that module
sudo nano /etc/modules
and add ft6x06_ts on a line at the end
I will try after a fresh install !
