Maybe this one helps

New feature: X-Y touch-controller

@jofemodo Amazing! I just have finished building my own zynthian, fully by myself. I’m testing this feature with my 2.8 PiTFT Capacitive. Caused by “rotation=90” in webconfig, when I move in X-axis, the cross move in Y-axis, and vice versa. If I change rotation to 180, the movement works properly, but the screen obviously is seing bad. Any trick to resolve this? Thanks in advance, this project is gorgeous!!!

Hi my config is:

Web display config:
dtoverlay=piscreen,speed=16000000,rotate=270

SSH:
root@zynthian:~# cat /etc/X11/xorg.conf.d/99-calibration.conf
Section "InputClass"
Identifier "calibration"
MatchProduct "ADS7846 Touchscreen"
Option “Calibration” "239 3919 3902 193"
Option “SwapAxes” "0"
EndSection

and good think to do is

root@zynthian:~# apt-get install -y xinput-calibrator
root@zynthian:~# DISPLAY=:0 xinput_calibrator

yep, this is helpful as well

Integrating custom config files for other Displays (It was "Touchscreen waveshare")

The calibration of @norbim doesn’t work for rotated screens. My numbers are 205 3754 3801 226 You can do your own calibration: apt-get install -y xinput-calibrator Create a file calibrate.sh on the zynthian that contains #!/bin/sh xinput_calibrator -v make it executable chmod +x calibrate.sh stop zynthian and run calibrate systemctl stop zynthian startx ./calibrate.sh Follow the screen instructions In the ssh output where you started startx, you find the calibration values
