HI @arj_don ,

You can use weston-touch-calibrator, also note you may need to pass touch device you want to calibrate.

Weston-touch-calibrator problem: no devices listed

Hello, I added a touchscreen to the verdin development board’s usb port, gave the command evtest and the driver was found, as shown below: /dev/input/event3: EloTouchSystems,Inc Elo TouchSystems 2216 AccuTouch® USB I configured the weston.ini and added it to the file: save-calibration.sh in /usr/bin, as per the link: When I give the command weston-touch-calibrator, I get as a response that no touch device was listed. What would be the problem?

Best Regards
