Touchscreen is more precise after a calibration, but this action is not mandatory.
Calibration data are erased after each firmware download into STMicroelectronics boards.
The steps described below have to be performed on a running board :
- Edit and change the value of the touchscreen_calibrator to true in the libinput section of the weston.ini Weston configuration file[1]. #[libinput shall be uncommented.
vi /etc/xdg/weston/weston.ini [...] [libinput] touchscreen_calibrator=true calibration_helper=/bin/echo [...]
- Restart weston
systemctl restart weston@root.service
- List all the touchscreen devices
weston-touch-calibrator
could not load cursor 'dnd-move'
could not load cursor 'dnd-copy'
could not load cursor 'dnd-none'
device "/sys/devices/platform/soc/40012000.i2c/i2c-0/0-002a/input/input1/event1" - head "DSI-1"
- Launch calibration with the input of the touch panel
weston-touch-calibrator /sys/devices/platform/soc/40012000.i2c/i2c-0/0-002a/input/input1/event1
If the calibration succeeds, no message will be displayed on the console. If it fails, the following message will appear:
weston-touch-calibrator error: Calibration verification failed, too large error.
Touchscreen identifier may vary, depending on the devices that are connected to the board. Recommendation is to unplug all the additional input devices before booting. Otherwise, it is up to You to adapt the command line.
