View source for Touchscreen Calibration (DIVELK)

=== Weston ===
If the Weston compositor is running in the background, it is necessary to remove the old udev rules, and restart the device in order to calibrate the touchscreen.
<pre>
 rm -f /etc/udev/rules.d/ws-calibrate.rules
 reboot
</pre>
At the next restart the weston-calibrator tool should automatically show up. Tap on the red cross appearing on the screen to calibrate the touch panel.

'''Note:''' In the case of root filesystem over NFS and SD card plugged in, make sure delete also the calibration rules stored in the SD card partition before rebooting:

<pre>
 rm /etc/udev/rules.d/ws-calibrate.rules
 rm /run/media/mmcblk0p1/ws-calibrate.rules
 reboot
</pre>
