Recalibrating the Touchscreen

You can recalibrate your target's touchscreen at any time

To recalibrate the touchscreen:
  1. Remove the file /var/etc/system/config/calib.localhost.
  2. Run reboot. The system reboots and the calibration utility runs, allowing you to recalibrate the touchscreen by touching the center of a target pattern multiple times and then accepting the new calibration settings.
