http://askubuntu.com – I have tried several options from various forums. Proper calibration should not be this difficult. I have run the calibration tool and most sites say to include a section of the output in a particular file in the /etc/x11/.... file. This file does not exist. One site said the file was in the /usr/x11/.... directory and that an additional option for calibration should be added. This made no difference. I included the section from the calibration tool in this file renaming the input device. This also had no effect. Does anyone know how to successfully calibrate my touchscreen, and can Ubun (HowTos)
