==== X11 ====
For touchscreen calibration under the <code>X11</code> framework, the touchscreen should be calibrated using the <code>xinput_calibrator</code> utility:
<pre class="workstation-terminal">
root@sdv03-lite:~# export DISPLAY=:0
root@sdv03-lite:~# xinput_calibrator
Setting calibration data: 0, 799, 0, 479
Calibrating EVDEV driver for "TSC2007 Touchscreen" id=6
current calibration values (from XInput): min_x=0, max_x=799 and min_y=0, max_y=479
Doing dynamic recalibration:
Setting calibration data: 31, 763, 19, 474
--> Making the calibration permanent <--
copy the snippet below into '/etc/X11/xorg.conf.d/99-calibration.conf'

MatchProduct "TSC2007 Touchscreen"
Option "Calibration" "31 763 19 474"

then copy the calibration data into the configuration file:
