<div>I tried putting the calibration stuff in /etc/X11/xorg.conf.d/99-screen-calibration.conf</div>
<div>( I also tried /usr/share/X11... etc once the machine starts you can get the properties</div>
<div>and see the calibration is what was set by the conf file. The when you do the map-to-output</div>
<div>put it back to some other values. </div>
