ok did it again and still not showing UI on screen
Check all quotation marks in “/etc/X11/xorg.conf.d/99-calibration.conf”. I suggest to substitute them by manually retyping them. I guess copying the text from the forum changed the quotation marks in some way.
yes you were correct the quotation marks were replaced with these > >.
manually retyped and the UI is back up and running!
Bad news the damn calibration didn’t work, it’s still the same.

current calibration values: min_x=0, max_x=65535 and min_y=0, max_y=65535
If these values are estimated wrong, either supply it manually with the --precalib option, or run the ‘get_precalib.sh’ script to automatically get it (through HAL).

Maybe it could be an option to use a calibration file from the manufacturer of the display. This wouldn’t be ultra precise, but probably better than what you have now, Could you provide the name of the manufacturer and the exacr model name of the display?
