calibrate touch screen (Raspberry PI 2 b+)

Question

I have the 7 Inch TFT Touch Screen LCD Monitor For Raspberry Pi + Driver Board HDMI VGA 2AV calibrated, but every time after the restart I have to calibrate it new.
Is there a way that he remembers it.
(Sorry for my bad english)

Answer 1

You need to store calibration data in /usr/share/X11/xorg.conf.d/99-calibration.conf which you got from xinput_calibrator.

Here, follow these steps.

1. Use xinput_calibrator utility.
2. copy the output, calibrator gave after calibration.
3. sudo nano /usr/share/X11/xorg.conf.d/99-calibration.conf
4. Paste the data
5. ctrl + x, yes to save.
6. sudo reboot to make it effective.

It should be done by now. :)

Hope it helps.
