Thank you @Wheaten:
@Wheaten: It is not a setting in “99-calibration.conf”, but in “/usr/share/X11/xorg.conf.d/99-fbturbo.conf”.
@Alex18 If the file “/usr/share/X11/xorg.conf.d/99-fbturbo.conf” is empty, it does not exist yet.
You can download and copy it to “/usr/share/X11/xorg.conf.d”:
wget https://raw.githubusercontent.com/waveshare/LCD-show/master/usr/share/X11/xorg.conf.d/99-fbturbo.conf
sudo cp 99-fbturbo.conf /usr/share/X11/xorg.conf.d/99-fbturbo.conf
Then edit the file as described. (The downloaded file aready has “fb1”).
