Hello,

I am using OPI one with Armbian_5.90_Ubuntu_bionic_4.19.57, so I fliped my 7" touch screen display vertically (rotated 180) by modifing:

/etc/X11/xorg.conf/01-armbian-defaults.conf

and it worked, but the touch doesn't correspond with it (still points as it was before rotation).

 

how can i flip the touch information (x,y) coordinates vertically (rotate by 180)?

 

Regards,
