January 4, 20233 yr I am going to have to type a lot of words which I have no idea what they mean.... but here goes. I have bought an Orange Pi 4 LTS and the official touchscreen which goes with it. This connects via a flat ribbon cable into what is called port LCD1. I believe it is MIPI - although have no idea what that means. The screen works perfectly, but is in portrait. I can rotate the screen to landscape with randr or in the gui, but the touch doesn't rotate with it. I tried using xinput (which wasn't installed) and xinput calibrate as well, but neither did anything. I believe that the screen was installed by adding a line in a file called orangepiEnv.txt (to something like overlays=afj101), which I believe is used by boot.conf. How do I rotate the touch part of the screen? I have no idea what I am doing.... Thank you!
