I noticed that on the Orangepi image, touch screen response is good but on Armbian, unless you keep the display on portrait mode, the touch response is off by whatever rotation you have set, so if youre landscape, moving your finger up will move the pointer left, etc.
I did some digging and OPI Ubuntu uses wayland while Armbian uses Xorg X11. Looks like I need to figure out the tweeks for the touchscreen orientation in Xinput.
