Primary display orientation not correct on Tab S7 Plus

[himekifee]

I'm porting ubuntu touch to Samsung Galaxy Tab S7 Plus through ubports gsi. It went to the stage of displaying but the touch input is shifted. From what I remember, the situation is the width is recognised as height and vice versa. When I do LineageOS porting, there is a property ro.surface_flinger.primary_display_orientation=ORIENTATION_270 which swapped width and height, also xDpi and yDpi to solve the issue. I don't think I can find an option here so I want to ask if we can bypass this.

Nvm, the solution seems to be udev rules to apply a transformation matrix.
