Comment 1 for bug 1748213

Has no one found a better solution for this in the last 2 years? The official documentation makes no reference to if these other values are reasonable or not: https://www.raspberrypi.org/documentation/configuration/config-txt/video.md (under lcd_rotate)

> This flips the display using the LCD's inbuilt flip functionality, which is a cheaper operation that using the GPU-based rotate operation.
>
> For example, lcd_rotate=2 will compensate for an upside down display.

Is the only real solution to use X to remap the touch screen inputs?
