ROTATE_DISPLAY does not behave as expected

[damianpowell]

I am trying to create a kiosk in portrait orientation. I have set an environment variable ROTATE_DISPLAY=left but this appears to rotate the chromium window and relocate it's top-left corner to the new position but it does not appear to resize the window to 1080x1920, as expected. I have tried specifying the window size manually, via WINDOW_SIZE=1080,1920 but that appears to just change the black area of the screen to white, but not render content there.

Furthermore, the touch-panel doesn't appear to rotate with the screen, although I think I have a solution for this by including xserver-xorg-input-libinput and modifying 40-libinput.conf.

I am using a Raspberry Pi 4 (4GB).

I would be extremely thankful for any assistance on this - I've been hitting my head on a wall for nearly a week now!

I am running into a similar problem. While the (hdmi) display rotates, touch input is still rotated by 90°. Strange thing is that an external mouse behaves as expected. Any Ideas on how to rotate the touch input as well? Thank you!
