The exynos 5422 has no rotating scanout hardware. Xrandr usually only exposes the interface to change scanout hardware orientation. There have been patches for the drm to change the drm engine to be able to chain the hardware scaler/rotators to the drm, which would be able to do roughly the same, but for now those has been rejected. There is one Xorg driver implementation that actually does it in software, that's the intel driver, since the smallest intel SoC's have no changeable scanout hardware.

So if you want to rotate, you end up with making your software rotate (chromium is plain html at no rendering costs), or use compton-gl compositor and let the compositor rotate (costs gles and memory bandwidth), use Samsung's patches, or try to fix the Xorg driver...

I mean: if the intel can do it, armsoc should be able to do it too.

On Ubuntu you can rotate the screen with xrandr command.

Example

xrandr -o left

xrandr -o right

xrandr -o inverted

xrandr -o normal
