Ha-ha, that was fun. Either you have done that on purpose, or you're testing that on a server back from 2005. :-) You can check `xdpyinfo -ext RENDER` too, it's supported since about 2003.
Xrandr is just a tool to request that information. Xdpyinfo is another one. X-server knows about subpixels and uses them for a loooong time.

Why do you think it won't work? Hah! Try Wayland with legacy NVidia driver (hint: it doesn't work)!
> See "enum transform" and various related events and requests
Have you seen that yourself? It's just display rotation, similar to xrandr, not the surface rotation done by compositor.

"Screen 0 (sub-pixel order Unknown)"
i915 driver FWIW.

Can you provide a reference to X specification about subpixel order and its relationship with display transformation? And not for xrandr, please.

That's an extension, not the X protocol itself.

Yes, that's true. It also doesn't matter at all.

In X world extensions are part of the X11 protocol. For example this particular extension is part of X11R6.9, you can see that in its URL.

But it's not a part of my X server.
Waaahhhh! X encourages fragmentation!
