First off, thanks for posting this. I had no idea libhybris even existed until I happened upon this thread. Second off, libhybris doesn’t allow you to use an android kernel without dalvik, per se, in fact you could already do that easily with some source modification. Hybris is much better! It allows us to use a stock, armhf Linux kernel and load Android proprietary driver blobs as usuable Linux kernel modules. What this basically means, is that any desktop Linux can now be ported to Android devices and still keep the ability to use the touchscreen, call the GPU, use bluetooth, etc. It exposes the GPU with the OpenGL ES API instead of OpenGL, so the experience would still require porting of most software that uses the GPU(games in particular).
Wayland can already be used on, and has been tested with, libhybris. And QtCompositor is a great way to design Qt-based Wayland compositors. All the pieces are in place, we just need someone besides Canonical to do something about it.
I’m working on a port of Debian, currently, but bootstrapping the OS so far has proven to be a pain. I may try Arch Linux or Gentoo instead. Also I have no experience creating compositors, but it’s probably going to come down to me trying. I’ll follow up if I find/create anything useful.
