Is there an ETA for Linux Wayland support?

[Thiago Milczarek Sayão]

I don’t officially speak on this matter, nor will I attempt to answer your
question directly, as I’m unaware of any internal company efforts in this
area. However, it would be beneficial to have a centralized resource to
track ongoing efforts, ensuring we avoid duplicating work that might
otherwise go to waste.

That said, I’ve observed some progress in improving XWayland (*), and I’ve
personally tested it and submitted bug fixes. Efforts have also been made
to enable Robot to work with XWayland using PipeWire, which is a great step
forward.

(*) XWayland is the compatibility layer that allows X11 applications to run
on Wayland.

Creating a simple state-based display using the pure Wayland protocol is
relatively straightforward (specially with Java 22 and FFM). However,
implementing all the necessary details for a fully functional and
feature-complete Wayland backend is a substantial endeavor. One challenge,
for instance, is that Wayland’s design choices intentionally avoid certain
features (like not having a global cursor position and not allowing window
management operations).

I submitted a pull request to enable EGL on Prism ES2 with Wayland in mind.
This enhancement allows for GL rendering using EGL, which is a critical
requirement for a Wayland compositor.

I also conducted some experiments and managed to display a window using
only the Wayland protocol (*) in Java, leveraging jextract and the Foreign
Function & Memory (FFM) API. However, this is far from achieving a fully
functional Wayland Glass backend.

(*) Wayland is just a specification, many compositors implement it.
