Wayland is a critical technology for Linux desktop community. X11 has been a reliable workhorse, but its time is up - simply too much cruft accumulated over the years that's not even used anymore. Yet all of it needs to be continually supported, adding to complexity. No one uses X11 primitives for drawing apart from bitmap functionality - even repainting dirty regions (expose events) often involves sending over a new…

I was sold on Wayland in terms of technology a while ago. Where Wayland is losing people is when is it going to be ready to use? Sure, you can install Wayland now, but there are no applications that target it. Yes, XWayland is meant to solve this problem. But, XWayland is not ready yet (or is it?) and Wayland is still "just around the corner." That may be for legitimate reasons, but it's what the article really shoul…

Raspberry Pi seem to be aiming to switch in the coming months:

Seems pretty cool! What kind of latency it achieves?

Can anyone clarify please, how is full OpenGL stack supported in Wayland cases? In X there is libglx, while Wayland relies on OpenGL ES. So how for example would some games which need full OpenGL work on Wayland?

krh is working on a lossless "codec" that uses a rsync-like rolling hash that should provide good compression with no artifacts (as long as the app isn't too skeuy). http://people.freedesktop.org/~krh/rolling-hash/

Isn't that what Airplay Mirror (and the underlying Intel tech doing the encoding on the hardware) does? To the Apple TV, this is merely MPEG4 over HTTP Live Streaming

Some more facts about Wayland and client-side window decorations, quoted from here: http://blog.martin-graesslin.com/blog/2013/02/client-side-wi... - Nothing in Wayland requires them - QtWayland allows Clients to turn them off - KWin as a Wayland compositor will use server side decorations

> "No aliasing when rotating/wobbling windows" Has anyone ever used those things for more than a single day? I honestly thought the current compositing window managers don't even support that novelty stuff anymore.

Daniel Stone actually did a talk involving much of the same subject matter called "The Real Story behind Wayland and X". I'd recommend that over this article (which was partially written by the same guy). He's actually a really charismatic speaker. https://www.youtube.com/watch?v=RIctzAQOe44

Thanks that was rather informative.

He is quite a dramatic speaker. I'm surprised because 99% of the technical talks you hear have a speaker mumbling away about minutiae hoping enough of the crowd will fall asleep that they can slip out unnoticed.

Why is it impossible to evolve X11 to a satisfactory state?

In retrospect, Xorg developers like Daniel Stone actually implemented most of the hacks in that list and have come to regret it.
