Phoronix: Wayland 1.0 Stable Release Is Imminent
Kristian Høgsberg spoke this week at XDC2012 about Wayland and Weston. Here's a short recap plus some videos that include new demos of this promising project...

Funny how krh is using weston for presentations and they haven't implemented a screen clone feature. :eek::eek:
;);)
On a serious note how much more development will wayland need after 1.0. :confused:
I'm honestly curious as to what this is going to bring to the Linux desktop. All I know is that it's supposed to be somehow better than X11. Can anybody define the "better" part for me and tell me why I should want to use it?
If Weston compositor offers tear free desktop and low performance hit, it's a win...
Xorg in 25 years haven't acomplished this :)
You -as an end user- will get pretty much the same experience you are getting with X11. Wayland cuts what is not needed in order to have a graphic stack since all the functionality that was in X11 moved to other places.Quote:

As an end user? Not a whole lot. X is being replaced for a lot of reasons but some of the big ones are: Break the forced backwards compatibility. X used to do a lot of things, many of those things (font rendering, memory management, and a few hundred other things) have since been moved to other, smaller, programs or into the kernel. BUT, some programs still depend on X being able to do those things so they have to stay in the server. Thats why you hear people talking about X12-- its an oppurtunity for the developers to just go "F*ck backwards compatibility" and break as much stuff as they want to modernize the X server.Quote:

Wayland is meant to do something X was never meant to do--- get out of the way. Let the kernel, let the toolkits, let the drivers do their thing and dont have the big bad bouncer that is X in the middle of things saying "No you cant do that because 20 years ago we hadnt thought of that"
A nice little side affect of this will be more portable toolkits. GTK and QT and KDElibs and EFL will have to support X and Wayland at the same time because some users will be on X, some on Wayland, that means the libraries cant care about what protocol they are speaking--it has to be abstracted away. This way, if 10 years from now we decide that Wayland was great for 2012 but not so great for 2022, hopefully moving to a new backend will be easier because the toolkits ALREADY have to be fairly backend agnostic.
It is supposed to simplify things.Quote:

What Wayland is trying to do is to make a minimal display server which only offers what is needed, and interacts nicely with all these new technologies. Of course, X11 also interacts nicely with them now, but it is very large and complicated, difficult to maintain, and most of its functionality is not used on a modern desktop anymore. So the idea is to make the regular desktop run on top of kernel+mesa drivers and FreeDesktop.Org technologies, and use as light a display server as possible, while all the network transparency stuff X traditionally does is moved to an optional codepath which is only run when needed.
It sounds quite nice in theory. The problem is that the reporting here is sensationalist, and a religious cult of Wayland has formed here on Phoronix, expecting the Kingdom of God as soon as Wayland descends from heaven, and are expecting stupid things (ridiculous speedups, better user experience). Wayland is an interesting technology, currently developed as a hobby by one guy aided by some occasional contributors, but it seems to have a lot of goodwill with many important developers in the Free Desktop ecosystem, so it is possible that in a few years, some people might replace X with it for some purposes.
At that point, we'll have to see whether it's time to retire X, or what will happen. So far, X has adapted and triumphantly defeated every challenger, but it's showing signs of age. In the end, it will affect developers more than users.
You are severely mistaken: Wayland is and has been for a long time developed by Intel and Collabora among other companies commercially.Kristian Høgsberg works on Wayland for Intel for example.Quote:
