Besides tool-kit advancements, other happenings in the world of Wayland this week pertain to coming up with a suitable window stacking and raising design for this next-generation display server.
The Enlightenment project has made significant progress in making their key libraries compatible with the Wayland Display Server.
There's some RFC patches out this week from Intel's Jesse Barnes that provides sprite support for the recently announced Weston Compositor for the Wayland Display Server.
Kristian Høgsberg of Wayland fame has announced Weston for Wayland...
As a slightly belated Christmas gift, Juan Zhao of Intel has published a new Wayland Display Server patch-set for allowing full-screen mode-setting support.
The plethora of Wayland news continues. Here's a guide on how to run Qt applications within the Wayland Display Server for those not waiting until the 2012 onslaught begins.
While patches for multi-touch with the X.Org Server were only published this week, Intel has already been working on multi-touch support for the Wayland Display Server. On Friday they published a separate multi-touch implementation for Wayland.
There's some new year-end work going on in the land of Wayland following a mysterious event.
Patches have been published for Wayland today for an idle animation interface and implementation within its demo compositor. In other words, you can now have a working screensaver in Wayland.
For those wishing to follow the development of Wayland Display Server, there's some new progress to report on. This time it's about supporting screensavers under Wayland.
While we're at least a year away from seeing the Wayland Display Server play any semi-serious role in the Ubuntu stack, for Ubuntu 12.04 LTS there may actually be an experimental Wayland preview session available.
Intel's Juan Zhao has written and published some new documents on Wayland. In particular, a step-by-step guide for building and setting up Wayland under Ubuntu 11.04 and also a document briefly going over the Wayland architecture and API.
A number of months ago I wrote about plans for some of the Wayland code to be re-licensed under the LGPLv2. That didn't happen and now Kristian is looking at a new license for the Wayland reference code.
With the 2011 Google Summer of Code, we now know how the Gallium3D OpenCL state tracker and morphological anti-aliasing (MLAA) turned out, but how did the remote display capabilities for the Wayland Display Server evolve over the summer? It's something that hasn't yet been reported about on Phoronix.
Besides the exciting news last week that KDE has drawn up plans for Wayland in 2012, there's more good news in the land of this next-generation display server: the Google Chrome/Chromium web-browser is being ported to run on Wayland.
Since last month when reporting What's New In The Land Of Wayland, not much has changed. There's been a handful of commits pushed to the Git repositories and a few messages to the development list.
It's been a few weeks since really mentioning the Wayland Display Server at Phoronix (the last time was in June when XWayland and xf86-video-wlshm were released). It's not because development of this next-generation Linux display server has stalled, but there's been some progress made and overall just the lower level of activity during the summer months.
One of the Clutter tool-kit developers has announced a tiny Wayland compositor that was written and it provides support for multiple display emulation. This Wayland compositor is capable of emulating four displays and for now basically serves as a technical example.
The "still very experimental for the foreseeable future but promising" Wayland has been discussed more at UDS Budapest, on the mailing lists, and now this weekend in Berlin at LinuxTag.
Wayland was talked about this morning at the summit in Budapest. In particular, the outlook for Wayland in Ubuntu and Linaro. Separately, there's also X.Org notes from today's meetings.
Besides OpenWF support in Wayland being talked about and on the roadmap, another item that's been hotly discussed the past couple of days is about client side decoration support for the Wayland Display Server.
Besides the obvious requirements and demands of needing to design a display server that can fully replace the needs of the long-standing X Server, and making all the tool-kits and major software support running natively on Wayland, another inhibitor to Wayland's adoption has been its graphics driver requirements. In particular, Wayland requires kernel mode-setting, EGL (in place of a DRI2 requirement), in-kernel memory management (GEM), and 3D acceleration.
When Mark Shuttleworth announced last year that Ubuntu will eventually deploy Wayland instead of an X.Org Server with their new Unity Desktop, there were many mixed reactions. There were many Phoronix enthusiasts excited since this means replacing ancient X11 code with a brand new code-base designed around modern graphics technologies that takes advantage of KMS, OpenGL, etc. Others, however, were less excited since Wayland is still a work-in-progress. While Wayland has come a long way in recent months, it's still not as full-featured as an X.Org Server, but the features coming are beginning to trump the current capabilities of the X stack.
While proposals for this year's Google Summer of Code is quickly coming to an end, there's been a last minute proposal for the Wayland Display Server. This proposal is to work on a hot-replace server.
Martin Gräßlin has been making some very interesting advancements to KWin in the past year or so, after having issues with open-source Mesa drivers, this German developer has made this compositing window manager for the KDE Plasma desktop run on OpenGL ES 2.0 and even optional support for OpenGL 3.x. He wouldn't mind some help though, so this summer for KDE's involvement in Google's Summer of Code he has proposed three fairly interesting projects, two of which benefit KWin on Wayland.
If you're not following the many Linux development mailing lists out there, the latest major discussion surrounding the Wayland Display Server that's spanned the Wayland, DRI/DRM, and Fbdev mailing lists has been about using Wayland on "dumb frame-buffers", KMS vs. fbdev, and DRM drivers on embedded SoCs.
If you head on over to the Nokia Labs Qt Blog there is a post about "multi-process Lighthouse", which is worth reading. It's written by Jørgen Lind about how up until now Qt has lacked a multi-process client/server solution, but now they are looking for the Wayland Display Server to fill this void. Jørgen and other Qt developers ended up writing "Qt Compositor", which is a Nokia Labs project for making Qt-based Wayland compositors.
In recent days on the Wayland development mailing list there's been a discussion about a HPC (High Performance Compute) architecture for Wayland. A few interesting ideas have been brought up.
While there have been some battles waged recently between Canonical and GNOME developers over collaboration with regard to the Unity desktop shell and revenue sharing for purchases made within their online music store (even this morning with another post by Mark Shuttleworth), on a more positive and productive note: how's the Wayland plans coming along?
Canonical's Bryce Harrington has just announced he has uploaded a snapshot of the Wayland Display Server to the Universe repository for Ubuntu 11.04, a.k.a. the upcoming "Natty Narwhal" Linux release.
