While the Mir Display Server and the Wayland protocol are widely viewed as the next-generation display technologies for Linux systems, there's already been delays with Mir and Wayland hasn't yet been widely adopted. Even if/when Mir and Wayland manage to lift off, the X.Org Server won't suddenly die and will be supported for years to come.
The X.Org Developers' Conference (XDC) 2013 conference took place at the start of the week in Portland, Oregon. As usual, there's a number of Phoronix articles to go over in detail the many interesting presentations that took place this week concerning the X.Org Server, Mesa / Gallium3D graphics drivers, Mir, Wayland, and related Linux graphics initiatives.
It was nearly one year ago to the week that DRI3 (a.k.a. "DRI3000") was proposed during XDC2012. Now this week during XDC2013, Keith Packard has provided a status update on his pet project.
While most developers are focused around new innovations for Wayland (or Mir), there's still life ahead for the X.Org Server in maintaining legacy support and other cases where the xorg-server will not die for years to come. In improving the X.Org Server, Adam Jackson at Red Hat has been working on rewriting the GLX portion of the X.Org Server.
Mir was discussed briefly at this week's X.Org Developers' Conference by a Canonical employee.
Should the X.Org Foundation go ahead and be merged into a larger organization, they have their eyes on SPI.
While X.Org Server 1.15 was planned for release in September with the usual release cadence for X.Org updates, this isn't going to happen. X.Org Server 1.15 is going to be delayed until there's more interesting code merged.
One of the GSoC projects this summer for X.Org was implementing X-Video acceleration support using the OpenGL-based GLAMOR acceleration library.
For the X.Org Developers' Conference that's happening next week, XDC2013, the program of selected talks has now been announced.
There's just one week to go until the 2013 X.Org Developers' Conference gets underway in Portland, Oregon.
The experimental DRM render nodes support will be merged into the Linux 3.12 kernel. This work is a GSoC success story and makes it possible for Linux GPGPU compute support without needing an active display/compositor and ultimately for having multi-seat computing off a single display controller and another benefit is efficient compositor stacking.
The X.Org Foundation has lost its 501(c)(3) non-profit status and is now seeking new options, including possibly joining a larger organization.
The XPRA project provides a means of having "persistent remote application" support for X11 applications atop an X.Org Server. This allows for X applications to live on even if the connection to the server has been dropped.
For those curious about learning more information on Keith Packard's work for DRI3 (DRI3000), he presented at the 2013 DebConf and the video recording is now available.
With the ongoing X.Org work for DRI3, the latest revision to the Direct Rendering Infrastructure, there is a Present Extension, but it looks like a new name is needed.
While there's an X.Org 7.8 Wiki page that mentions planned features like XWayland integration and video driver hot-plugging, there isn't active work towards putting out the X.Org 7.8 katamari nor specifically on delivering these mentioned features.
The X.Org Developers' Conference is already coming up next month and there's a lot of interesting topics to be discussed from DRM security to Mesa to reverse-engineering NVIDIA GPUs.
Back-ends have been implemented for VDPAU to implement the video hardware-based decoding process over OpenGL and through Intel's VA-API interface, for those not using the NVIDIA binary blob or the VDPAU Gallium3D state tracker.
While Mir and Wayland are the future of Linux desktop display serving, X11 isn't going to magically disappear in the near-term. X.Org Server releases will keep coming for maintaining support for existing X11 clients, other alternative operating systems and environments where Wayland/Mir don't work, etc. With the X.Org Server still having a future, Keith Packard has been working on some improvements.
Canonical last week posted 15 patches so Mesa could support their Mir Display Server and specifically the Mir EGL platform. Those patches haven't received many comments from upstream Mesa developers, but there were more than 200 comments in our forums. Over the night, Canonical has posted X.Org Server patches for supporting XMir plus the open-source driver patches so it can handle XMir with nested compositing.
Video acceleration support for the GLAMOR library, the open-source way of accelerating 2D X.Org operations via the 3D engine, is still coming and is being worked on by a student this summer.
Keith Packard of Intel has managed to get an initial implementation of the DRI3 Present extension written and running for the X.Org Server.
David Herrmann has a GSoC project for working on DRM render and mode-set nodes and so far he has been making great progress. On Sunday he posted his second revision of his unified VMA offset manager patch-set and DRM render node work.
MicroXwin is an X.Org Server alternative for an X Windows System implementation for Unix/Linux desktop. The developers behind MicroXwin are claiming that by implementing their X Server in the kernel they are getting a 2x performance advantage while using less memory and being binary compatible with Xlib.
The X.Org Foundation has finally announced the details concerning the 2013 X.Org Developers' Conference.
Keith Packard has announced that the first of two new DRI3 (DRI3000) extensions for X.Org is working and the new extension can cooperate with the loading of the complete KDE and GNOME desktops.
The accepted Google Summer of Code 2013 projects concerning X.Org, Nouveau, and Mesa / Gallium3D is now known. There's some exciting stuff!
A pleasant and welcome change since this year's X.Org Foundation election is the return of meeting summaries for providing board members and the stakeholding desktop community with the results of each bi-weekly meeting.
The security researcher that uncovered a host of X.Org security issues went beyond just evaluating the X.Org libraries and looked at other Linux desktop packages too. There's many security-related bugs outstanding within the Linux desktop ecosystem and Ilja van Sprundel believes "things could be better by several orders of magnitude."
It was just last month that there was an X.Org Server security issue dealing with hot-plugging of input devices. Being announced today is a new round of security problems, this time multiple issues dealing with X.Org client libraries.
