Three weeks from today, the X.Org Developers' Conference, the annual meet-up of Linux graphics driver developers, will be taking place in Chicago. Here's the latest developments for this conference.
Rob Clark of Texas Instruments has proposed to X.Org developers that the DRI2 protocol be extended so that overlays can display video content, as a possible replacement to X-Video or for a client-side X-Video API on top of DRI2.
It's time for the 2011 Linux Graphics Survey on Phoronix. Since 2007 (see the 2007, 2008, 2009, and 2010 results) we have been running an annual Linux graphics survey. The purpose of this survey is to help graphics driver developers, software / application developers, and other organizations understand the hardware/software configurations and features currently being used by Linux desktop users. It's now time for the 2011 Linux Graphics Survey.
We're now just one month away from the 2011 X.Org Developers' Conference (XDC2011) that's being hosted in Chicago, Illinois, United States.
Keith Packard has tagged X.Org Server 1.11 RC2. The X.Org Server 1.11 release is imminent and the RC2 marks the end of development except for critical fixes.
One of the long sought after features of X.Org and the Linux graphics stack has been the ability to run multiple X Servers from a single graphics card. While this wouldn't be used by many, there are still many interested in seeing this feature request become a reality.
Lennart Poettering has published patches this Sunday to provide support for udev/systemd multi-seat input device hot-plugging support for the X.Org Server.
As I mentioned earlier this week on the X.Org mailing lists, there's just two months left until XDC2011, this year's X.Org Developers' Conference that I've been organizing. XDC2011 is taking place from the 12th to 14th of September in Chicago, Illinois, United States.
For anyone still relying upon non-kernel non-evdev non-synaptics input drivers for X.Org on Linux, there's a number of new releases. Peter Hutterer has released six updated xf86-input drivers.
Corentin Chary has announced the release of XWayland and the new xf86-video-wlshm driver.
Last week there was the release of a set of patches for X.Org that implement smooth-scrolling support for the X Server. These patches were released by Daniel Stone and today he's now released a set of patches that target the X.Org Synaptics input driver for implementing smooth scrolling, predictable motion, and better acceleration.
In early 2012 we can expect to see the release of X.Org Server 1.12 with various touch improvements and other input related work. Also being queued up for the 1.12 release is support for smooth scrolling.
Just returning back from a brief holiday, Keith Packard has tagged X.Org Server 1.11 Release Candidate 1.
Apple's Jeremy Huddleston has just released X.Org Server 1.10.2. This second point release was set to be released yesterday, but then there was fear of a regression causing a delay (turns out it's no longer reproducible), so now we have a holiday weekend release of xorg-server 1.10.2.
Even with the likely release of the Linux 3.0 kernel, open-source graphics drivers continue to be a big problem for the Linux desktop. While they have improved a lot in recent years, for many Linux users they can cause horrific headaches. Recently it was mentioned on Phoronix that Intel Sandy Bridge is in bad shape for Ubuntu 11.04 and that it even broke upstream in Linux 2.6.39, but Intel's far from being the only driver experiencing a choppy boat ride.
While not exactly uncommon for a major X.Org Server update, the video driver ABI for the DDX drivers will break with the forthcoming xorg-server 1.11 release. This means that for those using the proprietary graphics drivers, namely the AMD Catalyst driver, you may be stuck waiting a couple of months for support.
X Input 2.1 was originally talked about for X.Org Server 1.10 with its initial multi-touch implementation having been published back in late 2010.
Here's the next chapter of the X.Org / Mesa plans for Ubuntu 11.10, in continuation of the earlier X.Org / Mesa talks at UDS Budapest.
Announced just hours ago on the X.Org development mailing list is recent work to create the xf86-video-nested driver. As implied by the name of the driver and the title of this news post, this is an X.Org video driver designed to run nested X.Org servers. In other words, X.Org on top of X.Org.
As I just announced to the X.Org mailing lists (I'm the organizer of this year's event), the 2011 X.Org Developers' Conference is taking place in Chicago, Illinois from the 12 to 15th of September.
Jeremy Huddleston has tagged the first point release in the X.Org Server 1.10 series.
Patches have been presented on the X.Org development mailing list that provide a number of fixes and improvements to the ill-loved xf86-video-sis, the SiS X.Org driver.
While student registration for this year's Google of Summer of Code (GSoC) has not yet commenced, it's looking quite hopeful for the X.Org / Mesa work this summer. There was an OpenGL 4.1 state tracker that was proposed and some developers are calling this too ambitious. Just days ago there was then a multi-GPU PRIME and hot-switching proposal. This though is not the end of the list.
Last week a student developer from Belgium had proposed an OpenGL 4.1 state tracker for Gallium3D to be developed this summer as part of the X.Org / Mesa involvement with the annual Google Summer of Code. Under this proposal, OpenGL 4.1 would be implemented from scratch (Mesa / Gallium3D are currently only supportive of OpenGL 2.1 with limited support for OpenGL 3.0 extensions) without any dependence on Mesa; some of the well-known Mesa developers called this too ambitious, but it's unclear if the Belgian developer will still attempt this workload. Meanwhile, a Russian student developer has just voiced two ambitious proposals: Multi-GPU PRIME support and GPU hot-switching.
Summer is quickly approaching in the northern hemisphere so that means it's time for yet another year of Google's Summer of Code. Once again, X.Org / Mesa should be participating, so it's now time to submit ideas for areas where potential student developers could focus their summer work. Here's a few of the possibilities.
Besides laying out the plans for releasing X.Org Server 1.11 in August, Keith Packard has restarted the discussion surrounding RandR 1.4 so that it will hopefully be readied for integration into this next X Server release. It was part of X.Org Server 1.10 until the last minute when it was pulled from the server and caused a last minute video ABI break.
It seems as if the X.Org project has finally formed a habit of wanting to release on time. In years past, even point releases have been more than 200 days late and there hasn't been much to their release schedules that were actually executed on time. It's something I had long pointed out and have received jabs back in turn, but the past few X.Org Server releases have been tagged on time, plus or minus a few days. It looks like X.Org Server 1.11 may be another on-time release, it's at least being planned right out of the starting gate.
Tiago Vignatti has put out some statistics on the contributions to X.Org development during the X.Org Server 1.10 development cycle, to the xorg-server itself as well as the open-source drivers.
Last August we reported that Apple's lead X.Org engineer, Jeremy Huddleston, had stepped up to take over stable release management of the X.Org Server 1.9 series. The assumption was that Apple was planning to make X.Org Server 1.9.x available within their forthcoming Mac OS X 10.7 "Lion" operating system rather than the old X.Org Server 1.4 found with Mac OS X 10.6 "Snow Leopard". After trying out the latest Mac OS X 10.7 build, this is indeed the case.
X.Org Server 1.10 RC3 was barely out for 24 hours, but X.Org Server 1.10 was officially released on Friday evening by Keith Packard.
