An anonymous reader writes "It was revealed today during the annual X.Org Developers' Conference in Germany that NVIDIA will be publicly releasing Tegra graphics programming documentation. Initially this will cover their Tegra 2D engine but it's thought they might also be providing 3D engine documentation too. A slide shown at the conference says NVIDIA is committed to open-source. NVIDIA also allegedly has supplied documentation under NDA to one Nouveau developer and taken other covertly supportive steps. These actions come after NVIDIA has been notoriously unfriendly to open-source and months after Linus Torvalds pubilcly slammed the NVIDIA Linux support."

An anonymous reader writes "Presenting at the IEEE High Performance Extreme Computing conference, a researcher from the University of Tennessee presented evidence that the iPad 2 is as fast as the original Cray-2 supercomputer. Performance improvements were made to the iPad 2 LINPACK software by writing Python for generating and testing various Assembly routines. The researcher also found that the ARM Cortex-A9 easily beats the NVIDIA/AMD GPUs and latest Intel/AMD workstation CPUs in performance-per-Watt efficiency."

An anonymous reader writes "The widely used X11 Window System has turned 25 years old today. Version 11 of the X Window System is likely to remain in use for many years to come for backwards compatibility with the many legacy applications, BSD/Solaris systems, and Enterprise Linux distributions. Meanwhile, Wayland is still working to unseat the X Server for the common Linux desktop."

An anonymous reader writes "The NVIDIA Linux driver across multiple GeForce graphics cards can compete with Microsoft Windows 7 on Ubuntu, but only when using the KDE desktop and not the default Unity/Compiz. It turns out based upon recent desktop environment benchmarking, Ubuntu's Unity desktop is now noticeably slower than GNOME/KDE/Xfce/LXDE with multiple GPUs/drivers. Sam Spilsbury of Canonical/Compiz acknowledges the problem but it may take longer than one Ubuntu cycle to correct."

Mesa 3D has famously always not been technically OpenGL (lacking certification), but times are changing: "This is a great day for Mesa and open-source graphics drivers. Just a tad over a month ago, I submitted OpenGL ES 2.0 conformance test results to Khronos for Intel Sandy Bridge and Ivy Bridge GPUs with Mesa 8.0.4. There were no objections during the 30 day review period, so we are now officially conformant! Finally being on that list is pretty cool. Not only is this great news for my team at Intel, but it's terrific news for Mesa. Mesa has had a long history with OpenGL, the ARB, and Khronos. This is, however, the first time that Mesa has ever, in any way, been listed as a conformant implementation. This is a big boost to Mesa's credibility."

An anonymous reader writes "Intel's Open-Source Technology Center was given source-code access to Valve's Left 4 Dead 2 game in order to help them fix Linux bugs and to better optimize their graphics driver to this forthcoming Linux native game on the Source Engine. Intel has talked about their Valve Linux development experiences and now they managed to get Left 4 Dead 2 running on their open-source graphics driver. Valve also has grown fond of open-source hardware drivers: 'Valve Linux developers have also been happy looking at an open-source graphics driver. Valve Linux developers found it equally thrilling that now when hitting a bottleneck in their game or looking for areas for performance optimizations, they are simply able to look into Intel's open-source Linux graphics driver to understand how an operation is handled by the hardware, tossing some extra debugging statements into the Intel driver to see what's happening, and making other driver tweaks.'"

An anonymous reader writes "The BeOS-compatible Haiku OS operating system has been ported to x86_64. As part of the Google Summer of Code, a student made a 64-bit port of the kernel and user-space and it's now working. However, not all of the BeOS apps and drivers are yet working in 64-bit mode."

An anonymous reader writes "OS X 10.8 has been benchmarked against Ubuntu Linux with some interesting results. From the tests on a Apple Mac Mini and Apple MacBook Pro, OS X Mountain Lion was clearly superior when it came to the graphics performance, but the rest of the time the operating systems performed quite closely with no clear winner. OS X also seems to have greater performance issues with solid-state drives than Linux."

An anonymous reader writes "Phoronix reports on the progress of kmscon, David Herrmann's virtual console project that aims to supersede the Linux kernel's virtual terminal. kmscon takes advantage of modern Linux features such as kernel mode setting, direct rendering, and udev to provide hardware-accelerated rendering, full internationalization, monitor hot-plugging, and proper multi-seat support. A recent blog post by Herrmann addresses some of his frequently heard questions and criticisms about the kmscon project."

An anonymous reader writes "It turns out that Linux doesn't work too well on the Apple Retina MacBook Pro. Among the problems are needing special boot parameters to simply boot the Linux kernel, graphics drivers not working, no hybrid graphics support, WiFi requiring special firmware, Thunderbolt troubles, GNOME/Unity/KDE not being optimized for retina displays, and other snafus, including 20% greater power consumption with Linux over OS X. According to Michael Larabel, it will likely not be until early next year when most of the problems are ironed out for a clean 'out of the box' Linux experience on the Retina MacBook Pro."

An anonymous reader writes "The Wayland-usage in Ubuntu 12.10 via setting it up as a system video compositor has been delayed to at least Ubuntu 13.04. Developers made progress on running Ubuntu on Wayland (there are experimental packages available), but they need more time to complete their work and ready Wayland. For those wanting to try out Wayland on Linux, there is a specialty Wayland LiveCD."

An anonymous reader writes "The default desktop within Debian 7.0 'Wheezy' has changed from GNOME to Xfce. GNOME, KDE, and LXDE will continue to be available, but the decision was made to default to Xfce. The reported reasoning comes down to size constraints in fitting GNOME on a single CD."

An anonymous reader writes "One day after word leaked out that Nokia is shutting down its Qt Australia office, which is responsible for Qt3D, QtDeclarative, QtLocation, QtMultimedia, QtSensors, and QtSystems, reports are beginning to surface that Nokia is trying to sell off all Qt assets." Seems like selling itself to Nokia wasn't the best option for Trolltech after all.

rms has published his thoughts on Steam coming to GNU/Linux. He notes that the availability of proprietary games may very well help spread GNU/Linux (but the FSF prioritizes spreading software freedom). And, you're better off at least having a Free operating system instead of Windows: "My guess is that the direct good effect will be bigger than the direct harm. But there is also an indirect effect: what does the use of these games teach people in our community? Any GNU/Linux distro that comes with software to offer these games will teach users that the point is not freedom. Nonfree software in GNU/Linux distros already works against the goal of freedom. Adding these games to a distro would augment that effect." Or: How will the FOSS community affect Valve? Already they've contributed a bit to the graphics stack, hired a few folks from inside the community, etc. But Steam also makes use of DRM and distributes software in ways that are opposed to the ideals of many in the FOSS community (and even the wider Free Culture community). Given Gabe Newell's professed love for openness, might we see their company culture infiltrated?

An anonymous reader writes "It looks like Valve's Linux team that's still growing has found much interest in open-source graphics drivers. Intel Linux graphics driver developers and Valve's Linux team were meeting for the past week to look at each other's code, work out performance goals, and collaborate on new features. Ian Romanick of Intel blogs, 'The funny thing is Valve guys say the same thing about drivers. There were a couple times where we felt like they were trying to convince us that open source drivers are a good idea. We had to remind them that they were preaching to the choir. :) Their problem with closed drivers (on all platforms) is that it's such a blackbox that they have to play guess-and-check games. There's no way for them to know how changing a particular setting will affect the performance. If performance gets worse, they have no way to know why. If they can see where time is going in the driver, they can make much more educated guesses.' Perhaps the companies are paying attention to Linus Torvalds' memo to NVIDIA?"

An anonymous reader writes "Valve Software, in their Linux Steam / Source Engine effort, plus the rumored Steam Box, is continuing to hire top Linux developers. So far they have poached the lead developers of the DarkPlaces open-source engine used by Nexuiz/Xonotic, the founder of Battle for Wesnoth, and just yesterday they hired Sam latinga, creator of Simple DirectMedia Layer. According to Michael Larabel, they are still trying to hire more Linux kernel developers, driver experts, and other 'extremely talented Linux developers.'"

jones_supa writes "While there's still more than one month until the Ubuntu 12.10 feature freeze, Ubuntu developers continue to work towards their tight schedule of having Wayland serve as the compositor for the Quantal Quetzal release due out in October. Canonical's intends to provide smooth transitions from boot to shutdown. Wayland is also used for session switching and other operations, avoiding traditional VT switching, providing a consistent monitor layout, using the greeter as the lock screen, ensuring that locked sessions are actually secure from displaying, and showing the greeter while the session loads. Phoronix remains skeptical about Ubuntu making the deadline."

An anonymous reader writes "ARM Holdings has made available Linux kernel support for AArch64, the ARMv8 64-bit architecture. No 64-bit ARMv8 hardware is yet shipping until later this year, but ARM has prepared the 36 patches amounting to 23,000 lines of architecture code for mainline integration."

An anonymous reader writes "Mozilla will be announcing next week that they will effectively be taking away resources from Thunderbird's development. Mozilla believes it's better for the developers behind the open-source e-mail client to work on other projects, i.e. Firefox OS. They claim they will not be outright stopping Thunderbird." You can also read the letter at pastebin.

An anonymous reader writes "The GNU C Library version 2.16 was released with many new features over the weekend. The announcement cites support for the Linux x32 ABI, ISO C11 compliance, performance improvements for math functions and some architectures, and more than 230 bug fixes."

An anonymous reader writes "After being in development for more than a decade, GRUB2 was released today as stable. The mailing list announcement covers new features including a standard theme, support for new file-systems, ports to new CPU architectures, new driver coverage, better EFI support, and many other new features that have materialized over the years of development to succeed GRUB Legacy."

An anonymous reader writes "Peter Penz has been a user of KDE since version 1.2, and he led the development of the Dolphin file manager for the past six years. Now, he's quitting KDE development and handing off Dolphin. His reasons for quitting KDE development are described in a blog post. Penz speaks of KDE losing competitiveness to Apple and Microsoft due to increased complexity and other reasons. 'Working on the non-user-interface parts of applications can be challenging, and this is not something that most freetime-contributors are striving for. But if there are not enough contributors for the complex stuff behind the scenes and if no company is willing to invest fulltime-developers to work on this... well then we are losing ground.' Are open-source desktops losing?"

An anonymous reader writes "The Ivy Bridge graphics processor from Intel is now fully documented under the Creative Commons. Intel released four volumes of documents (2400+ pages) covering their latest graphics core as a complete programming guide with register specifications. Included with the graphics documentation is their new execution unit and video engine."

An anonymous reader writes "It's not only the NVIDIA Linux driver that has been publicly slammed over lacking support; the AMD Catalyst driver is now facing scrutiny from developers of the XBMC media and entertainment software. The developers aren't happy with AMD due to not properly supporting video acceleration under Linux. The AMD Linux driver is even lacking support for MPEG2 video acceleration and newer levels of H.264. AMD reportedly has the support coded, but they're refusing to turn it on in their public Linux driver."

An anonymous reader writes "Canonical has laid out their plans for handling UEFI SecureBoot on Ubuntu Linux. Similar to Red Hat paying Microsoft to get past UEFI restrictions, Canonical does have a private UEFI key. Beyond that they will also be switching from GRUB to the more liberal efilinux bootloader, and only require bootloader binaries be signed — and they want to setup their own signing infrastructure separate from Microsoft."

An anonymous reader writes "According to Phoronix, AMD will be open-sourcing its Linux execution and compiler stack as part of jump-starting the Heterogeneous System Architecture Foundation. The HSA Foundation was started earlier this month at the AMD Fusion Developer Summit and AMD plans to open up its stack so that others can utilize the code without causing HSA fragmentation. This will include LLVM code, the HSA run-time, an HSA kernel driver for Linux distributions, an HSA assembler, and other components."

jones_supa writes "NVIDIA's PR department has issued a statement following the harsh comments by Linus Torvalds last week where he referred to the graphics company as the single worst company he's ever dealt with, called them out on not supporting Optimus, and other issues. Basically the company replied they're committed to Linux using their proprietary driver that is largely common across platforms, and this allows for same-day Linux support with full OpenGL implementation. They also say that they're active in ARM Linux for Tegra and support a wide range of hardware under Linux. Despite having not made any commitment to better support Optimus under Linux nor providing technical assistance to the Nouveau community, NVIDIA assures us that 'at the end of the day, providing a consistent GPU experience across multiple platforms for all of our customers continues to be one of our key goals.'"

An anonymous reader writes "Phoronix constructed a low-cost, low-power 12-core ARM cluster running Ubuntu 12.04 LTS and made out of six PandaBoard ES OMAP4460 dual-core ARMv7 Cortex A9 chips. Their results show the ARM hardware is able to outperform Intel Atom and AMD Fusion processors in performance-per-Watt, except it sharply loses out to the latest-generation Intel Ivy Bridge processors." This cluster offers a commendable re-use of kitchenware. Also, this is a good opportunity to recommend your favorite de-bursting tools for articles spread over too many pages.

An anonymous reader writes "Shared in last quarter's FreeBSD status report are developer plans to have LLVM/Clang become the default compiler and to deprecate GCC. Clang can now build most packages and suit well for their BSD needs. They also plan to have a full BSD-licensed C++11 stack in FreeBSD 10." Says the article, too: "Some vendors have also been playing around with the idea of using Clang to build the Linux kernel (it's possible to do with certain kernel configurations, patches, and other headaches)."

dartttt writes "There was a very interesting session at the Ubuntu Developer Summit by Google developer Thomas Bushnell. He talked about how Ubuntu, its derivatives and Goobuntu (Google's customized Ubuntu based distro) are used by Google developers. He starts by saying 'Precise Rocks,' and that many Google employees use Ubuntu — including managers, software engineers, translators, people who wrote the original Unix, and people who have no clue about Unix. Many developers working on Chrome and Android use Ubuntu. Ubuntu systems at Google are upgraded every LTS release. The entire process of upgrading can take as much as four months, and it is also quite expensive, as one reboot or a small change can cost them as much as a million dollars across the company." Bushnell also mentions that Google Drive will soon be available for Linux. Other news out of UDS: there was discussion of a GNOME flavor of 12.10, Electronic Arts reaffirmed that they "won't delay their Windows work for Linux," and Unity 2D is likely to disappear in 12.10.

An anonymous reader writes with an excerpt from Phoronix: "Chris Kenyon, the VP of sales and business development for Canonical, just spoke this afternoon at the Ubuntu 12.10 Developer Summit about what Canonical does with OEMs and ODMs. He also tossed out some rather interesting numbers about the adoption of Ubuntu Linux. Namely, Ubuntu will ship on 5% of worldwide PC sales with a number of 18 million units annually."

An anonymous reader writes "Valve's Steam and Source Engine-based games are coming to Linux. Michael from well known site Phoronix.com has been invited to Valve's office and was able to spend a day with the developers and Gabe Newell himself. He is confirming the rumors about Linux ports from Valve, and has been able to play the games and work the developers himself. Attached in the article are pictures from Valve's offices with games running on Linux."

nukem996 writes "After initially reporting in 2010 that Valve was working on a native GNU/Linux client, one has finally been confirmed. Michael Larabel recently visited Valve's Bellvue, WA based office and has been able to see it himself. Included in the article are screenshots of the client running and speculation of a release." Valve has yet to officially comment, but you'd hope they wouldn't invite someone up to their offices and send them home to spew lies.

An anonymous reader writes "Not being content with the state of open source graphics drivers for Linux, a developer working for Texas Instruments has reverse-engineered his competitor's (Qualcomm) driver and written an open-source Snapdragon driver. With being tainted by legal documents at Texas Instruments, the developer, who is also involved with Linaro, had no other choice but to work on an open source graphics driver for his competitor in his free time. The open source Qualcomm Snapdragon/Adreno driver is called Freedreno."

An anonymous reader writes "The open source Nouveau driver, a reverse-engineered incarnation of NVIDIA's official proprietary driver for Linux, has reached its biggest milestone. The Nouveau driver is now being considered stable within the Linux kernel and leaving the staging area, with the pledge of a stable ABI. Phoronix has summarized the state of the Nouveau driver, which works fine if you don't care about performance or are fine with running hardware that's a few generations old."

Phoronix was at the Linux Foundation Collaboration Summit and has two articles on the status of Wayland and X11 integration. The second talk was about the current status of Wayland, and its impending release (version 1.0 is due this summer). The developers also have an experimental GNOME-Shell working on Wayland. There's a (kind of shaky) video of this talk (attached, and at youtube for those wanting the html5 version). The first talk (by Keith Packard) covered X11 support on Wayland. It's basically ready to go, but window management is implemented only as a hack right now. The next year could be quite exciting for GNU/Linux and BSD users as distributions begin including Wayland as an alternative to X.org.

crookedvulture writes Nvidia has lifted the curtain on reviews of its latest GPU architecture, which will be available first in the high-end GeForce GTX 680 graphics card. The underlying GK104 processor is much smaller than the equivalent AMD GPU, with fewer transistors, a narrower path to memory, and greatly simplified control logic that relies more heavily on Nvidia's compiler software. Despite the modest chip, Nvidia's new architecture is efficient enough that The Tech Report, PC Perspective, and AnandTech all found the GeForce GTX 680's gaming performance to be largely comparable to AMD's fastest Radeon, which costs $50 more. The GTX 680 also offers other notable perks, like a PCI Express 3.0 interface, dynamic clock scaling, new video encoding tech, and a smarter vsync mechanism. It's rather power-efficient, too, but the decision to focus on graphics workloads means the chip won't be as good a fit for Nvidia's compute-centric Tesla products. A bigger GPU based on the Kepler architecture is expected to serve that market." Read on below for good news (at least if you prefer Free software) from an anonymous reader. Update: 03/22 19:35 GMT by T : Mea culpa -- that headline should say "Kepler," rather than Fermi; HT to Dave from Hot Hardware (here's HH's take on the new GPU). Our anonymous friend writes "The open-source Nouveau driver project that reverse-engineers the official NVIDIA driver to provide a free software alternative has made some big accomplishments. Nouveau announced today they have same-day Kepler support and are now de-staging on Linux. The GeForce GTX 680 'Kepler' launch just happened hours prior to Nouveau, somehow managing initial mode-setting support with early hardware, from a project that NVIDIA 'officially' does not support. The de-staging in the Linux kernel now means that the driver is at version 1.0 with a stable ABI."

An anonymous reader writes "AMD has publicly released the open-source code to the Radeon HD 7000 series 'Southern Islands' graphics cards for Linux users. This allows users of AMD's latest-generation of Radeon graphics cards to use the open-source Linux driver rather than Catalyst, plus there's also early support for AMD's next-generation Fusion APUs."

Norsefire writes "NVIDIA is joining the Linux Foundation, along with three other to-be-announced companies. From the article: 'As one of the three big makers of graphics chips for PCs--the other two are Intel and AMD, both of which are longtime Linux Foundation members--Nvidia's increased participation in Linux could be big news for users of the free and open source operating system. Nvidia has long taken a closed approach to Linux drivers for its graphics cards, offering only a proprietary one and declining to participate in the open source Nouveau driver project, which has depended instead on reverse engineering.'"

An anonymous reader writes "The KWin window manager maintainer for KDE is looking at removing the legacy OpenGL 1.0 renderer from the KWin code-base due to the costs of supporting legacy hardware. This means dropping support for non-GL2+ graphics cards, which are all over six years old, but in the process would mean that for now there is no longer any support for the AMD Catalyst driver on the KDE desktop. Due to driver bugs, AMD's proprietary Catalyst software only works well with the GL1 renderer even though their latest hardware supports OpenGL 4."

An anonymous reader writes "The Nouveau driver project that's been writing an open-source NVIDIA graphics driver via reverse-engineering has moved forward in their support. The Nouveau driver now has OpenCL acceleration support to do GPGPU computing on the open-source community driver for several generations of GeForce GPUs."

An anonymous reader writes "The CEO of the once fledging Linux Game Publishing, Michael Simms, has announced his resignation. Simms attributes his resignation from the Linux game porting company he founded more than a decade ago to being burned out and having little success as of late in his work." In his place, Clive Crouse will be taking the helm.
