An anonymous reader writes "In a 15-way graphics card comparison on Linux of both the open and closed-source drivers, it was found that the open-source AMD Linux graphics driver is much faster than the open-source NVIDIA driver on Ubuntu 13.04. The open-source NVIDIA driver is developed entirely by the community via reverse-engineering, but for Linux desktop users, is this enough? The big issue for the open-source 'Nouveau' driver is that it doesn't yet fully support re-clocking the graphics processor so that the hardware can actually run at its rated speeds. With the closed-source AMD Radeon and NVIDIA GeForce results, the drivers were substantially faster than their respective open-source driver. Between NVIDIA and AMD on Linux, the NVIDIA closed-source driver was generally doing better than AMD Catalyst."

An anonymous reader writes "With the latest development work on Clang ahead of the release of LLVM version 3.3, Clang is now C++11 feature complete. The last remaining features of the ISO C++11 feature specification have been implemented. C++11 support for GCC is also more or less complete."

An anonymous reader writes "Six months after the release of Wayland 1.0, versions 1.1 of Wayland and Weston have been released. Wayland/Weston 1.1 brings new back-end support for the Raspberry Pi, Pixman renderer, Microsoft Remote Desktop Protocol (RDP), and FBDEV frame-buffer device. Wayland/Weston 1.1 also introduces a modules SDK, supports the EGL buffer-age extension, touch-screen calibration support, and numerous optimizations and bug-fixes."

An anonymous reader writes "Intel has released its first version of Beignet, an open-source OpenCL run-time and LLVM back-end for Linux that uses LLVM/Clang and is compatible with Ivy Bridge processors. Right now there's partial support for OpenCL 1.0 and 1.1 along with other basic functionality." This is not using Gallium 3D, and at least David Arlie thinks it should not be an fd.o project because it duplicates functionality already present in Mesa.

An anonymous reader writes "A Jolla Sailfish OS engineer has ported Wayland to run on Android GPU drivers. The implementation uses libhybis with the Android driver so that the rest of the operating system can be a conventional glibc-based Linux operating system, such as Mer / Sailfish OS. The code is to be LGPL licensed. The reported reasoning for making Wayland support Android GPU drivers was difficulty in ODM vendors not wishing to offer driver support for platforms aside from Android."

An anonymous reader writes "Nearly one year after Linux creator Linux Torvalds publicly bashed NVIDIA and several years after their multi-GPU mobile technology premiered, the graphics vendor has finally delivered an Optimus-supported Linux driver. NVIDIA released the 319.12 Beta Linux driver that brings support for 'RandR 1.4 GPU provider objects' that basically allows for Optimus-like functionality when using the latest X Server, Linux kernel, and XRandR. The 319.12 beta also has many other features including better UEFI support, installer improvements, new pages on their settings panel, and new GPU support."

New submitter linatux writes "HP has announced their 'Moonshot 1500 server' — up to 1,800 servers per 47U rack are supported. The tech certainly seems to be an advance on what is currently available — will it be enough to revive HP's server fleet?" From Phoronix: "Moonshot began with Calxeda-based ARM SoCs, but in the end HP settled for Intel Atom processors. Released today were HP's Moonshot system based on the Intel Atom S1200. Hewlett-Packard claims that their Moonshot System uses 89% less energy, 80% less space, 77% less cost, and 97% less complexity than traditional servers."

An anonymous reader writes "Linux developers are now working on open-source 3D support for NVIDIA's Tegra in cooperation with NVIDIA and months after the company published open-source 2D driver code. There are early patches for the Linux kernel along with a Gallium3D driver. The Tegra Gallium3D driver isn't too far along yet but is enough to run Wayland with Weston."

New submitter Skrapion writes "One month ago, an independent developer submitted patches to the Wayland's Weston compositor which adds support for FreeRDP, an open-source remote desktop protocol. Now, after six revisions, the remote desktop code has been merged into the trunk. While remote desktop has been prototyped in Weston once before by Wayland developer Kristian Høgsberg, this is the first time Wayland/Weston has officially supported the feature. For a summary of why we can expect Wayland's remote desktop to surpass X.Org's network transparency, see Daniel Stone's excellent talk from Linux.conf.au."

An anonymous reader writes "Years of desire by AMD Linux users to have open source video playback support by their graphics driver is now over. AMD has released open-source UVD support for their Linux driver so users can have hardware-accelerated video playback of H.264, VC-1, and MPEG video formats. UVD support on years old graphics cards was delayed because AMD feared open-source support could kill their Digital Rights Management abilities for other platforms."

An anonymous reader writes "In preparation for the "Steam Box" game console that will make necessary their own Linux-based software platform, Valve developers have started publishing Debian packages for their platform which looks like their first-generation operating system will be derived from Ubuntu 12.04.2 LTS. So far the packages being published include a new "Plymouth" boot splash screen as the operating system loads, a Steam desktop wallpaper, auto-updating system scripts, and experimental NVIDIA Linux graphics drivers."

An anonymous reader writes "Weeks after Canonical announced Mir, Wayland's display server protocol and Weston compositor have been forked. A contributor to Wayland found differing views with the project over desktop eye candy and other technical decisions to the X11 successor, which resulted in forming the Northfield and Norwood projects. The developer, Scott Moreau, has been outted from the project but has provided a lengthy explanation why the fork was needed to advance the Linux desktop."

An anonymous reader writes "Canonical's plan to develop the Mir Display Server for Ubuntu rather than going with their original plans to adopt Wayland has been met with criticism from KDE (and other) developers... The GNOME response to Ubuntu's Mir is that they will now be rushing support for the GNOME desktop on Wayland. Over the next two release cycles they plan to iron out the Wayland support for the GNOME Shell, the GTK+ toolkit, and all GNOME packages so that by this time next year you can be running GNOME entirely on Wayland while still having X11 fall-back support."

An anonymous reader writes "On the Ubuntu Wiki is now the Mir specification, which is a next-generation display server not based on X11/X.Org or Wayland. Canonical is rolling their own display server for future releases of Ubuntu for form factors from mobile phones to the desktop. Mir is still in development but is said to support Android graphics drivers, open-source Linux graphics drivers, and they're pressuring hardware vendors with commercial closed-source drivers to support it too. They also said X11 apps will be compatible along with GTK3 and Qt/QML programs. Canonical isn't using X11 or Wayland with their future Unity desktop as they see many shortcomings from these existing and commonly used components."

An anonymous reader writes "With work done by ARM and Linaro, there is now a bootable image of Debian/Ubuntu that works for ARM64, the new 64-bit ARM architecture. There are still some caveats and work ahead, but Linux is once again the first platform that has software ready to run on a new architecture when released. This 64-bit ARM Linux support also includes the ability to run 32-bit ARM software side-by-side." You can grab a bootable rootfs, but there's no hardware to actually run it on now (the developers are using the free-as-in-beer simulator from ARM). Kernel support for the architecture was released around a year ago; this is more a tale of getting from a bootable kernel to a bootable operating system.

An anonymous reader writes "The first release candidate of Debian Installer 7.0 Wheezy was released this week.

sfcrazy writes "KDE's Plasma Active team leader Aaron Seigo has raised some concerns around Ubuntu Phone. He says 'We can start with the obvious clue: Unity currently does not use QML at all; Ubuntu Phone is pure QML. So, no, it is not the same code, it is not the sort of seamless cross-device technology bridge that they are purporting.' He then concludes, 'If you're a Free software developer, user and/or supporter and buying into these claims, I don't know how else to put it other than this: you're being duped. Consider what supporting those who employ such tactics means for Free software.'"

An anonymous reader writes "NetBSD 7.0 will support the Lua scripting language within its kernel for developing drivers and new sub-systems. A Lua scripting interpreter is being added to the NetBSD kernel along with a kernel API so developers can use this scripting language rather than C for developing new BSD kernel components. Expressed reasons for supporting a scripting language in a kernel were rapid application development, better configuration, and "modifying software written in C is hard for users." In a presentation it was said that Lua in the kernel will let users explore their system in an easy way."

An anonymous reader writes "The Khronos Group has published the first products that are officially conformant to OpenGL ES 3.0. On that list is the Intel Ivy Bridge processors with integrated graphics, which support OpenGL ES 3.0 on open-source Linux Mesa. This is the best timing yet for Intel's open-source team to support a new OpenGL standard — the standard is just six months old whereas it took years for them to support OpenGL ES 2.0. There's also no OpenGL ES 3.0 Intel Windows driver yet that's conformant. Intel also had a faster turn-around time than NVIDIA and AMD with the only other hardware on the list being Qualcomm and PowerVR hardware. OpenGL ES 3.0 works with Intel Ivy Bridge when using the Linux 3.6 kernel and the soon-to-be-out Mesa 9.1." Phoronix ran a rundown of what OpenGL ES 3.0 brings back in August.

An anonymous reader writes "Hurd, the GNU micro-kernel project that was founded by Richard Stallman in 1983, may finally be catching up with Linux on the desktop... Plans were shared by its developers to finally bring in some modern functionality by working on support for Serial ATA drives, USB support, and sound cards. There are also ambitions to provide x86-64 CPU architecture support. GNU Hurd developers will be doing an unofficial Debian GNU/Hurd 'Wheezy' release this year but they hope for the Debian 'Jessie' release their micro-kernel in Debian will make it as part of some official CDs."

jones_supa sends this quote from Phoronix: "David Herrmann has provided an update on his ambitious initiative to kill off the Linux kernel console. Herrmann has long been working on making the Linux kernel CONFIG_VT option unnecessary for providing a Linux console by punting it off to user-space. The Linux kernel VT console hasn't been changed much in the past two decades and Herrmann is hoping to see it replaced with a user-space solution he's been developing that would allow for multi-seat support, a hardware-accelerated console, full internalization, and other features."

An anonymous reader writes "The hardware hasn't been released yet, but AMD has made available early open-source Linux GPU driver patches for supporting the future Radeon HD 8000 series graphics cards. At this time the Radeon HD 8800 'Oland' series is supported with the Mesa, DRM, X.Org, and kernel modifications. From the driver perspective, not many modifications are needed to build upon the Radeon HD 7000 series support."

SternisheFan sends this quote from ZDNet: "Software that allows Windows apps to run on Android devices was demoed at the Fosdem 2013 open source conference this weekend. The demo by Alexandre Julliard, one of the original developers of Wine, showed Wine running on an emulated Android environment. Phoronix reports the performance of Wine on Android to be 'horrendously slow' but says these problems were attributed to it running on an emulated environment rather than a native Android OS. ... The makers claim it bypasses many performance and memory penalties of other methods for simulating computing environments, such as running virtual machines, by translating Windows API calls into POSIX calls on the fly. The Android OS predominantly runs on ARM-based devices today, and a separate demo at the Fosdem conference showed Wine running on ARM-based hardware. There was no news on when support for ARM-based devices or Android will be added to a publicly available Wine release."

An anonymous reader writes "Linux kernel developer veteran Alan Cox has lashed out at Red Hat's recent release of Fedora 18. Cox posted comments to his Google+ page saying 'Fedora 18 seems to be the worst Red Hat distro I've ever seen.' He encountered numerous problems with Fedora 18 and then decided to switch to Ubuntu."

Titus Andronicus writes "fuse-exfat, a GPLv3 implementation of the exFAT file system for Linux, FreeBSD, and OS X, has reached 1.0 status, according to an announcement from Andrew Nayenko, the primary developer. exFAT is a file system designed for sneaker-netting terabyte-scale files and groups of files on flash drives and memory cards between and among Windows, OS X, and consumer electronics devices. It was introduced by Microsoft in late 2006. Will fuse-exfat cut into Microsoft's juicy exFAT licensing revenue? Will Microsoft litigate fuse-exfat's developers and users into patent oblivion? Will there be a DKMS dynamic kernel module version of the software, similar to the ZFS on Linux project? All that remains to be seen. ReadWrite, The H, and Phoronix cover the story."

An anonymous reader writes "The Arch Linux distribution has been modified to run off the FreeBSD 9.0 kernel as an alternative to using Linux. The developer of Arch BSD explained his reasoning as enjoying FreeBSD while also liking the Arch Linux philosophy of a 'fast, lightweight, optimized distro,' so he sought to combine the two operating systems to have FreeBSD at its core while being encircled by Arch. The Arch BSD initiative is similar to Debian GNU/kFreeBSD."

An anonymous reader writes "Red Hat developers are planning to replace MySQL with MariaDB in Fedora 19. For the next Fedora update, the MariaDB fork would replace MySQL and the official MySQL package would be discontinued after some time. The reasoning for this move is the uncertainty about Oracle's support of MySQL as an open-source project and moves to make the database more closed." Update: 01/22 13:47 GMT by T : Note: "Nixing" may be a bit strong; this move has been proposed, but is not yet officially decided.

It looks like the recent success of Linux gaming has caught Blizzard's eye. According to "a reliable source at the company" 2013 will be the year that "at least one of their very popular titles will see a release for Ubuntu Linux." From the article: "It's been a poorly-kept secret that Blizzard has a native Linux client of World of Warcraft. As recently as 2011, the World of Warcraft Linux client was still being maintained internally. The client has been around for years and done by their own developers as a form of testing for the popular MMORPG currently offered on Windows and Mac OS X. As for why they haven't released the client, it's come down to "targeting a specific version of the platform" with Linux being "unstandardized" due to the many different distributions. There's still some fundamental problems with gaming on Linux. With World of Warcraft working generally fine under Wine as well, the company is further unmotivated to officially support a Linux build of the game."

An anonymous reader writes "It's been found that the Btrfs file-system is vulnerable to a Hash-DOS attack, a denial-of-service attack caused by hash collisions within the file-system. Two DOS attack vectors were uncovered by Pascal Junod that he described as causing astonishing and unexpected success. It's hoped that the security vulnerability will be fixed for the next Linux kernel release." The article points out that these exploits require local access.

An anonymous reader writes "After having Wine to run Windows binaries on Linux, there is now the Darling Project that allows users to run unmodified Apple OS X binaries on Linux. The project builds upon GNUstep and has built the various frameworks/libraries to be binary compatible with OSX/Darwin. The project is still being worked on as part of an academic thesis but is already running basic OS X programs."

Via Phoronix comes a link to an interview with prolific GNU/Linux game porter Icculus about the state of gaming on GNU/Linux. Topics include Steam, Windows 8, his experiences trying to push FatELF vs full screen games, and the general state of the game industry. From the article (on the general state of games on GNU/Linux): "It's making progress. We're turning out to have a pretty big year, with Unity3D coming to the platform, and Valve preparing to release Steam. These are just good foundations to an awesome 2013."

An anonymous reader writes "The Google Samsung Chromebook was already interesting for its competitive $250 price-tag and that it can be loaded with Linux distributions beyond Chrome OS, but it turns out that its performance is particularly good, too. When loaded with Ubuntu Linux, the Samsung Exynos 5 Dual ARM SoC on the Chrome notebook had outperformed a 1.8GHz Intel Atom, a quad-core Calxeda ARM server, and a TI OMAP4 PandaBoard."

New submitter skade88 writes "With the Linux Steam beta giving Ubuntu and its large userbase all the love, other Linux gamers understandably want to be let in on the fun. For the beta, Valve has provided Steam as a Debian package. Many hungry Linux gamers have reported that they have Steam running on their favorite distro, but that still leaves the legal debate. What is the legal threshold needed to get Steam in the repos of your preferred flavor of Linux? Will Valve's one-size-fits-every-OS license be flexible to work on Linux or will it delay the dream of a viable gaming world for Linux? We are so close to bridging the last major hurdle in finally realizing the year of the Linux desktop: Gaming. Lets hope the FOSS community and Valve can play together so we all win."

An anonymous reader writes "Via LXer, an article at Phoronix tells of GNOME's plans to eliminate 'fallback mode' (GNOME classic) in the 3.8 release."

jones_supa writes "The SDL developers Ryan Gordon and Sam Lantinga have proposed a window manager change to work out the full-screen X11 window mess, primarily for games. The proposal is to come up with a _NET_WM_STATE_FULLSCREEN_EXCLUSIVE window manager hint that works out the shortcomings of the full-screen hint used currently by most games, _NET_WM_STATE_FULLSCREEN. Ryan and Sam have already worked out an initial patch for SDL but they haven't tried hooking it to any window manager yet. Those interested in the details, information is available from this mailing list message. One of the key changes is that software would make the request to the window manager to change the resolution, rather than tapping RandR or XVidMode directly. Martin Gräßlin of KDE was rather wary about the patch and said that games changing the resolution just tend to mess up the desktop." Seems like a reasonable idea, given a bit of time to mature as a spec. In KDE's case, a separate daemon from the window manager handles resolution changes so going through the WM would add complexity, and the plasma shell still has no way to realize that it shouldn't reflow the desktop widgets. Setting window properties seems like a sensible IPC method for communicating intent though (without making yet another aspect of the X desktop reliant upon the not-very-network-transparent dbus): "hey, I need to resize, but just for me so don't reshuffle the desktop and docks."

An anonymous reader writes "An EXT4 file-system data corruption issue has reached the stable Linux kernel. The latest Linux 3.4, 3.5, 3.6 stable kernels have an EXT4 file-system bug described as an apparent serious progressive ext4 data corruption bug. Kernel developers have found and bisected the kernel issue but are still working on a proper fix for the stable Linux kernel. The EXT4 file-system can experience data loss if the file-system is remounted (or the system rebooted) too often."

An anonymous reader writes "Modern Linux desktops like Ubuntu's Unity and the GNOME Shell have placed a requirement on OpenGL 2.0+ support for handling their compositing window managers and desktop effects. Wayland's Weston also needs OpenGL ES 2.0 support. Now with modern Linux distributions like Ubuntu 12.10, rather than falling back to a 2D unaccelerated desktop if you don't have a sufficient GPU or graphics driver, users are being forced to run LLVMpipe as a CPU-based software rasterizer. LLVMpipe works fine if you are on a new PC with a fast x86-64 CPU, but the OpenGL-based Linux desktops are causing growing pains for ARM hardware, virtual machines, servers, multi-seat computers, and of course all older hardware. LLVMpipe is a Mesa Gallium3D driver that uses LLVM for run-time code generation as an attempt at accelerating graphics faster on the CPU. So much for Linux being good for old computers?" The KMS based graphics stack is already effectively unusable on AGP systems (if you have SMP + AGP, there are race conditions somewhere leading to really hard crashes that appeared a couple of years ago and dozens of years old open bugs with no resolution other than "use PCI mode" which cuts bus bandwidth by 4 or 8 times, and still doesn't work with SMP), but for those with older PCIe/IGP systems you could always runs Window Maker, Sawfish, Enlightenment, Open Box, or one of many other window managers without a compositor. Of course then you lose compositing, and there aren't any usable external compositors for some reason. The flipside to this is that moving to OpenGL as the primary interface to the GPU means one fewer driver that has to be written, and will probably lead to an overall improved experience for those with supported hardware given the limited resources Free Software drivers authors have.

An anonymous reader writes "After being talked about for four years, Wayland 1.0 was released today. The Wayland 1.0 release doesn't mark it yet as being ready for Linux desktop usage but just being API/protocol stable for future expansion. Wayland will now maintain backwards compatibility going forward, but how much longer will it take to replace X11 on the Linux desktop? Quite a while seems likely."

An anonymous reader writes "Reiser4 still hasn't been merged into the mainline Linux kernel, but it's still being worked on by a small group of developers following Hans Reiser being convicted for murdering his wife. Reiser4 was updated in September on SourceForge to work with the Linux 3.5 kernel and has been benchmarked against EXT4, Btrfs, XFS, and ReiserFS. Reiser4 loses out in most of the Linux file-system performance tests, has much stigma due to Hans Reiser, and Btrfs is surpassing it feature-wise, so does it have any future in Linux ahead?"

An anonymous reader writes "The Mesa developers released Mesa 9.0 with open-source OpenGL 3.1 driver support. This de facto OpenGL Linux implementation now supports the several year old OpenGL 3.1 specification for Intel hardware while the other drivers are still at OpenGL 3.0 or worse. Other features to Mesa 9.0 include completing MPEG1/MPEG2 video acceleration, early OpenCL support, bug-fixes, and new hardware support." OpenGL 3.1 support is limited to Intel hardware, but at least ATI/AMD hardware supports some of OpenGL 3.1. A few features from OpenGL 4 were also added.
