After this week already seeing how the open-source graphics drivers supplied by Ubuntu 14.04 LTS allow Radeon Gallium3D to run at ~80% of the Catalyst Linux driver and how open-source graphics still struggle with older hardware, our latest testing of the Ubuntu 14.04 LTS development version that will be released next month leads us to benchmarking 30 different AMD Radeon and NVIDIA GeForce graphics cards under this popular desktop Linux distribution.

One of the long-standing proclaimed benefits of Direct Rendering Manager (DRM) graphics drivers for the Linux kernel was that it would be possible to have "Blue Screen of Death"-like error messages in cases of kernel issues. That feature is now closer to being realized while also advancing another goal of disabling VT support within the Linux kernel.
The X.Org Foundation Board of Directors is continuing to work on their possible merger with the SPI organization.
The TvHeadend project is a long-standing TV streaming server for Linux, but its main developer may be fading out after not finding many contributions and new user engagement from the community.
Upstream NetworkManager now has support for the Virtual Extensible LAN.
Enlightenment's Ecore library now has support for interfacing with the kernel's Direct Rendering Manager drivers.

Mozilla has introduced a new open-source JPEG encoding library that it claims can measurably reduce the file-size of encoded images.
The OpenELEC HTPC/multimedia Linux distribution is out today with their first beta release of the upcoming 4.0 series. OpenELEC 4.0 will bring many front-end and back-end changes to this distribution centered around XBMC.
Last month I wrote about Intel's Bay Trail NUC Kit on Linux and shared some early Intel Bay Trail Linux benchmarks. That earlier testing was done from Ubuntu 13.10 but this DN2820FYKH NUC can also be made to work quite well with Fedora 20. Here's the experience on setting up Fedora 20 for the Intel Bay Trail NUC Kit and some Ubuntu vs. Fedora benchmarks from this low-power, mini Intel system.
For users of the BFS scheduler patches to the kernel, they have been updated this week for the Linux 3.13 kernel.
Following the Krita 2.8 availability, the Calligra 2.8 open-source office suite is now available.
Fedora contributors from certain nations may face scrutiny by Fedora's legal department if they reveal their nationality, country of origin, or country of residence; the issue comes down to US export restrictions.
The Xephyr GLAMOR code and code that adds DRI3 support to GLAMOR has been called to be pushed into the xorg-server code-base for X.Org Server 1.16.
We have known for a while now that Fedora 21 won't be released before August, but it looks like the actual release that's now being planned won't happen until the fourth quarter.
The performance of several different Samsung laptop models will soon improve under Linux thanks to an important kernel fix that will appear in the Linux 3.15 kernel. This important patch addresses some ACPI issues and system performance issues for multiple Samsung laptops that have plagued Linux for at least two years.
Thanks to recent work on systemd's logind, it's now possible to install the X.Org Server binary without suid root rights while having everything work correctly, assuming you are using KMS drivers.
Last week we talked about Broadcom finally open-sourcing their VideoCore IV 3D Graphics Stack and it is indeed the real McCoy, but the $10,000 Quake III bounty has yet to be claimed for getting it to work on the Raspberry Pi.
Mesa 10.1 was released this morning as the latest three-month update to this 3D library and graphics driver stack used throughout the Linux desktop ecosystem. With Mesa 10.1 there are tons of improvements, while one of the big highlights is OpenGL 3.3 support for the open-source Radeon and Nouveau drivers.
The big Krita 2.8 release of this KDE oriented open-source digital painting program has been released.
AMD has launched the Radeon R9 280 graphics card, but don't get too excited just yet.
Yesterday on Phoronix I published results showing the Radeon Gallium3D performance getting close to Catalyst for the Radeon HD 5000 series and newer GPUs that are supported by the mainline Catalyst driver. On the open-source side the hardware is supported by the R600 and RadeonSI (for the GCN hardware) Gallium3D drivers. Yesterday's results showed that on Ubuntu 14.04 for many OpenGL workloads the R600/RadeonSI Gallium3D drivers were now ~80% the speed of the proprietary Catalyst driver in many instances. While this is a great feat, how does it stand for older generations of AMD Radeon hardware? In this article are Radeon HD 4870 benchmarks looking at the performance of the open-source AMD Linux driver over three years of Ubuntu Linux releases and compared to the legacy Catalyst driver from 2011.

Intel's Mesa DRI driver on Linux has picked up support for another OpenGL 4 extension, but for now at least the hardware support is limited to the yet-to-be-released Broadwell.

On the same day as announcing KDE Frameworks 5 Alpha 2 with improved Wayland support, the KDE development community has gone ahead and announced KDE 4.12.3 as their latest monthly point release.
Robert Carr at Canonical has ported Google's Chromium web-browser to Mir. The "Mir-Ozone" component allows Chromium to run natively on Mir, which in turn is based on Wayland code.
We've already seen some Radeon DRM graphics driver code queued up for merging into the Linux 3.15 kernel in a few weeks time. Arriving this morning were another batch of exciting Radeon changes that will target the Linux 3.15 merge window.

With the open-source graphics driver stack found in the forthcoming release of Ubuntu 14.04 LTS (Mesa 10.1 + Linux 3.13), the performance of the community-developed Radeon Gallium3D driver is now close to that of the official AMD Catalyst driver for recent generations of Radeon graphics cards. In several OpenGL tests the "RadeonSI" driver can even run 80% the speed of AMD's official Catalyst Linux driver.

In verifying and complementing the major R600/RadeonSI performance regressions noted earlier today for a wide-range of AMD Radeon hardware, here's some more tests that were done this weekend on a different system that also finds the newer code to be running slower than Linux 3.13 + Mesa 10.1
While Fedora 20 is looking to land GNOME 3.12 as a stable release upgrade, the developers normally shipping a bleeding-edge Linux graphics stack haven't sent down any stable release updates for the much-improved Mesa 10 drivers. Fortunately, there's some unofficial choices.
According to the latest figures published by Valve for their "Steam Hardware Survey", they put the percent of Linux gamers on Steam at 1.30%.
For anyone currently experiencing a slowdown of their Radeon Gallium3D open-source driver stack or are interested in helping out track down a new performance issue, it appears the Linux 3.14 + Mesa 10.2 configuration is regressing on Ubuntu 14.04 LTS in place of Linux 3.13 + Mesa 10.1.
