  • NVIDIA 390.59 Linux Driver Brings New GPU Support, X.Org Server 1.20 Compatibility

    For those using the long-lived NVIDIA 390 driver series rather than the latest NVIDIA 396 short-lived series (or happen to be stuck on 390 like for Fermi GPU support), the NVIDIA 390.59 Linux driver was released minutes ago.

    Most notable for existing NVIDIA 390 driver series is there is now xorg-server 1.20 compatibility. There is X.Org Server 1.20 support on the NVIDIA 396 series already, but for those using this long-lived driver branch, there is back-ported 1.20 server compatibility.

  • AMDGPU Feature Updates Submitted For Linux 4.18, Bringing Vega M & More

    Alex Deucher of AMD today submitted the initial batch of Radeon/AMDGPU DRM driver feature updates to DRM-Next that in turn are slated to land in the Linux 4.18 merge window in June. There's a fair amount of notable feature work this round for Radeon Linux users.

  • AMD Publishes Open-Source Driver Support For Vega 20

    AMD today published their big set of patches bringing open-source Linux kernel support for the "Vega 20" graphics processor.

    Vega 20 is the rumored 7nm AMD graphics processor that is said to be up to 70% faster than the current leading RX Vega 64 graphics card, according to some reported leaks. Vega 20 is expected to offer up to 32GB of HBM2 memory and be announced this calendar year, but there is some belief that it might just be a deep learning accelerator and not focused as a gaming graphics card or at least not initially.

  • Gallium3D's HUD Gets A Frametime Graph Capability

    In addition to being able to plot the frames per second, CPU usage, and many other possible sensor outputs, the Gallium3D Heads-Up Display (HUD) is now capable of showing the frametime while gaming.

  • Mesa 18.0.4 Coming This Week With More Fixes

    While Mesa 18.1 is expected for release this week, those riding the Mesa 18.0 stable series will also have an 18.0.4 point release coming in the next few days.

    Mesa 18.0.4 is expected for release this Thursday or Friday as the newest point release for this Q1'2018 Mesa series. Mesa 18.0.4 release candidate 1 was issued today with just over two dozen fixes.

  • Mesa 18.0.4 Linux Graphics Stack to Squash Rendering Bugs in Trine & The Witcher

    The Mesa graphics stack for Linux-based operating systems will soon receive a new maintenance update that addresses a few important bugs in some games and improves various of the included open-source graphics drivers.

    Mesa 18.0.4 is expected to arrive this week as the fourth maintenance update to the Mesa 18 series, bringing improvements to the r600 graphics driver for ATI/Radeon GPUs that fix some rendering bugs in the Trine and The Witcher video games, as well as several bug fixes for the Radeon RADV Vulkan driver.

    The Intel ANV Vulkan and Intel i965 OpenGL graphics drivers have been improved as well in this Mesa 18.0.4, which patches a leak in Intel's BLORP code for 4th Generation and 5th Generation Intel Core processors, and adds a few fixes to code emission around 16-bit integers and Image Signal Processor (ISP).

Graphics: XWayland and Mesa

  • XWayland Gets Patches For Better EGLStreams Handling
    While the recently released X.Org Server 1.20 has initial support for XWayland with EGLStreams so X11 applications/games on Wayland can still benefit from hardware acceleration, in its current state it doesn't integrate too well with Wayland desktop compositors wishing to support it. That's changing with a new patch series.
  • Intel Mesa Driver Finally Supports Threaded OpenGL
    Based off the Gallium3D "mesa_glthread" work for threaded OpenGL that can provide a measurable win in some scenarios, the Intel i965 Mesa driver has implemented this support now too. Following the work squared away last year led in the RadeonSI driver, the Intel i965 OpenGL driver supports threaded OpenGL when the mesa_glthread=true environment variable is set.
  • Geometry & Tessellation Shaders For Mesa's OpenGL Compatibility Context
    With the recent Mesa 18.1 release there is OpenGL 3.1 support with the ARB_compatibility context for the key Gallium3D drivers, but Marek Olšák at AMD continues working on extending that functionality under the OpenGL compatibility context mode.
  • Mesa Begins Its Transition To Gitlab
    Following the news from earlier this month that FreeDesktop.org would move its infrastructure to Gitlab, the Mesa3D project has begun the process of adopting this Git-centered software.

Welcome to Ubuntu 18.04: Make yourself at GNOME. Cup of data-slurping dispute, anyone?

Comment Ubuntu 18.04, launched last month, included a new Welcome application that runs the first time you boot into your new install. The Welcome app does several things, including offering to opt you out of Canonical's new data collection tool. The tool also provides a quick overview of the new GNOME interface, and offers to set up Livepatch (for kernel patching without a reboot). In my review I called the opt-out a ham-fisted decision, but did note that if Canonical wanted to actually gather data, opt-out was probably the best choice. Read more

How CERN Is Using Linux and Open Source

CERN really needs no introduction. Among other things, the European Organization for Nuclear Research created the World Wide Web and the Large Hadron Collider (LHC), the world’s largest particle accelerator, which was used in discovery of the Higgs boson. Tim Bell, who is responsible for the organization’s IT Operating Systems and Infrastructure group, says the goal of his team is “to provide the compute facility for 13,000 physicists around the world to analyze those collisions, understand what the universe is made of and how it works.” Read more
