Back in March Steam on Linux skyrocketed to 5.33% with more than double the Steam gaming marketshare of macOS. Then for April Steam on Linux pulled back to a still-great 4.52%, well above the times when Steam on Linux was at 2% or less for many years. Now the May 2026 figures have been published overnight by Valve.

The libinput input handling library used by both X.Org and Wayland environments on modern Linux desktops is out with a new security fix release. A new vulnerability is now public allowing for arbitrary root code execution.

Following thr 3mdeb consulting firm's recent release of their Dasharo build of Coreboot and AMD openSIL for the Gigabyte MZ33-ARI1 EPYC 9005 series motherboard, the same engineers continue working on their port of Coreboot and the openSIL CPU silicon initialization library to a Ryzen 9000 series consumer motherboard.

COSMIC Epoch 1.0.15 was released today and while it doesn't yet contain the new "Frosted Glass" option for the desktop UI, COSMIC Epoch 1.0.15 does contain some other notable enhancements.

After announcing the AMD EPYC 8005 "Sorano" series back in February, AMD recently began shipping these Zen 5 successors to the EPYC 8004 "Siena" line-up. With the EPYC 8005 product stack ranging from 8 to 84 cores and being drop-in upgrades for EPYC 8004 servers after a BIOS update, these are quite some interesting processors for those after a single socket, performant server. Up today are benchmarks of the EPYC 8635P as the flagship 84 core Sorano CPU.

Along with some GCC compiler tuning for Nova Lake and Diamond Rapids to deal with some new APX capabilities not proving beneficial for performance, new patch activity today is preparing GCC for function multi-versioning (FMV) for the AVX10.2 and APX instruction set extensions.

As noted back in April, with Ubuntu 26.04 LTS it's now possible to simply "apt install rocm" on Ubuntu Linux for installing AMD's open-source GPU compute stack. But as prominently noted there, what's shipped right now in Ubuntu 26.04 LTS is already months out of date compared to upstream ROCm. Fortunately, Canonical shared today that moving forward they plan to ship newer ROCm versions as stable release updates (SRUs).

While the upstream, open-source Nouveau driver already supports NVIDIA's Hopper and Blackwell graphics processors with the GPU System Processor (GSP) code path, the bring-up of the Rust-written Nova driver remains ongoing. Out this week is the 12th iteration of the Hopper and Blackwell enablement for this future open-source NVIDIA Linux driver.

Intel this week rolled out new versions of their open-source XPU Manager and Linux NPU driver software.

As a follow-up to the article last week about KRAID as a new compiler for modern Arm Mali graphics, that initial code has now been merged to Mesa 26.2 for benefiting the Panfrost and PanVK open-source drivers.

As another interesting takeaway from this week's Microsoft Build 2026 conference beyond their open-source Intelligent Terminal project is Coreutils for Windows. Microsoft is maintaining a fork of Rust Coreutils for Windows to ease the developer experience across Windows / WSL / macOS / Linux.

At the beginning of the year Canonical announced a Steam Snap package for Ubuntu ARM64 that leverages the FEX emulator for running x86/x86_64 games on ARM64. After months of testing and improvements, they now consider their Steam Snap for ARM64 to be stable.

Marek Olšák who had been a longtime AMD Linux driver engineer specializing in the RadeonSI Gallium3D driver, recently began working for Valve on their Linux graphics driver team. His focus has understandably shifted to working on the RADV Vulkan driver and one of his early optimizations now with the Valve hat on is up to a 100% pixel throughput optimization for the RADV driver, which is already quite well optimized thanks to years of investment from Valve, Red Hat, and others.

Microsoft today announced their newest open-source creation... Under the MIT license it's the Intelligent Terminal.

CachyOS ships with a good Linux kernel configuration by default balancing the different features as well as performance. But they also ship a variety of other kernel builds for those preferring a more leading-edge kernel or the current LTS series, a hardened kernel configuration, and more. In this article are some fresh benchmarks of the Arch Linux based CachyOS Linux distribution with some of its main kernel flavors.

KDE developers are sticking to their plans for Plasma 6.8 going Wayland-exclusive in dropping X11 support. Meanwhile it turns out 95% of current Plasma 6.6 users are running already on Wayland.

Now that the Linux kernel has been removing Intel 486 CPU support and also proceeding to drop other vintage CPUs like the AMD K5 CPU support and AMD Elan, the Linux kernel is ready to make the TSC support unconditional for x86 processors.

Mesa's NVK open-source NVIDIA Vulkan driver now has mesh shader support as another significant step forward for this driver in being able to handle modern Linux gaming and other workloads.

Canonical today released Mir 2.27 as the latest version of this set of compositor libraries for easily building Wayland-based shells on Linux and fitting into the Ubuntu Linux paradigm.

ASUS ZenVision is a feature of some ASUS laptops like the Zenbook 14X OLED Space Edition where there is a 3.5-inch monochrome screen embedded into the top lid of the laptop. From this mini display embedded into the top lid of the laptop it's possible to display animated themes, show the current date/time, battery status, or customized messages and the like. The practicality is rather limited as primarily it's for showing off to people around you besides when your laptop lid is closed, but now with experimental code it's now possible to use ZenVision on Linux.
