This week System76 launched the first stable release of its Rust-based COSMIC desktop environment, reports 9to5Linux.
Announced in 2021, it's designed for all GNU/Linux distributions — and it shipping with Pop!_OS 24.04 LTS (based on Ubuntu 24.04 LTS):
Previous Pop!_OS releases used a version of the COSMIC desktop that was based on the GNOME desktop environment. However, System76 wanted to create a new desktop environment from scratch while keeping the same familiar interface and user experience built for efficiency and fun. This means that some GNOME apps have been replaced by COSMIC apps, including COSMIC Files instead of Nautilus (Files), COSMIC Terminal instead of GNOME Terminal, COSMIC Text Editor instead of GNOME Text Editor, and COSMIC Media Player instead of Totem (Video Player).
Also, the Pop!_Shop graphical package manager used in previous Pop!_OS releases has now been replaced by a new app called COSMIC Store.
"If you're ambitious enough, or maybe just crazy enough, there eventually comes a time when you realize you've reached the limits of current potential, and must create something completely new if you're to go further..." explains System76 founder/CEO Carl Richell:
For twenty years we have shipped Linux computers. For seven years we've built the Pop!_OS Linux distribution. Three years ago it became clear we had reached the limit of our current potential and had to create something new. Today, we break through that limit with the release of Pop!_OS 24.04 LTS with the COSMIC Desktop Environment.
Today is special not only in that it's the culmination of over three years of work, but even more so in that System76 has built a complete desktop environment for the open source community...
I hope you love what we've built for you. Now go out there and create. Push the limits, make incredible things, and have fun doing it!

Steven J. Vaughan-Nichols files this report from Tokyo:
At the invitation-only Linux
Kernel Maintainers Summit here, the top Linux maintainers decided, as Jonathan Corbet, Linux kernel developer, put it, "The consensus among the assembled developers is that Rust
in the kernel is no longer experimental — it is now a core part
of the kernel and is here to stay. So the 'experimental' tag
will be coming off." As Linux kernel maintainer Steven Rosted told
me, "There was zero pushback."
This has been a long time coming. This shift caps five years of sometimes-fierce debate over whether the memory-safe language belonged alongside C at the heart of the world's most widely deployed open source operating system... It all began when Alex Gaynor and Geoffrey Thomas at the 2019 Linux Security Summit said that about two-thirds of Linux kernel vulnerabilities come from memory safety issues. Rust, in theory, could avoid these by using Rust's inherently safer application programming interfaces (API)... In those early days, the plan was not to rewrite Linux in Rust; it still isn't, but to adopt it selectively where it can provide the most security benefit without destabilizing mature C code. In short, new drivers, subsystems, and helper libraries would be the first targets...
Despite the fuss, more and more programs were ported to Rust. By April 2025, the Linux kernel contained about 34 million lines of C code, with only 25 thousand lines written in Rust. At the same time, more and more drivers and higher-level utilities were being written in Rust. For instance, the Debian Linux distro developers announced that going forward, Rust would be a required dependency in its foundational Advanced Package Tool (APT).
This change doesn't mean everyone will need to use Rust. C is not going anywhere. Still, as several maintainers told me, they expect to see many more drivers being written in Rust. In particular, Rust looks especially attractive for "leaf" drivers (network, storage, NVMe, etc.), where the Rust-for-Linux bindings expose safe wrappers over kernel C APIs. Nevertheless, for would-be kernel and systems programmers, Rust's new status in Linux hints at a career path that blends deep understanding of C with fluency in Rust's safety guarantees. This combination may define the next generation of low-level development work.

New submitter emangwiro shares a report: The HDMI Forum, responsible for the HDMI specification, continues to stonewall open source. Valve's Steam Machine theoretically supports HDMI 2.1, but the mini-PC is software-limited to HDMI 2.0. As a result, more than 60 frames per second at 4K resolution are only possible with limitations. In a statement to Ars Technica, a Valve spokesperson confirmed that HDMI 2.1 support is "still a work-in-progress on the software side." "We've been working on trying to unblock things there."
The Steam Machine uses an AMD Ryzen APU with a Radeon graphics unit. Valve strictly adheres to open-source drivers, but the HDMI Forum is unwilling to disclose the 2.1 specification. According to Valve, they have validated the HDMI 2.1 hardware under Windows to ensure basic functionality.

Jolla is "trying again with a new crowd-funded smartphone," reports Phoronix:
Finnish company Jolla started out 14 years ago where Nokia left off with MeeGo and developed Sailfish OS as a new Linux smartphone platform. Jolla released their first smartphone in 2013 after crowdfunding but ultimately the Sailfish OS focus the past number of years now has been offering their software stack for use on other smartphone devices [including some Sony Xperia smartphones and OnePlus/Samsung/ Google/ Xiaomi devices].
This new Jolla Phone's pre-order voucher page says the phone will only produced if 2,000 units are ordered before January 4. (But in just a few days they've already received 1,721 pre-orders — all discounted to 499€ from a normal price between 599 and 699 €). Estimate delivery is the first half of 2026. "The new Jolla Phone is powered by a high-performing Mediatek 5G SoC," reports 9to5Linux, "and features 12GB RAM, 256GB storage that can be expanded to up to 2TB with a microSDXC card, a 6.36-inch FullHD AMOLED display with ~390ppi, 20:9 aspect ratio, and Gorilla Glass, and a user-replaceable 5,500mAh battery." The Linux phone also features 4G/5G support with dual nano-SIM and a global roaming modem configuration, Wi-Fi 6 wireless, Bluetooth 5.4, NFC, 50MP Wide and 13MP Ultrawide main cameras, front front-facing wide-lens selfie camera, fingerprint reader on the power key, a user-changeable back cover, and an RGB indication LED. On top of that, the new Jolla Phone promises a user-configurable physical Privacy Switch that lets you turn off the microphone, Bluetooth, Android apps, or whatever you wish.
The device will be available in three colors, including Snow White, Kaamos Black, and The Orange. All the specs of the new Jolla Phone were voted on by Sailfish OS community members over the past few months. Honouring the original Jolla Phone form factor and design, the new model ships with Sailfish OS (with support for Android apps), a Linux-based European alternative to dominating mobile operating systems that promises a minimum of 5 years of support, no tracking, no calling home, and no hidden analytics...
The device will be manufactured and sold in Europe, but Jolla says that it will design the cellular band configuration to enable global travelling as much as possible, including e.g. roaming in the U.S. carrier networks. The initial sales markets are the EU, the UK, Switzerland, and Norway.

Steam's November 2025 survey shows Linux gaming climbed to its highest share in a decade "thanks to the success of the Steam Deck, the underlying Steam Play (Proton) software, and now further excitement thanks to the upcoming Steam Machine and Steam Frame," writes Phoronix's Michael Larabel. From the report: A decade ago in the early Steam days the initial use was around 3% and back then the Steam user-base in absolute terms was much smaller than it is today. Back in October Steam on Linux finally re-crossed that 3% threshold after for years being stuck in a 1~2% rut. Now the Steam Survey results were published minutes ago for November and they continue an upward trend for Linux.
Steam on Linux is up to 3.2%, an increase of 0.15% for the month. One year ago Steam on Linux was at 2.03% last November, 1.91% for November 2023, and a decade ago for November 2015 was at just 0.98%. [...] Due to AMD APUs powering the Steam Deck, AMD CPUs continue to power nearly 70% of Linux gaming systems. Meanwhile under Windows, AMD has around a 42% CPU marketshare.
