    Linux on the Apple M1 takes another step closer with Ubuntu working thanks to Corellium

    news.movim.eu / GamingOnLinux · Yesterday - 19:54 · 1 minute

ARM virtualization company Corellium has managed to get Ubuntu Linux running on the next-generation Apple M1.

The news comes from Corellium CEO, Chris Wade, who mentioned on Twitter how "Linux is now completely usable on the Mac mini M1. Booting from USB a full Ubuntu desktop (rpi). Network works via a USB c dongle. Update includes support for USB, I2C, DART. We will push changes to our GitHub and a tutorial later today.".

Impressive speedy work, and a separate project to the recently revealed Asahi Linux which is also aiming to do the same thing. Two heads are better than one, as they say. The Corellium team mentioned on Twitter they full back the Asahi project too, so it's wonderful to see true cooperation.

Right now this effort doesn't appear to have full GPU acceleration so it's doing software rendering, making it less suitable for a daily driver but work is ongoing towards that. Eventually everything will be in place, and it's taking far less time than I personally expected to see it running on such brand new hardware from Apple.

Thing thing is, as we noted in our article about the Asahi project, even Linux creator Linus Torvalds previously said in 2020 "I'd absolutely love to have one, if it just ran Linux" when talking about the new Apple M1 laptops.

You can see the code from Corellium up on GitHub .

    Grab an up to date MangoHud with NVML, GOverlay and vkBasalt on Ubuntu with a new PPA

    news.movim.eu / GamingOnLinux · Monday, 14 December - 10:10 · 1 minute

Canonical (Ubuntu and Ubuntu MATE) developer Martin Wimpress has announced a fresh PPA for Linux gamers.

For users on Ubuntu-based distributions, PPAs are often needed for you to get the latest and greatest software since if you're not using Snaps or Flatpaks (and sometimes they don't work due to the containers), a lot of software is stuck in place until a newer version of Ubuntu.

What's the fuss here then? Well, Ubuntu and Ubuntu-based distribution users can now grab the excellent MangoHud gaming overlay, the vkBasalt Vulkan post processing layer and the GOverlay application for managing them both in a tidy UI all nicely up to date from this PPA . The build of MangoHud included also has NVML (NVIDIA Management Library) enabled, meaning out of the box it should allow showing GPU metrics from NVIDIA GPUs.

This was all enabled thanks to Debian Linux maintainer Stephan Lachnit , who has been sorting out the packages for Debian itself (which Ubuntu is based upon) and offered some tips to Wimpress on the packaging. Wimpress mentioned that the PPA will be kept up to date too.

Nice to see grabbing some really useful open source software made even easier for Ubuntu fans.

    OpenZFS 2.0 release unifies Linux, BSD and adds tons of new features

This Monday, ZFS on Linux lead developer Brian Behlendorf published the OpenZFS 2.0.0 release to Github. Along with quite a lot of new features, the announcement brings an end to the former distinction between "ZFS on Linux" and ZFS elsewhere (for example, on FreeBSD). This move has been a long time coming—the FreeBSD community laid out their side of the roadmap two years ago—but this is the release that makes it official.

Availability

The new OpenZFS 2.0.0 release is already available on FreeBSD, where it can be installed from ports (overriding the base system ZFS) on FreeBSD 12 systems, and will be the base FreeBSD version in the upcoming FreeBSD 13. On Linux, the situation is a bit more uncertain and depends largely on the Linux distro in play.

Users of Linux distributions which use DKMS-built OpenZFS kernel modules will tend to get the new release rather quickly. Users of the better-supported but slower-moving Ubuntu probably won't see OpenZFS 2.0.0 until Ubuntu 21.10, nearly a year from now. For Ubuntu users who are willing to live on the edge, the popular but third-party and individually-maintained jonathonf PPA might make it available considerably sooner.

    Ubuntu, Snap, les performances de chromium se dégradent

    pubsub.eckmul.net / linuxfr · Sunday, 15 November - 21:12 · 1 minute

<p>Bonjour à tous,</p> <p>J'ai passé quelques temps ce week end sur un soucis que je rencontre avec chromium depuis la mise à jour de la distribution de mon ordinateur portable sous KDE Neon vers la 20.04. La distribution est basée sur Ubuntu.</p> <p>Le soucis était lié à la consommation mémoire du navigateur, avec mon environnement de travail et seulement quelques onglets ouverts le système utilisait rapidement plus que les 8Go de RAM disponibles. </p> <p>Suspectant fortement le passage au format snap du package j'ai décidé de tenter l'installation du package natif de la Debian stable et je dois dire que cela change tout, je reste sous les 5Go d'occupation de la RAM avec le même environnement de travail et un navigateur avec de nombreux onglets ouverts.</p> <p>Donc si vous constatez une consommation mémoire particulièrement élevée après mise à jour d'une Ubuntu en utilisant chromium, vous pouvez creuser de ce coté, c'est loin d'être négligeable comme écart et on peut facilement passer d'un système performant à une machine qui swap pour ce "détail".</p> <p>La procédure utilisée : <a href="https://www.linuxtricks.fr/wiki/ubuntu-installer-chromium-de-debian-au-lieu-du-snap">https://www.linuxtricks.fr/wiki/ubuntu-installer-chromium-de-debian-au-lieu-du-snap</a></p> <div><a href="https://linuxfr.org/users/chrisk/journaux/ubuntu-snap-les-performances-de-chromium-se-degradent.epub">Télécharger ce contenu au format EPUB</a></div> <p> <strong>Commentaires :</strong> <a href="//linuxfr.org/nodes/122241/comments.atom">voir le flux Atom</a> <a href="https://linuxfr.org/users/chrisk/journaux/ubuntu-snap-les-performances-de-chromium-se-degradent#comments">ouvrir dans le navigateur</a> </p>

    Ubuntu fixes bugs that standard users could use to become root

Ubuntu developers have fixed a series of vulnerabilities that made it easy for standard users to gain coveted root privileges.

“This blog post is about an astonishingly straightforward way to escalate privileges on Ubuntu,” Kevin Backhouse, a researcher at GitHub, wrote in a post published on Tuesday . “With a few simple commands in the terminal, and a few mouse clicks, a standard user can create an administrator account for themselves.”

The first series of commands triggered a denial-of-service bug in a daemon called accountsservice, which as its name suggests, is used to manage user accounts on the computer. To do this, Backhouse created a Symlink that linked a file named .pam_environment to /dev/zero, changed the regional language setting, and sent accountsservice a SIGSTOP . With the help of a few extra commands, Backhouse was able to set a timer that gave him just enough time to log out of the account before accountsservice crashed.

    Raspberry Pi 400—the under-$100 desktop PC you didn’t know you needed

    news.movim.eu / ArsTechnica · Monday, 2 November - 22:01 · 1 minute

Late Friday afternoon, I got an exciting SMS notification—my review sample of the new Raspberry Pi 400 had arrived. I learned of the new Pi model last week while interviewing Raspberry Pi founder Eben Upton and Canonical desktop engineering director Martin Wimpress about Ubuntu 20.10's newly improved desktop support for the Pi hardware family.

In brief, the Pi 400 is a slightly faster version of the 4GiB Pi 4 which ships preassembled in a small, wedge-shaped chassis with integrated keyboard. The new model directly targets desktop replacement use and can be purchased solo for $70 or as a full kit (as seen above) for $100 .

The new form factor—which has apparently been in the works ever since the introduction of the official Raspberry Pi keyboard —addresses and enthusiastically supports the Pi 4's growing use case as a replacement or alternative for the traditional desktop PC. Upton told Ars that the Pi 400 is about 20 percent faster than the Pi 4; it has largely the same components under the hood but on a differently laid-out board, and its BCM2711 CPU is clocked a touch higher than the BCM2711 in the Pi 4.

    Ubuntu Groovy Gorilla adds Raspberry Pi as a “first class citizen”

Last week, Canonical released the latest intermediate version of Ubuntu, 20.10 "Groovy Gorilla"—which, for the first time, adds first-class platform support for the Raspberry Pi 4.

Groovy Gorilla itself is a pretty typical interim release, offering an updated GNOME version (3.38) with lots of bugfixes and small feature additions, such as drag-and-drop organization of folders and shortcuts in the Applications grid. Support has also been added for Windows Active Directory in the Ubiquity OS installer itself.

Canonical embraces the Pi

While it's been possible for some time to install Ubuntu on Raspberry Pi hardware, up until now that's been strictly a community effort. The Pi itself ships with Raspberry Pi OS , a Debian-based distribution whose origins began with the Pi community, but which has since been officially adopted and supported by the Raspberry Pi Foundation itself. And while Canonical added the Pi as a supported platform in 20.04 Focal Fossa earlier this year, that support was only for the Ubuntu Server distribution—not Desktop.
