Ubuntu 24.10 Will Use Wayland by Default with NVIDIA

The use of Wayland by default with the official NVIDIA driver has been a pending issue in Ubuntu since the change was reversed at the last minute in version 22.04 LTS of the distribution. However, it seems this will soon be rectified according to an update to the GDM3 package published on Launchpad.net by Daniel van Vugt, who is a Canonical employee, a GNOME contributor, and a key figure in the development of Ubuntu for the desktop.

Daniel van Vugt explains the following in the update to the GDM3 package that will be used by the upcoming Ubuntu 24.10: "Remove Ubuntu-specific rules that made Xorg the default for NVIDIA. The patch Revert-data-Disable-GDM-on-hybrid-graphics-laptops-with-v.patch has been updated to ensure that NVIDIA 5xx drivers always default to Wayland unless there is a stronger reason why it won't work (such as modeset being disabled in the kernel command line). Also update the patch description with a more recent justification."

In recent months, NVIDIA has made significant strides in improving its support for Wayland. Notably, explicit synchronization, which is already active in version 555 beta of the official driver from the green giant. In technical terms, explicit synchronization promises to enhance graphics performance by reducing the workload the driver has to handle. For users, especially those using NVIDIA, this should translate into a reduction in flickering and other graphical issues that are still present.

In other words, NVIDIA is now supposed to have all the necessary foundations to finally offer a Wayland experience on par with what Intel and AMD have been able to provide, as they have had a significant advantage by adopting the system's standard graphics stack. Adding to this, Ubuntu 24.10 is in an ideal position since it is the first version with nine months of support following the release of the latest LTS, giving Canonical a year and a half to refine and improve the experience from their side. The NVIDIA driver remains exclusively under the control of the green giant, given that it is largely proprietary.

Based on the information in the Launchpad post, Ubuntu 24.10 should use Wayland by default with the 5XX version of the official NVIDIA driver. However, this implies that with the company’s semi-legacy drivers, which are geared towards older GPU models, Xorg will continue to be used by default. For older NVIDIA graphics cards, it might be worth giving Nouveau a chance, especially if the semi-legacy driver does not deliver the desired performance.

Although the GDM3 package still references GNOME 46, it is assumed that Ubuntu 24.10 will use GNOME 47, and therefore the graphical session manager should correspond to this latest version. This change, which we assume will be maintained given the nature of the upcoming release of the distribution, represents another small step toward the definitive consolidation of Wayland.

systemd 256 arrives with run0, the ‘sudo clone’ that aims to improve security

systemd 256 arrives with run0, the ‘sudo clone’ that aims to improve security systemd 256 is now a reality, featuring an interesting innovation that could represent a significant change in Linux in the not-too-distant future, although this will ultimately depend on the decisions made by various distributions. Without further delay, let’s go over the main new features. First, we have the introduction of run0, a kind of clone of sudo that aims to enhance security by reducing the attack surface. According to Lennart Poettering, the creator of systemd, this is achieved by ensuring “the target command is invoked in an isolated execution context, freshly forked from PID 1, without inheriting any context from the client,” making its behavior more akin to SSH. And since we’ve mentioned SSH, there’s the systemd-ssh-generator , which has been added to detect if the SSHD binary (the SSH daemon) is present and then link it through socket activation per connection to various sockets depending on

Kubernetes 1.30 Available, New Version of the Container Orchestrator

Kubernetes 1.30, named “Uwurnetes,” has been released as the new stable version of the well-known container orchestrator, which originated at Google and is now under the umbrella of The Linux Foundation. The developers have described this release as "the most beautiful" in the history of the software and have announced it includes a total of 45 new features, with 17 in stable phase, 18 in beta, and 10 in alpha. However, here we will only mention the most important ones. The first notable update in Kubernetes 1.30 is the stable release of the Robust VolumeManager rebuild after restarting the kubelet. This involves a refactoring of the volume manager that allows the kubelet to complete additional information on how existing volumes are mounted during the kubelet's startup. Generally, this makes volume cleanup more robust after restarting the kubelet or the machine. Also arriving in stable phase is the prevention of unauthorized volume mode conversion during volume restora

Fedora Asahi Remix 40, the new version of Linux for Apple Silicon

  Fedora Asahi Remix 40 has been announced as the latest version of the Fedora-based system designed to run on Mac computers with Apple Silicon processors. This version primarily represents an evolution of what was already present, which is quite significant given the project's potential to enhance the Linux desktop experience, particularly in areas like sound. According to Fedora Magazine, Fedora Asahi Remix is developed through close collaboration between the Asahi Linux team and the Fedora Asahi Special Interest Group (SIG). It's worth noting that Asahi Linux is not a traditional distribution but rather a technology platform that enables running Linux on Apple Silicon processors. However, this doesn't stop its Fedora remix from being a reference system. As expected, Fedora Asahi Remix 40 is based on Fedora 40 and uses KDE Plasma 6 as its desktop environment. Therefore, the Wayland session should be the default, especially given the strong support this system has for th
