Whether you’re a seasoned Linux user or a newcomer looking for a hassle-free experience, HeliumOS 10 has something to offer.
Why Choose HeliumOS 10? The Big Picture
Before we get into the nitty-gritty, let’s talk about why HeliumOS 10 stands out in the crowded world of Linux distributions. Here are the key reasons it’s worth your attention:
- 10 Years of Support: Unlike some distros with short lifecycles (looking at you, Fedora, with your 13-month support!), HeliumOS 10 promises a decade of updates and support. This makes it ideal for users who want a stable, long-term platform without constant reinstalls or upgrades.
- Immutable and Atomic Design: HeliumOS uses bootc (bootable containers) and rpm-ostree to deliver atomic updates. This means updates are applied as a single, cohesive unit, reducing the risk of system instability. If an update fails, you can roll back without breaking a sweat.
- KDE Plasma Desktop: HeliumOS 10 has switched from GNOME (used in earlier versions) to KDE Plasma 6.4.2, offering a modern, customizable, and feature-rich desktop environment that’s perfect for both power users and beginners.
- Out-of-the-Box NVIDIA Support: No more wrestling with driver installations! HeliumOS 10 includes support for NVIDIA GPUs right from the start, using NVIDIA’s open-source GPU Kernel Modules.
- Security First: With default support for Secure Boot and optional LUKS full-disk encryption, HeliumOS 10 prioritizes your data’s safety.
- Containerization Ready: HeliumOS comes with Docker and Distrobox preinstalled, making it a dream for developers who work with containers.
Now, let’s break down these features and more to see what makes HeliumOS 10 tick.
Core Features of HeliumOS 10
1. Built on AlmaLinux 10 for Rock-Solid Stability
HeliumOS 10 is based on AlmaLinux 10, a community-driven enterprise Linux distribution that’s a spiritual successor to CentOS. AlmaLinux is known for its stability and long-term support, making it an excellent foundation for HeliumOS. The developers have worked closely with the AlmaLinux community, contributing to bootc images and ensuring a reliable base for HeliumOS 10.
This connection to AlmaLinux means HeliumOS inherits a Long-Term Support (LTS) Linux kernel (version 6.12), which prioritizes reliability over bleeding-edge updates. For users who need cutting-edge hardware support, there’s an experimental Edge Edition with Linux kernel 6.14, provided by the CentOS Hyperscale SIG. This dual approach lets you choose between stability and newer hardware compatibility, depending on your needs.
2. Atomic Updates with Bootc
One of the standout features of HeliumOS 10 is its use of bootc, a tool for creating bootable container images. Unlike traditional Linux distros that update individual packages, HeliumOS treats the entire system as a single, atomic unit. Updates are applied holistically, ensuring your system is always in a consistent state. If something goes wrong, you can roll back to the previous state with ease.
This atomic approach is a game-changer for reliability. As the developers note, “Your system will never get stuck in a ‘broken’ state.” For anyone who’s ever dealt with a botched update, this is music to the ears.
3. KDE Plasma 6.4.2: A Modern Desktop Experience
HeliumOS 10 has made a bold move by switching from GNOME to KDE Plasma 6.4.2 as its default desktop environment. This decision was driven by stability and feature considerations. Unlike GNOME, which relies on third-party extensions for basic features like system tray icons, KDE Plasma offers first-party support for a polished, customizable desktop experience.
KDE Plasma 6.4.2 brings a sleek, modern interface with plenty of customization options. Whether you want to tweak the look of your desktop or optimize your workflow, Plasma has you covered. Plus, HeliumOS pulls its Plasma packages from the EPEL (Extra Packages for Enterprise Linux) repository, ensuring they stay in sync with Fedora’s updates, so you’ll get the latest Plasma features over time.
4. NVIDIA GPU Support Out of the Box
For gamers and professionals using NVIDIA graphics cards, HeliumOS 10 is a breath of fresh air. The distro includes out-of-the-box support for NVIDIA GPUs using NVIDIA’s Open GPU Kernel Modules. This eliminates the headache of manually configuring drivers, a common pain point for Linux users. The developers have also fixed a stuttering issue with NVIDIA GPUs in the stable release, ensuring smooth performance for graphics-intensive tasks.
Note that while CUDA drivers aren’t included (due to legal restrictions), the open-source kernel modules provide robust support for most use cases. If you run into issues, the HeliumOS team encourages users to report them via the Bug Tracker.
5. Security Features: Secure Boot and LUKS Encryption
Security is a top priority for HeliumOS 10. The distro supports Secure Boot by default, using Microsoft-signed AlmaLinux Secure Boot Certificates. While you may need to disable Secure Boot during installation, you can re-enable it afterward for enhanced protection. For users with older BIOS or expired keys, importing AlmaLinux certificates is a straightforward fix.
Additionally, HeliumOS 10 uses BTRFS as its default filesystem, with an option for LUKS full-disk encryption during installation. This ensures your data is protected, whether you’re a casual user or someone handling sensitive information.
6. Developer-Friendly with Docker and Distrobox
HeliumOS 10 comes with Docker and Distrobox preinstalled, making it a great choice for developers working with containers. Docker Engine, Docker Compose, and the Docker CLI are all included, alongside Podman for Podman-incompatible use cases. For those who prefer a lightweight container solution, Distrobox allows you to spin up Podman containers with ease.
The distro also offers one-command installation scripts for tools like Rancher Desktop, simplifying the setup of development environments. For example, running heliumos-rancher_desktop-enable installs Rancher Desktop, while heliumos-rancher_desktop-disable removes it just as easily.
7. Zsh as the Default Shell
HeliumOS 10 swaps out Bash for Zsh as the default shell, complete with a polished and minimal configuration. Zsh is known for its powerful features, like advanced tab completion and customizable prompts, making it a favorite among developers and power users. This choice reflects HeliumOS’s focus on providing a modern, efficient user experience.
8. Expanded KDE Applications
The HeliumOS team has added several KDE utilities to enhance the user experience, including:
- KolourPaint: A simple paint program for quick edits.
- Okular: A versatile document viewer.
- KCalc: A scientific calculator for number crunching.
While some KDE applications, like the Discover store and Spectacle screenshot tool, are still in progress due to ongoing EPEL packaging, the team is working to include them in future updates.
