Real-time Ubuntu 24.04 LTS integrates the PREEMPT_RT patch on AMD64 and ARM64. As the de-facto Linux real-time implementation, PREEMPT_RT increases predictability by modifying the existing kernel code. With time-bound responses for mission-critical latency requirements, Real-time Ubuntu 24.04 LTS provides deterministic processing to the most demanding workloads across industries, from manufacturing and automotive to the critical infrastructure of telco operators.

If you need it, you need it, but it’s exclusive to Ubuntu Pro. Luckily Pro is free for personal use, so if you really need Ubuntu but with a real-time kernel – based on Linux 6.8 – there’s nothing stopping you.

An anonymous reader shared this report from the blog OMG Ubuntu: Ubuntu first switched to using Wayland as its default display server in 2017 before reverting the following year. It tried again in 2021 and has stuck with it since. But while Wayland is what most of us now log into after installing Ubuntu, anyone doing so on a PC or laptop with an NVIDIA graphics card present instead logs into an Xorg/X11 session. This is because NVIDIA's proprietary graphics drivers (which many, especially gamers, opt for to get the best performance, access to full hardware capabilities, etc) have not supported Wayland as well as as they could've. Past tense as, thankfully, things have changed in the past few years. NVIDIA's warmed up to Wayland (partly as it has no choice given that Wayland is now standard and a 'maybe one day' solution, and partly because it wants to: opportunities/benefits/security). With the NVIDIA + Wayland sitch' now in a better state than before — but not perfect — Canonical's engineers say they feel confident enough in the experience to make the Ubuntu Wayland session default for NVIDIA graphics card users in Ubuntu 24.10.

It wasn’t too long ago that new Ubuntu releases were major happenings in the Linux world, as it was the default Linux distribution for many, both old and newcomers, in the desktop Linux space. These days, Ubuntu release hit a little different, with Canonical’s focus having shifted much more to the enterprise, and several aspects of the distribution being decidedly unpopular, like the snap package management system.

Still, Ubuntu is probably still one of the most popular, if not the most popular, distributions out there, so any new release, like today’s Ubuntu 24.0 LTS, is still a big deal.

Ubuntu Desktop brings the Subiquity installer to an LTS for the first time. In addition to a refreshed user experience and a minimal install by default, the installer now includes experimental support for ZFS and TPM-based full disk encryption and the ability to import auto-install configurations. Post install, users will be greeted with the latest GNOME 46 alongside a new App Center and firmware-updater. Netplan is now the default for networking configuration and supports bidirectionality with NetworkManager.

Of course, all the various other Ubuntu editions have also seen new releases: Edubuntu, Kubuntu, Lubuntu, Ubuntu Budgie, Ubuntu Cinnamon, Ubuntu Kylin, Ubuntu MATE, Ubuntu Studio, Ubuntu Unity, and Xubuntu. Yes, that’s a long list. They all mostly share the same improvements as Ubuntu’s main course, but paired with the latest versions of the respective desktop environments instead.

Except for Kubuntu. Unlike just about any other major distribution released over the last few months, such as Fedora 40 only a few days ago, Kubuntu does not ship with the new KDE Plasma 6, opting for Plasma 5.27.11 instead. There simply wasn’t enough time between the release of Plasma 6 and the Ubuntu feature freeze, so they made the – in my opinion – understandable call to stick to Plasma 5 for now, moving Plasma 6 to the next release later this year.

So with Ubuntu 24.04 LTS is the ability to continue with a standard EXT4 file-system install, an encrypted file-system using LVM, or using OpenZFS with/without encryption. Ubuntu 24.04 LTS also has the ability to enjoy hardware-backed full-disk encryption with TPM as another new experimental option. Or, of course, the Ubuntu desktop installer continues supporting manual (custom) partitioning as well.

I just use whatever Btrfs setup Fedora automatically recommends when I let it take over a disk – file systems for desktops seems a bit like a solved problem to me personally – but I’m still curious what benefits, for instance, an OpenZFS setup could bring to a desktop user compared to Btrfs or a basic Ext4 setup. Why should a desktop user use OpenZFS?
