What’s New in PorteuX 2.5 | Linux Kernel 6.18, Flatpak, COSMIC, Cinnamon 6.6 & Persistence

PorteuX 2.5 is here, and this release takes the live Linux experience to a whole new level.
In this video, we take a deep dive into what’s new in PorteuX 2.5, a fast, modular, Slackware-based live Linux distribution designed for portability, performance, and control. This complete walkthrough covers the new Flatpak support in PorteuX 2.5, making it easier than ever to install modern desktop applications while keeping the base system clean and lightweight. We also explore the latest desktop environments included in this release, including Cinnamon 6.6 for a familiar, polished workflow and COSMIC 1.0, a next-generation Linux desktop focused on efficiency and tiling workflows.

Under the hood, PorteuX 2.5 runs on the Linux 6.18 kernel, bringing improved hardware compatibility, better Wi-Fi and GPU support, and smoother performance on modern systems. Since PorteuX is based on Slackware, we also look at Slackware-style package management, classic init scripts, and PorteuX modules, showing how this distribution stays fast and transparent.

A major focus of this video is persistence in PorteuX. You’ll learn how to enable persistence on a live USB, how the save file works, and how PorteuX remembers installed software, system settings, passwords, and Flatpak applications across reboots. We also clearly explain default passwords in PorteuX live, including the root password (toor), and how authentication works for GUI tools and persistence scripts.
