ExTiX is dubbed the “Ultimate Linux System,” and it’s been updated earlier today by developer Arne Exton to version 18.4, based on Canonical’s upcoming Ubuntu 18.04 LTS operating system. However, ExTiX is using the lightweight and modern LXQt 0.12.0 as default desktop environment instead of GNOME, and it’s powered by the latest Linux 4.16.2 kernel. Besides being based on the Ubuntu 18.04 LTS and Linux kernel 4.16.2, the ExTiX 18.4 Build 180419 release replaces the Google Chrome web browser with Mozilla Firefox, which can be used to watch Netflix movies and TV shows, as well as Ubuntu’s Ubiquity installer with the more versatile Calamares universal installer framework.
