ExTiX 17.4 appears to be the second distro based on Canonical’s latest Ubuntu 17.04 (Zesty Zapus) operating system, after Ultimate Edition 5.4. However, ExTiX 17.4, which is dubbed “The Ultimate Linux System,” is also based on the repositories of Debian GNU/Linux 8.7 “Jessie” and Debian GNU/Linux 9 “Stretch.” The biggest new feature of the ExTiX 17.4 looks to be the latest LXQt 0.11.1 desktop environment, which replaces the Unity 7 user interface of Ubuntu 17.04. The distro is now powered by kernel 4.10.0-19-exton, which is based on Linux kernel 4.10.8, and all pre-installed packages have been updated to their latest versions.
