Ubuntu
Ubuntu is a complete desktop Linux operating system, freely available with both community and professional support. The Ubuntu community is built on the ideas enshrined in the Ubuntu Manifesto: that software should be available free of charge, that software tools should be usable by people in their local language and despite any disabilities, and that people should have the freedom to customise and alter their software in whatever way they see fit.
HackerOS
HackerOS is a live Linux distribution based on Debian's "Testing" branch and designed for regular users, gamers and cybersecurity enthusiasts. Some of its features include an optimised XanMod Linux kernel for faster boot times and reduced resource usage, out-of-the-box support for NVIDIA graphics cards, and a collection of cybersecurity tools, such as enhanced firewalls and intrusion detection software.
