Linux is a family of open-source Unix-like operating systems based on the Linux Kernel. It has several distributions that they call distro and also it has several flavours, which they call desktop-environment and window-manager.
Linux Distributions:
Here is a list of Linux distros that I have tried:
From all of these Linux distros, I loved using the Fedora distro, but also I enjoyed using EndeavourOS for the ease of installation, but also for the Arch wiki page that has an extensive info about Linux. Also, for Hyprland, I find that Arch Linux has more information about the installations, tutorials, troubleshooting, workarounds and guides.
