@fsf i have found the perfect distro for me. It's #NixOS with the #Pantheon desktop from @elementary.

This way i have a stable base system, can use packages from "unstable" easily and have state-of-the-art usability. The only proprietary parts i need are Steam (including games) and Nvidia driver.

You can replicate my system from this config.: https://github.com/davidak/nixos-config/blob/master/machines/gaming/configuration.nix

I don't have extra free time now, but i use my free time to improve #NixOS and other free software projects.
