I use EndeavourOS with Hyprland on my laptop but I am considering trying VanillaOS (once they move to Debian base). On desktop I have Ubuntu 20.04 and EndeavourOS (both on Gnome)

Maybe I'll write something in the future

I have a Microsoft Surface 7 running NixOS. Everything works, even touch/pen

It was not too hard if you are already familiar with Nix. The features supported (and the custom Linux kernel) can be found in surface-linux. For NixOS I used the nix-hardware flake to simplify things.

The worst part was the compilation of the Linux kernel, that took hours on the surface. Eventually, I used the remote nix build feature to compile on a more capable computer.
