GPU acceleration All the needed AMD stuff is pretty well documented in the manual. I’m gaming on NixOS with even my “relatively old” AMD GPU.
nixgl The only time I heard about needing that was when using plain “nix” (not NixOS), as in using Nix under any other OS, to run graphic applications. I haven’t touched nixgl at all, and don’t see the need for it.
alacritty and kitty Literally my terminals (kitty is my main) + foot. Both working easily either under main NixOS config or Home-Manager. What’s supposed to not be working there?
Literally don’t know what your problems are/where they lie. I’m a Linux noob (don’t even have the patience for Arch Wiki + install), coming from Pop_OS to NixOS and I’m happy it’s all so easy.
I love NixOS! Been using it on all my devices since January and probably never going back :)
It all sinply just works™! Don’t worry about configuration :) As long as you’re not using relatively obscure software, you’ll be more than fine reading the docs/manual :)
If you still want to use obsure stuff though, the community on matrix is very active and helpful! Plus most (interesting) projects have at least one or two very dedicated Nix fanatics (/maintainers) willing to help others :D
bottom, if you know what I mean.
