It might have. I've tried nixos on a mini PC meant as a home server, so most configuration is done via SSH and users don't change (much), I might have accidently activate it while trying nixos out.
Making users unable to login is a bit of an odd (side?) Effect, but maybe I'm not understanding the purpose of this option correctly. I'll stay away from it for now :D
Thank you everyone for all your suggestions! I'll quickly try to summarize them for myself. So what you suggest is:
Operating Systems:
Tiling Window Manager:
Recomended to use something based on wayland.
Status Bar:
Package Managers:
Packages:
At the moment I am trying to avoid anything where RedHat is involved. Not because of the recent controversy, but simply IBM is known to kill their software solutions on a whim. (although i still use ansible), so Fedora is unfortunately out (again, no judging on how great it is). I've been quite interested in EndevourOS, so that might be fun to try out. Debian for the desktop probably not right now. I'm running it on servers for stability, but for a desktop environment, i prefer having more recent packages (e.g. neovim). The "sales pitch" for Mint sounded pretty interesting as well. However i'll give NixOs a try first, simply because it was mentioned very often, same with sway.
Based on this i'll try out these combinations first:
If this does not satisfy, i'll look into endevourOS and mint, but that might require some Ansible I assume.
Thank you very much!
