I have been trying some of the immutable linux OSes because from what I understand they are more modern and feature better security and reliability. What I have found so far is shocking. Half of these don’t support my laptop (probably because it’s nvidia optimus). Some I tried like guix were very difficult to install, configure, and use with sprase documentation. Good luck trying to use KDE, wayland, or pipewire for example. BlendOS was notably better and could at least run on my laptop but chocked with nvidia driver issues.
I have switched to pop os on my laptop for now but looking at alternatives and what to install on my desktop.
Use the “Kinoite-main-Nvidia”-image from universal-blue.org. Sounds exactly like what you’re looking for, since you mentioned KDE, Pipewire, Wayland, and so on.
This is actually the route I decided to go at least for one of my machines. I don’t exactly know how to mark posts as solved. I have had some issues with my servarr setup which was based on docker compose as ublue seems allergic to docker-ce and podman isn’t compatible with my setup. I am having issues getting it to use things mounted from the host.
Edit: I managed to get the docker repo installed and my servarr setup up and running. It took some effort but it does work.
