You are most definitely running Discord in XWayland. You need to add chromium flags to make it run in native Wayland. You also need to have an xdg desktop portal to support screen sharing.

If you want screenshare to work on an app that can't run in wayland, use XWaylandVideoBridge

Yea you can.

Should work fine. I really recommend installing the nix package manager on your current distro to play with the language and how it works, I did it on arch to get familiar and it has been really helpful.

Thanks, I’ll hope to not use docker though - planning to run NixOS, which has a module for it.

Just double checked, the nixpkgs for lemmy-ui and lemmy-server have aarch64-linux support B)

For me, NixOS is like someone took the archwiki and made a distro with it. I can just do

services.lemmy = {
  enable = true;
  settings = {
    hostname = "lemmy.union.rocks";
    database.createLocally = true;
  };
  caddy.enable = true;
}

in my system config (example from Nix manual). It will install lemmy, install caddy, start lemmy backend on port 8536, frontend on 1234, expose it with a caddy reverse proxy to that hostname, and initialize a postgres database. This is also reproducible across systems, so it's pretty much guaranteed to work the same on one PC and on another.

This is very useful, because some programs require some more configuration, and this can remove the need to know where to put their config files, their package names, systemd service names from your head. It's all in there.

Also, when I fuck something up... when changing the config, it makes a new boot entry with it, so when booting I can just press arrow down when booting to select an older, working config. Magic.

Packages are also nicely separated from each other. I don't have to install stuff globally, when I need a program one time I can just do nix shell nixpkgs#audacity and have an ephemeral shell with the package installed.

There are (optiona) binary caches, so you practically don't have to compile anything from source when updating your system.

I have all my configuration on GitHub, like a lot of people, which makes it easy to share information.

A con is that when a program hasn't been packaged for NixOS (whether it's in nixpkgs or has a flake.nix in the repo), it's not that easy to use it, so learning to write derivations (packages) for NixOS is pretty much a must have.

Also another must have is being in some community that uses NixOS, because it is really hard to learn without someone to help and guide you IMO.

Worth it though

I'm pretty sure the website is mostly directed at distro maintainers, to not force a custom theme on users. They're fine with users tinkering on their own.
