Six months after the previous 25.05 “Warbler” release, the new stable version, NixOS 25.05 “Xantusia,” is officially here. Targeted at advanced users and developers, NixOS bets on an immutable design and an atomic update model, emphasizing reproducibility and reliability with the Nix package manager.

Nixpkgs adds 7,002 new packages and updates 25,252 existing entries. A cleanup effort removed 6,338 outdated packages to keep the repository manageable and secure. On the NixOS side, the release introduces 107 new modules, adds 1,778 configuration options, and removes older, unused components.

The desktop stack is updated to GNOME 49. This version ends X11 session availability, includes a new video player and document viewer, and ships a redesigned calendar application. Other applications across the GNOME suite receive updates as part of the regular upstream cycle.

How does NixOS ship with anything? It's all about what you put in the configuration.nix. You even have to specify if you want a WM.

    NixOS "ships with" whatever exists in nixpkgs. So you could read this as "nixpkgs channel 25.11 ships GNOME 49".

    And you can see that is true, here: https://search.nixos.org/packages?channel=25.11&show=gnome-shell&query=gnome-shell

    But it's worth noting that as with regular Linux distro, you can get easily switch the DE. I think it's only two lines of config.

    And unlike a regular Linux distro, you’ll have zero leftover systemd units or config files floating around in your FHS dirs. (You’ll have the binaries for Gnome sitting in /nix/store until you do a GC, so you can still quickly switch back if you want to.)

    .. or config files floating around in your FHS dirs

    Mostly true, but unless you're doing an impermanence setup, programs still poop random files all over the place. Especially in home and other various places like /var/lib /var/cache.

    switch

    I don't think there is even a default DE. I think the graphical installer lets you choose GNOME, Plasma, or none.

    Don't recall but you're probably right.

    Want Gnome? services.displayManager.gdm.enable = true; services.desktopManager.gnome.enable = true;

    Want KDE? services.displayManager.sddm.enable = true; services.displayManager.sddm.wayland.enable = true; services.desktopManager.plasma6.enable = true;

    As others have commented, the article is a little misleading. Especially to those not familiar with NixOS:

    • "The desktop stack is updated to GNOME 49."
    • "Under the hood, the release updates the Linux kernel to 6.17 (with 6.12 LTS also available)."

    These changes have been made available through packages in the nixpkgs repo, branched to the 25.11 release.

    However, NixOS doesn't "stack" GNOME into it. Nor does it carry specific Linux kernels "under the hood".

    You can pin any version of any release of any listed package (including kernels) from the nixpkgs repo to your configuration. More specifically even with Flakes, but that's not even required, if that isn't your thing.

    So for example, I am running a specific host with NixOS 25.11, and Linux kernel 6.17.58 (LTS). (There is a specific use case for me to do so on that particular host.) This runs out of the box due to how I've configured NixOS, which is precisely the point of Nix, you configure it how you want it.

    I tried installing it for fun and my /home/$user folder is empty. Is that normal? Like there’s no Desktop, Downloads, Documents, etc folders by default. I picked the GNOME desktop environment at install. Never seen that before.

    This is normal. XDG dirs must be configured manually. Alternatively, home-manager has options for this.

    Good to know! I've not seen any other distribution handle home folders that way. I've even installed previous versions of NixOS and don't remember ever needing to do that. Seems like an odd choice to me, but NixOS has a few of those so it's all good. Definitely not a beginner distro.

    Probably not. There must be something missing in your configuration. Do you have createHome = true for your user?

    When facing issues on nixos, you can easily just share your /etc/nixos/configuration.nix + a description of your error + logs and it'll provide useful context for people. We'll even be able to spin up a VM with your config to see if the bug can be recreated.

    I have a home folder. It's just empty. To answer your question though, no createHome = true is not in my configuration.nix file. I could dump all that, but this is a fresh system. It's clearly an issue with the NixOS installer. I tried it on completely different hardware just now and have the same problem. I solved it by running this series of commands.

    xdg-user-dirs-update
    gio set ~/Desktop metadata::custom-icon-name user-desktop
    gio set ~/Documents metadata::custom-icon-name folder-documents
    gio set ~/Downloads metadata::custom-icon-name folder-download
    gio set ~/Music metadata::custom-icon-name folder-music
    gio set ~/Pictures metadata::custom-icon-name folder-pictures
    gio set ~/Videos metadata::custom-icon-name folder-videos
    gio set ~/Templates metadata::custom-icon-name folder-templates
    gio set ~/Public metadata::custom-icon-name folder-publicshare
    xdg-user-dirs-gtk-update

    I guess it's fine, but not ideal. I could see that confusing the shit out of a more casual user.

    When you say "nixos installer", do you mean the GUI nixos installer? If you have a github account, you can create a bug report. As a KDE user, this has never been a problem for me.
