Asgard
The NixOS desktop workstation, with Niri, Noctalia, gaming support, and Secure Boot.
Asgard is an x86_64-linux NixOS workstation: an Intel CPU with an AMD GPU,
dual-booting Windows. It is exported as nixosConfigurations.asgard and its
source is
hosts/nixos/asgard/.
What the host selects
- Profiles: the NixOS desktop and development profiles, plus the Secure Boot and gaming modules directly.
- User:
cbrst, with Zsh as the login shell and membership inwheelandgamemode. NixOS owns the account itself; Home Manager owns what is inside the home directory. - Home Manager: embedded in the system configuration with the shared
system package set (
useGlobalPkgs) and per-user package installation (useUserPackages). It imports the user'shome.nixand the development, desktop-linux, and gaming home profiles.
Host-specific values
| Setting | Value |
|---|---|
| Hostname | asgard |
| Time zone | Europe/Berlin |
| Settings override | gaming.vrrOutput set to the AOC AG276QZD2 monitor, enabling on-demand VRR in Niri |
| Tailscale | cbrst is the Tailscale operator, so the tray and CLI work without sudo |
| Blacklisted modules | brcmfmac is blacklisted. The onboard BCM43602 Wi-Fi is unused (the host is wired), and the driver fails to enter D3, which aborts suspend and can leave the GPU unable to resume |
| Extra overlay and cache | Affinity overlay and the cache.forall.systems binary cache |
Boot loader
Asgard boots with Limine, with Secure Boot signing enabled and up to ten generations in the menu. An extra entry chain-loads the Windows Boot Manager. The menu runs at 2560×1440 and is themed with the Meowsoot dark palette: no wallpaper, a dark backdrop, and Meowsoot colours for the help text and the terminal palette.
Hardware
hardware-configuration.nix describes the real disks and must be regenerated
for any other machine. It enables:
- Linux firmware, 32-bit graphics support, AMD GPU in the initrd, and Intel microcode updates.
- The Btrfs layout described in Installing Asgard, with zstd compression on every subvolume.
- An NTFS games volume at
/mnt/games, owned by the user and mounted withnofailso a missing disk does not block boot.
