The nixos-hardware "common-*" profiles the installer selects cover the
basics (microcode, the Intel/AMD VA-API media stack, weekly fstrim), and
power.nix adds thermald + power-profiles-daemon. This adds the gap above
them, generically and detected at install time.
New modules/nixos/hardware.nix exposes a vendor-keyed nomarchy.hardware.*
surface — broadly-beneficial bits default ON when the vendor is detected
(opt-out), heavy/experimental bits behind opt-in toggles:
- intel.enable -> GuC/HuC (i915.enable_guc=3); intel.computeRuntime
(opt-in: intel-compute-runtime + vpl-gpu-rt)
- amd.enable -> amd_pstate=active + radeonsi VA-API env; amd.rocm.enable
+ amd.rocm.gfxOverride (opt-in: ROCm HIP/OpenCL)
- fingerprint.enable -> fprintd; fingerprint.pam (opt-in: login + sudo)
- npu.enable (opt-in/experimental) -> the in-kernel driver
(amdxdna/intel_vpu) keyed by vendor; userspace runtime is BYO
hardware-db.sh now detects Intel/AMD, a fingerprint reader (libfprint USB
vendor IDs) and an NPU (Intel VPU / AMD XDNA PCI IDs), emitting NOMARCHY
lines the installer bakes into system.nix — safe defaults active, opt-ins
commented. Audited against the commons to avoid double-setting.
Verified: flake check green; a toggles-on build has amd_pstate=active +
i915.enable_guc=3 in kernel-params and ships fprintd.service; detection
runs correctly on the (AMD Ryzen-AI) dev machine. On-hardware verification
of the AMD/NPU/Intel-compute runtime bits is still pending.
Docs: template commented examples, README option table, ROADMAP status.

My Nomarchy machine
- Overwrite the placeholder hardware config with the real one:
nixos-generate-config --show-hardware-config > hardware-configuration.nix - Set
flake.nixup once (Nomarchy repo URL, your username, optionally ahardwareProfilefrom https://github.com/NixOS/nixos-hardware — an unknown name fails the rebuild with suggestions). After that the flake is never touched again: your machine lives insystem.nix(hostname, services — the login user is created fromusernameautomatically) andhome.nix(your packages). git init && git add -A— flakes only see tracked files, includingtheme-state.json.- System:
sudo nixos-rebuild switch --flake .#default - Desktop:
nix run home-manager -- switch --flake .#me(afterwards justhome-manager switch --flake .#me— it's installed) - Clone/symlink this directory to
~/.nomarchy(or exportNOMARCHY_PATH) sonomarchy-theme-syncknows where the state lives.
Day-to-day:
nomarchy-theme-sync list # 21 shipped presets
nomarchy-theme-sync apply gruvbox # writes state + home-manager switch
nomarchy-theme-sync bg next # cycle wallpapers (instant, no rebuild)
The system layer only needs nixos-rebuild when you change system.nix.
