power: drop the disk swapfile and hibernate
Remove the 58 GiB swapfile on the LUKS root, along with what depended
on it: resumeDevice, resume_offset, the suspend-then-hibernate logind
actions and HibernateDelaySec. zram is now the only swap, capped at
8 GiB so it can't cut into memory needed for large LLM/GTT loads.

Lid, idle and the suspend key now do plain s2idle suspend; the power
key powers off. This loses the hibernate fallback that used to end a
spurious-wake loop; acpi.ec_no_wakeup=1 and the gsd-power tweaks are
now all that keeps s2idle stable.

NixOS

Assisted-by: Claude (claude-opus-4-5 → claude-opus-4-6 → claude-opus-4-7 → claude-opus-4-8 → claude-fable-5)

Flake-based NixOS configuration for a ThinkPad P14s Gen 6 (AMD), tracking nixos-unstable.

Highlights

  • Secure Boot via lanzaboote
  • Secrets: sops-nix with age — xray config, WireGuard, SSH keys, private routes/hosts; encrypted files stay out of the repo (only .example structure files are tracked), decrypted to /run/secrets at activation
  • Desktop: GNOME on Wayland, AMD GPU
  • Local LLMs: Ollama with ROCm (gfx1151) + Lemonade for XDNA2 NPU serving via nix-amd-ai
  • Networking: Xray VLESS+Reality with sing-box TUN, WireGuard, WWAN modem
  • Gaming: Steam with gamescope, declarative Flatpaks via nix-flatpak
  • Litecoin Core (MWEB): vendored package build, revived after removal from nixpkgs
  • Power: AMD P-State tuning, zram swap ahead of disk swap

Layout

flake.nix              # inputs and host definition
configuration.nix      # entry point, imports modules
modules/               # one module per concern (boot, desktop, ollama, xray, ...)
secrets/               # sops-encrypted (age) secrets, gitignored; .example files document structure

Usage

sudo nixos-rebuild switch --flake /etc/nixos#meow

Fresh install: restore secrets/ and the age key (/var/lib/sops-nix/key.txt) from out-of-band backup first.
