Implements battle-tested gaming optimizations and sets up infrastructure for better package management based on community best practices analysis.

Flake Inputs

  • nix-gaming - SteamOS-inspired platform optimizations and low-latency audio
  • home-manager - Foundation for user-level declarative configuration

System Services (common.nix)

  • PipeWire low-latency: quantum 64, rate 48000
  • zramSwap: zstd compression at 50% memory
  • fwupd: firmware update support
  • power-profiles-daemon: dynamic power management

Gaming Profile

  • Platform optimizations via nix-gaming.platformOptimisations
  • Added: LACT (GPU control), vkbasalt (post-processing), discord

Dev Profile

  • Added: meld (visual diff), dbeaver-bin (DB GUI), insomnia (API testing)

Home Manager is wired but not yet used - user configurations can be added via home-manager.users.<username> blocks when ready to migrate packages from system-level.

Pull request overview

Integrates community-proven NixOS gaming optimizations and adds a Home Manager module baseline to support future migration of user-level configuration into declarative Home Manager profiles.

Changes:

  • Added nix-gaming flake input and enabled its platform optimizations in the gaming profile.
  • Added Home Manager as a NixOS module with global/user package wiring (no per-user HM config yet).
  • Expanded gaming and dev profiles with additional tools (vkBasalt/LACT/Discord; delta/meld/dbeaver/insomnia) and added common system services (zramSwap, fwupd, power-profiles-daemon, PipeWire low-latency config).

File Description
modules/gaming.nix Imports and enables nix-gaming platform optimizations; adds gaming-related packages (vkbasalt, lact, discord).
modules/dev.nix Adds/organizes dev tooling packages (delta, meld, dbeaver-bin, insomnia).
modules/common.nix Enables zram swap, fwupd, power-profiles-daemon; configures PipeWire low-latency settings.
flake.nix Adds nix-gaming and home-manager inputs; wires Home Manager module into shared module set.

The new flake inputs nix-gaming and home-manager are referenced via mutable GitHub URLs without a committed flake.lock, so each build can pull arbitrary code from the upstream default branches. If either upstream repository or the GitHub supply chain is compromised, a malicious update could be fetched and evaluated as part of the NixOS build, leading to remote code execution or full system compromise. Pin these inputs via a committed flake.lock or explicit immutable revisions and update them only through a controlled process.
