The laptop was still on the Hyprland-era Pantheon commit while the desktop moved to KDE Plasma 6 + Limine and split system.nix into focused modules. This brings over everything that isn't hardware, unchanged, so both machines stay diffable: - Plasma 6 on Wayland with SDDM, Konsole, gruvbox icons, KDE MIME defaults (replaces Pantheon/LightDM; libreoffice-qt6 replaces the GTK build) - Limine bootloader with the gruvbox theme, replacing systemd-boot - system.nix split into boot/networking/locale/nix-settings/security - flakes + nix-command, sysctl hardening extras (yama, tcp_timestamps), geoclue off, captive-portal probe off - package parity: obs-studio, lmms, go, qemu, KDE utilities, lean SDR++ and rtl_433 overrides with hardware.rtl-sdr Hardware and power are adapted rather than copied: - hardware.nix keeps the AMD 680M + RTX 4050 PRIME offload setup, asusd and supergfxd, v4l2loopback webcam and the DualSense ERTM fix; OpenRGB and the desktop's single-GPU block are dropped, keyboard lighting is asusctl - power.nix is new: power-profiles-daemon for Plasma's profile switcher, lid-close handling via the current logind.settings.Login spelling, powertop/acpi, notes on asusctl charge limits - no acpi_enforce_resources=lax, ACPI owns the EC asusd drives here - touchpad defaults, and firewall openings so the hotspot script's shared connection can hand out DHCP/DNS - pinentry-qt instead of the desktop's leftover pinentry-rofi, blueman dropped in favour of Plasma's bluedevil hardware-configuration.nix stays tracked here (unlike the desktop, which gitignores it) since it's the only record of this machine's disk layout.

# nexoniarz-config-nixos-laptop
|
|
|
|
My personal NixOS system configuration tailored for daily use on an
|
|
**ASUS TUF Gaming A15 (FA507NU)**. Same layout and same choices as
|
|
[nexoniarz-config-nixos](https://github.com/Nexoniarz/nexoniarz-config-nixos)
|
|
(the desktop), with the hardware and power modules swapped for this machine.
|
|
|
|
## Overview
|
|
|
|
- **OS:** NixOS 26.05 (unstable channel)
|
|
- **Desktop:** KDE Plasma 6 on Wayland (KWin), SDDM
|
|
- **Bootloader:** Limine
|
|
- **Terminal:** Konsole
|
|
- **Shell:** Zsh
|
|
- **Audio:** PipeWire
|
|
- **CPU:** AMD Ryzen 5 7535HS
|
|
- **GPU:** AMD Radeon 680M (iGPU, drives the internal panel) + NVIDIA RTX
|
|
4050 Max-Q (dGPU, PRIME render offload only — run anything through it with
|
|
`nvidia-offload <command>`)
|
|
- **Laptop control:** `asusctl` (fan curves, keyboard backlight, battery
|
|
charge limit) + `supergfxctl` (dGPU power-state switching)
|
|
|
|
## Layout
|
|
|
|
| File | Contents |
|
|
|---|---|
|
|
| `configuration.nix` | Imports only |
|
|
| `hardware-configuration.nix` | Generated by `nixos-generate-config`, don't hand-edit |
|
|
| `modules/boot.nix` | Limine, kernel, zram/swap |
|
|
| `modules/networking.nix` | NetworkManager, firewall, DNS-over-TLS, MAC randomization |
|
|
| `modules/locale.nix` | Timezone, locale, console keymap |
|
|
| `modules/nix-settings.nix` | Nix features, GC, unfree |
|
|
| `modules/security.nix` | sysctl hardening, sudo, firejail, GnuPG, polkit |
|
|
| `modules/hardware.nix` | Hybrid graphics (PRIME offload), ASUS daemons, Bluetooth, I2C, RTL-SDR, webcam loopback, tablet, printing |
|
|
| `modules/power.nix` | Power profiles, lid/suspend behaviour, battery notes |
|
|
| `modules/audio.nix` | PipeWire |
|
|
| `modules/desktop.nix` | Plasma, SDDM, touchpad, fonts, theming |
|
|
| `modules/users.nix` | Account, shell, Steam, Flatpak |
|
|
| `modules/apps.nix` | Installed packages, nix-ld |
|
|
| `modules/default-apps.nix` | MIME associations |
|
|
| `modules/scripts.nix` | Custom scripts in `modules/scripts/` |
|
|
|
|
Small custom CLI helpers live in `modules/scripts/`: encrypted vault toggle,
|
|
metadata stripping, brightness control (kernel backlight or DDC/CI), Wi-Fi
|
|
hotspot, system telemetry, weather fetch.
|
|
|
|
## Differences from the desktop config
|
|
|
|
Everything outside hardware is kept identical on purpose. What differs:
|
|
|
|
- `modules/hardware.nix` — AMD iGPU + NVIDIA dGPU on PRIME offload with
|
|
`asusd`/`supergfxd`, instead of the desktop's single NVIDIA card and
|
|
OpenRGB motherboard lighting. Keyboard lighting is `asusctl aura` here.
|
|
- `modules/power.nix` — laptop-only module: power-profiles-daemon (Plasma's
|
|
power profile switcher), lid-close behaviour, `powertop`/`acpi`.
|
|
- `modules/desktop.nix` — adds touchpad defaults and the Wayland/Ozone flag.
|
|
- `modules/boot.nix` — no `acpi_enforce_resources=lax`; ACPI owns the EC that
|
|
`asusd` talks to on this machine.
|
|
- `modules/networking.nix` — firewall openings for the hotspot script's
|
|
`ipv4.method shared` dnsmasq.
|
|
- `modules/security.nix` — `pinentry-qt` (Plasma) rather than the desktop's
|
|
leftover `pinentry-rofi`.
