A flake-based NixOS configuration with Hyprland window manager support.

Tuned to squeeze every bit of performance out of your system. It's not in a drop-and-go state, but if you're willing to tweak a few things (like replacing my username), you should be mostly set.

There are a few ways we could improve for easier sharing. I'd appreciate suggestions/PRs.

• Hyprland/Wayland desktop

  • Hyprland session via GDM (Wayland), programs.hyprland.enable with xwayland.enable
  • Autostarts waybar, dunst, hyprpaper, hypridle
  • Hyprland env/theme: QT_QPA_PLATFORMTHEME=qt6ct, Wayland-first (NIXOS_OZONE_WL=1, MOZ_ENABLE_WAYLAND=1, QT_QPA_PLATFORM=wayland, GDK_BACKEND=wayland)
  • Keybinds for DPMS, screenshots (grim/slurp), media/brightness, app launchers, workspace mgmt

• Lock screen and idle

  • hyprlock with PAM enabled (security.pam.services.hyprlock = { };)
  • hypridle drives DPMS/off-on and lock-before-sleep
  • Wallpaper templated into hyprpaper and hyprlock via activation script

• Waybar + notifications

  • Waybar modules for Hyprland workspaces/window, audio, network, CPU/Mem, brightness, AMD GPU, weather, BTC price, public IP, clock, tray
  • Dunst notifications; custom scripts installed into ~/.config/waybar/scripts/

• NixOS, flakes, channel

  • Flake-based config on nixos-unstable
  • Inputs: hyprwm/Hyprland and noblepayne/pretty-switch
  • Formatter: alejandra
  • Declarative activation copies Hyprland/Waybar configs into $HOME each rebuild

• Portals, audio, screenshare

  • xdg.portal.enable = true with Hyprland preferred and GTK as extra
  • PipeWire + WirePlumber, ALSA/Pulse/JACK enabled (screenshare and pro-audio friendly)

• Performance and reliability

  • Zen kernel, ZRAM (zstd) enabled
  • BPF auto-tuning (services.bpftune) and BCC tools
  • Nix store auto-optimise; weekly GC
  • systemd OOM tuning for nix-daemon
  • Btrfs root with fstrim and autoscrub
  • CPU governor set to "performance"

• Graphics

  • Wayland + XWayland
  • RADV (Mesa) by default; 32-bit graphics enabled for gaming

• Gaming

  • Steam (Gamescope session, Remote Play and dedicated server firewall openings)
  • Lutris, wineWowPackages.staging, winetricks, vulkan-tools
  • hardware.steam-hardware.enable = true (controllers/udev rules)

• Virtualization and containers

  • libvirtd + virt-manager
  • Docker with weekly auto-prune

• Files and desktop integration

  • Dolphin with kio-extras, kio-fuse, kio-admin, thumbnailers, ark
  • udisks2 for mounting; KDE polkit agent
  • Clipboard (wl-clipboard, cliphist), screen capture (grim/slurp), OSD, portals

• Networking and security

  • NetworkManager, Tailscale, OpenSSH, Netdata
  • Polkit enabled; sudo for wheel without password
  • Firewall currently disabled (intended choice)

• Shell and tooling

  • Fish shell + Atuin; rich dev/multimedia/system toolsets
  • Secrets kept out of the repo; systemd user service imports GITHUB_TOKEN from ~/.config/secrets/github_token at login

1. You'll need to update the path with your home dir. Search for chrislas, replace with your user. (Would like suggestions for improvement)

• Waybar visuals: Blur + slight transparency enabled (Hyprland layerrule = blur, waybar and ignorealpha 0.1; CSS background rgba(…, 0.75)).
• Module chips: Each module wrapped with padded, rounded boxes to reduce jitter when values change. Fixed minimum widths for key modules.
• Left window title: hyprland/window moved to the left next to workspaces.
• Added modules: MPRIS (media), idle inhibitor (icons: ☀️ active / 🌙 inactive), Gamemode indicator, reboot button (⏻ with rofi confirm), brightness menu icon (🖥️).

• Keybind: SUPER+B opens a rofi menu with common steps/presets.
• Waybar: monitor icon launches the same menu.
• Script location: installed to ~/.local/bin/rofi-brightness (tilde path used in configs for portability).
• Backends: Uses brightnessctl for kernel backlight or ddcutil for external monitors. For DDC:
  • Ensure hardware.i2c.enable = true;
  • Add your user to the i2c group
  • Have ddcutil installed

• Requires services.gvfs.enable = true, services.gnome.gnome-keyring.enable = true, and glib-networking package.
• Avahi mDNS discovery uses services.avahi.nssmdns4 = true; (renamed option).
• Optional: services.davfs2.enable = true; for WebDAV filesystem mounts (GVFS WebDAV also available).

• GTK theme: Tokyo Night GTK; icons: Papirus; cursor: Bibata.
• Qt: qt.platformTheme = "gnome" with qt.style = "adwaita-dark" for consistency; adwaita-qt{,6} and qt6ct present.
• GTK4/libadwaita apps mostly follow dark mode + accent; GTK3/Thunar follow the full theme.

• ~/.local/bin/rofi-brightness must be installed (activation script handles this) and rofi available.
• User should be in groups used by this setup: wheel, networkmanager, i2c, docker, etc.
• External monitor brightness: verify ddcutil detect sees your display; otherwise only kernel backlight works.
• Waybar CSS: GTK CSS is strict; avoid unsupported units/properties. This config uses conservative em widths and supported rules.
• Reboot button uses rofi for confirmation; adjust to your preferred prompt if you don't use rofi.

The following keybindings are available on nixstation for managing the 4-monitor layout:

Monitor Layout:

• Screen 1: Above center (GIGA-BYTE M27Q) - 2560x1440
• Screen 2: Left vertical (ASUS PB278) - 1440x2560 (rotated 90°)
• Screen 3: Center/main (ASUS PB278) - 2560x1440
• Screen 4: Right vertical (ASUS PB277) - 1440x2560 (rotated 90°)

Workspace Support:

• Each monitor supports its own set of workspaces (1-10)
• SUPER+1..0 switches to workspace 1-10 on the currently focused monitor
• SUPER+SHIFT+1..0 moves the active window to workspace 1-10 on the currently focused monitor
• Workspaces are independent per monitor, allowing for complex multi-monitor workflows
