CachyOS (Arch) + Hyprland desktop configuration with custom "Dragon Fire" theme. Managed declaratively with Nix Flakes + Home Manager.

4K Display	1080p Display

• Source Color: #fd5622 (vivid orange)
• Accent: #e53935 (red)
• Background: dark greys (#181616, #1e100c)
• Style: Kanagawa Dragon inspired with Material You palette

CachyOS is an Arch-based distribution optimized for performance out of the box:

• Performance-tuned kernel (BORE scheduler, x86-64-v3/v4 optimized packages)
• Stable enough for a daily driver - rolling release with the full Arch ecosystem, but with sane defaults and a graphical installer
• Tried Bazzite OS for a few months - ran into persistent video issues (screen tearing, compositor glitches) that were never a problem on CachyOS, so switched back
• Caution with LUKS + TPM2: kernel or bootloader updates can break automatic TPM2 unlock - always keep a recovery key and re-enroll after major updates

• CachyOS (or Arch Linux)
• Nix package manager (standalone, not NixOS)
• System packages installed via pacman (Hyprland, pipewire, docker, etc.)

# First time: install Nix
curl --proto '=https' --tlsv1.2 -sSf -L https://install.determinate.systems/nix | sh -s -- install

# Deploy (first time)
cd ~/Documents/dotenv
nix run home-manager -- switch --flake .#$USER

# Deploy (after changes)
home-manager switch --flake .#$USER

# Rollback to previous generation
home-manager switch --rollback

# List all generations
home-manager generations

If Hyprland breaks or is unusable (GPU issues, driver update, etc.), MATE is available as a fallback desktop:

# Install MATE
sudo pacman -S mate mate-extra

# Select MATE from the login screen (GDM/SDDM session picker)

Home Manager manages the user environment declaratively:

• Dotfiles: symlinked to ~/.config/, ~/.vimrc, etc.

• CLI tools: installed via Nix in an isolated store (doesn't conflict with pacman)

• Idempotent: running home-manager switch multiple times always produces the same result

• Rollback: every deployment creates a generation you can switch back to

• External flake inputs: tools like git-identity-manager are pulled in as flake inputs and added to home.packages

System-level packages (Hyprland, pipewire, docker daemon, fonts, etc.) remain managed by pacman.

Automated home directory backup using restic + rclone to kDrive (Infomaniak cloud storage).

Secrets management chain:

• Backup encryption password is stored in Bitwarden Secrets Manager (BWS)
• BWS access token is stored locally in ~/.config/bws/$USER-desktop.key
• Restic retrieves the password from BWS on each run - never stored on disk

How it works:

• home-backup backup - incremental backup of $HOME to kDrive via rclone
• home-backup prune - retention policy: 7 daily, 4 weekly, 6 monthly snapshots
• home-backup restore <id> - restore a specific snapshot
• Desktop notifications via notify-send on success/failure

See scripts/home-backup.sh for the full script.
