🐧 Arch Linux – Post-Installation & Configuration Script

This project contains a comprehensive Bash shell script (install.sh) designed to automate the configuration of an Arch Linux system right after installation. The script installs essential packages, optimizes the package manager, sets up the user environment, and automatically adjusts system services and the bootloader to match your hardware.

🚀 Key Features

• Hardware Detection (GPU): Automatically detects your graphics card (NVIDIA, AMD, Intel) and installs the appropriate 32-bit libraries (including Vulkan) and loads the correct modules for Early KMS.
• Package Management:
• Installs a wide selection of system, development, multimedia, and gaming applications via pacman.
• Automatically installs yay for AUR support and uses it to install selected packages (e.g. Google Chrome, Brave, Ventoy).
• Configures Flathub integration.
• Removes a predefined list of unnecessary packages (bloatware).
• pacman.conf Optimization: Enables parallel downloads (ParallelDownloads), syntax coloring (ILoveCandy), and blocks unnecessary locale files (keeping only PL and EN) and documentation to save disk space.
• Bootloader & Plymouth: Configures a silent boot (quiet splash, hidden GRUB/systemd-boot menu) and a Plymouth splash screen.
• Terminal Environment: Changes the default shell to ZSH, installs the Oh My Zsh framework and the Powerlevel10k theme, and adds fastfetch on startup.
• Privacy & Networking: Forces the use of Cloudflare's secure DNS servers (1.1.1.1).
• Services & Security: Configures the firewall (UFW) and enables key system services (Bluetooth, fstrim, libvirt/KVM).

⚠️ Prerequisites

1. A fresh Arch Linux installation.
2. sudo configured — the script must not be run as root; run it as a regular user with sudo privileges.
3. An active internet connection.

💻 Installation & Usage

1. Clone the repository to your disk bash git clone https://github.com/bartko4321/arch-config.git

2. Navigate to the folder bash cd arch-config

3. Make the script executable bash chmod +x install.sh

4. Run the script (without sudo!) bash ./install.sh

5. Running inside a chroot bash sudo -u username /home/username/arch-config/install.sh

Once finished, the script will automatically reboot your computer.

🛠 Configuration & Customization

The script is written to be easily tailored to your needs. Open install.sh in any text editor to:

• Modify the list of packages to remove in the PACKAGES_TO_REMOVE section.
• Add/remove official packages in the SYSTEM_PKGS array.
• Add/remove AUR packages in the AUR_PKGS array.
• Change default services (e.g. disable UFW or libvirt).

📁 Optional File Structure

The script checks for and copies additional files if they are present in the same directory:

• .update.sh – an optional user update script.
• System Maintenance.desktop – a desktop/menu shortcut file.

• bleachbit/ folder – pre-configured settings for BleachBit.
