Custom Arch Linux installation ISO with KDE Plasma, NVIDIA drivers, and automated installation.

The ISO boots into a live KDE Plasma desktop with:

• Username: liveuser
• Password: None (auto-login)
• Sudo access: Enabled (passwordless)
• Desktop: KDE Plasma on Wayland via SDDM
• Network: NetworkManager enabled

An automated installer script is available on the desktop (or via terminal) that installs:

• Partitioning: GPT with EFI (FAT32, 2048 MiB) + Btrfs root
• Bootloader: systemd-boot with Intel microcode
• GPU: NVIDIA open-source DKMS drivers with Wayland support
• Desktop: KDE Plasma on Wayland via plasma-login-manager
• Audio: PipeWire
• Locale: UK (en_GB.UTF-8, uk keyboard, Europe/London timezone)
• User: Customizable username with sudo access

1. Boot from the ISO
2. Automatically logs in to KDE Plasma as liveuser
3. Full desktop environment with networking, browser, file manager, etc.

Option 1: Double-click the "Arch Installer" desktop icon

Option 2: Open Konsole and run:

sudo /root/scripts/arch-install.sh

The installer will:

1. Detect and partition the disk
2. Install all packages (base system, KDE, NVIDIA, applications)
3. Configure locale, timezone, and keyboard layout
4. Set up NVIDIA drivers with Wayland/DRM support
5. Install systemd-boot bootloader
6. Create your user account
7. Reboot into the installed system

Build-time configuration is set in .github/workflows/build.yml:

env:
  EFI_SIZE: 2048              # EFI partition size in MiB
  LOCAL_ZONE: Europe/London   # Timezone
  LOCALE: en_GB.UTF-8         # System locale
  KEYMAP: uk                  # Console keymap
  X11_KEYMAP: gb              # X11/Wayland keymap
  HOSTNAME: arch-javid        # Hostname for installed system
  USERNAME: javid             # Username for installed system
  PASSWORD: password          # User password for installed system

The project uses two separate package lists:

1. packages.x86_64 - Live ISO packages (used by mkarchiso)

   • Minimal base system + SDDM + KDE Plasma desktop
   • Basic applications and partitioning tools
   • Critical: Must include mkinitcpio-archiso for live boot

2. packages.txt - Installed system packages (used by pacstrap)

   • Full system with NVIDIA drivers + complete KDE suite
   • Uses plasma-login-manager instead of SDDM

Kernel command line includes:

nvidia-drm.modeset=1 nvidia_drm.fbdev=1 quiet splash

• Driver: nvidia-open-dkms (requires linux-headers)
• Modules: Early loading via initramfs (MODULES in /etc/mkinitcpio.conf)
• Modprobe config:
  • DRM modesetting enabled (/etc/modprobe.d/nvidia.conf)
  • VRAM preservation across suspend (/etc/modprobe.d/nvidia-power.conf)

The ISO is built automatically via GitHub Actions on every push to main. To build locally:

# On Arch Linux:
sudo pacman -S archiso
sudo mkarchiso -v -w work -o out .
