Arcolinux: Migrating to Arch Linux on Steroids: Comprehensive Guide to Installing Multiple Desktops

🎯 Key Objectives

• Reduce the learning curve of Arch Linux using Arcolinux (Arch modified to be more accessible).
• Explore multiple desktop environments (KDE, Xfce, i3, AwesomeWM) to suit technical workflows.
• Optimize the system for intensive workloads (running AI models like GPT4All or Deepseek 7B).
• Encourage autonomy in advanced customization and resource management.

🛠️ Preparation: Before You Install

Minimum Requirements

• CPU: x86_64 with AVX/AVX2 support (required for local AI models).
• RAM: 8 GB (16 GB recommended for 7B models).
• Storage: 30 GB free + external USB 3.0 swap drive (optional but useful).
• Base System: Stable internet connection (Arch installs from the network!).

  Why Arcolinux?

• Advantages vs. Vanilla Arch: Graphical installer, preconfigured repositories, and ready-made desktop profiles.
• Analogy: If Arch is an empty toolbox, Arcolinux is that box with illustrated manuals and pre-organized common tools.

📥 Step-by-Step Installation

1. Download and Verify

1. Get the ISO: ArcolinuxD ("all-inclusive" version).
2. Burn the ISO: Use Ventoy to create a bootable USB (preserves space to store other files).

3. Backup: Save your critical data to the external drive (partitioning will erase everything!).

2. Graphical Installation (Calamares)

• Recommended partitioning for AI:
• / (root): 50 GB (ext4).
• swap: 2x RAM (e.g., 16 GB if you have 8 GB RAM).
• /home: Remaining space (your AI models will live here).
• Pro-tip! If using an external drive: sudo mkswap /dev/sdX1 && sudo swapon /dev/sdX1.

3. First Boot

1. Update: sudo pacman -Syu.
2. Install yay (AUR Helper):

git clone https://aur.archlinux.org/yay.git
cd yay
makepkg -si

How to Switch Between Desktops

1. Selection in GDM/SDDM:

• On the login screen, click the gear icon.

2. In Terminal:

   startx /usr/bin/[desktop-name]

Swap Configuration on External Drive

1. Format the drive:

   sudo parted /dev/sdX mklabel gpt
   sudo parted /dev/sdX mkpart primary linux-swap 0% 100%

2. Activate it permanently: Edit /etc/fstab and add:

   /dev/sdX1 none swap defaults 0 0

Performance Improvement

• Prioritize processes: Use nice -n -20 ./your_AI_model (highest CPU priority).
• Limit background services:

  sudo systemctl disable bluetooth.service cups.service
