What is a Window Manager? A Beginner’s Guide to Linux WMs

This week, we’ll be exploring window managers—a key part of the Linux experience that many users may not fully understand. Whether you’re a beginner looking to switch from a desktop environment or a power user seeking better workflow efficiency, this guide will help you navigate the world of tiling, floating, and hybrid window managers.


What is a Window Manager?

A window manager (WM) is a core part of a graphical user interface (GUI) that controls how application windows are arranged, moved, and resized on your screen. Unlike a desktop environment (DE), which includes a full suite of applications and utilities, a window manager focuses solely on managing windows.


Why Use a Window Manager?

Many Linux users prefer standalone window managers over full desktop environments for customization, efficiency, and resource savings. Here’s why:

  • 🖥 Lightweight – Uses fewer system resources than a full desktop environment.
  • Faster Workflow – Keyboard-driven window management can speed up navigation.
  • 🎨 Highly Customizable – Configure keybindings, window behavior, and appearance.
  • 💾 Minimalist – Reduces unnecessary background services.

Types of Window Managers

There are three primary types of window managers:

1️⃣ Stacking (Floating) Window Managers

These operate like traditional GUIs, where windows can overlap each other, much like stacks of paper on a desk.

📌 Examples: Openbox, Fluxbox, KWin (KDE’s built-in WM), Metacity (GNOME’s classic WM)

Pros:
✅ Familiar for most users
✅ Easy to manage with a mouse
✅ Works well for casual or multimedia use

Cons:
❌ Can become cluttered
❌ Requires manual window placement


2️⃣ Tiling Window Managers

Windows are automatically arranged to maximize screen space without overlapping.

📌 Examples: i3, Sway (Wayland-based i3 alternative), bspwm, dwm

Pros:
✅ Efficient use of screen space
✅ Optimized for keyboard-driven workflows
✅ Ideal for programming and multitasking

Cons:
❌ Learning curve for new users
❌ Less intuitive mouse usage


3️⃣ Hybrid (Dynamic) Window Managers

These allow switching between tiling and floating modes.

📌 Examples: KWin (KDE), Mutter (GNOME), AwesomeWM, Xmonad

Pros:
✅ Best of both worlds—flexibility and efficiency
✅ Adaptable to different workflows
✅ Can behave like a full DE

Cons:
❌ More complex configuration
❌ May require scripting for full potential

How to Try a Window Manager

1️⃣ Install a Window Manager:

  • Fedora: dnf install i3
  • Ubuntu: apt install i3
  • Arch Linux: pacman -S i3

NOTE: If you are running i3 on Fedora or Arch you need to login to an Xorg session, not a wayland session, Sway is a fork of i3 for Wayland.

2️⃣ Log out and choose your WM in the login screen.
3️⃣ Learn keybindings and customize your config file!

Final Thoughts

Window managers provide customization, efficiency, and speed unmatched by traditional desktop environments. Whether you prefer tiling for productivity, floating for familiarity, or hybrid for flexibility, there’s a WM suited to your needs.
