 1 Introduction
There are enough differences between the Gnome 3 and Gnome 2 panel that may cause you to look for something else. This guide will help you setup XMonad to be used with Unity 2D.
Unity 2D is different from Unity 3D in a few significant ways: Unity 2D comprises a set of programs (panel, launcher, etc) and allows you to choose which window manager you want to use. On the other hand, Unity 3D is a Compiz plugin, so it can be seen as a window manager (like Gnome Shell).
This guide assumes you will run Unity 2D using the Gnome 3 libraries.
 2 Preparation
Install Unity 2D:
% sudo apt-get install unity-2d-panel
Create the following files:
# /usr/share/applications/xmonad.desktop [Desktop Entry] Type=Application Encoding=UTF-8 Name=Xmonad Exec=xmonad NoDisplay=true X-GNOME-WMName=Xmonad X-GNOME-Autostart-Phase=WindowManager X-GNOME-Provides=windowmanager X-GNOME-Autostart-Notify=true # /usr/share/gnome-session/sessions/xmonad.session [GNOME Session] Name=Xmonad Unity-2D Desktop RequiredComponents=gnome-settings-daemon; RequiredProviders=windowmanager;panel; DefaultProvider-windowmanager=xmonad DefaultProvider-panel=unity-2d-panel # /usr/share/xsessions/xmonad-gnome-session.desktop [Desktop Entry] Name=Xmonad GNOME Comment=Tiling window manager TryExec=/usr/bin/gnome-session Exec=gnome-session --session=xmonad Type=XSession
 3 XMonad Setup
First, configure XMonad as you would for it to be used in Gnome. Next you need to make the following changes to your
Add the following to your manage hook:
myManageHook = composeAll [ -- other hooks, , className =? "Unity-2d-panel" --> doIgnore , className =? "Unity-2d-launcher" --> doIgnore -- more hooks
The Unity 2d panel declares 2 different window types and that seems to be confusing XMonad, so you'll have to explicitely add a gap at the top:
import XMonad.Layout.Gaps myLayouts = gaps [(U, 24)] $ -- your other layout configuration
Now you should be ready to login. Make sure you choose the
XMonad GNOME session in GDM.
 4 Unity 2D setup
Unity 2D is still using GConf for its configuration, so using GConf Editor, look under
desktop/gnome/unity-2d/launcher to see how you can tweak the launcher behavior.
