Xmonad Session
To start an Xmonad session, look for a drop-down menu while you are logging in to Linux. Once you install Xmonad, there should be an option for Xmonad in this drop-down list. This drop-down list gives you your choice of desktop window managers.
Change Caps Lock to Control
One of the first things I do. Thanks to this page: http://www.noah.org/wiki/CapsLock_Remap_Howto
$ vim ~/.profile
and add the following line to the top:
setxkbmap -layout us -option ctrl:nocaps
This is also a whiz-bang handy one-liner to have for those times when you need to "fix" a keyboard from the command line.
Very Very Basic Usage
When you first start xmonad, you can open a terminal with Alt Shift Enter
Move focus with Alt + J and Alt + K
Change tiling modes with Alt + Space
Resize with Alt + H and Alt + L
Swap focused window with its next door neighbor with Alt + Shift + J and Alt + Shift + K
Close focused window with Alt + Shift + C
Log out with Alt + Shift + Q
Control number of windows displayed in master pane on left: Alt + . and Alt + ,
Workspace N switch with Alt + N
Configuration
The configuration file is not there by default
It is in ~/.xmonad/xmonad.hs
Reconfigure after editing it with Alt + Q
Sample Xmonad Config File
--
-- xmonad example config file.
--
-- A template showing all available configuration hooks,
-- and how to override the defaults in your own xmonad.hs conf file.
--
-- Normally, you'd only override those defaults you care about.
--
import XMonad
import System.Exit
import qualified XMonad.StackSet as W
import qualified Data.Map as M
-- The preferred terminal program, which is used in a binding below and by
-- certain contrib modules.
--
myTerminal = "xterm"
-- Width of the window border in pixels.
--
myBorderWidth = 1
-- modMask lets you specify which modkey you want to use. The default
-- is mod1Mask ("left alt"). You may also consider using mod3Mask
-- ("right alt"), which does not conflict with emacs keybindings. The
-- "windows key" is usually mod4Mask.
--
myModMask = mod1Mask
-- The mask for the numlock key. Numlock status is "masked" from the
-- current modifier status, so the keybindings will work with numlock on or
-- off. You may need to change this on some systems.
--
-- You can find the numlock modifier by running "xmodmap" and looking for a
-- modifier with Num_Lock bound to it:
--
-- > $ xmodmap | grep Num
-- > mod2 Num_Lock (0x4d)
--
-- Set numlockMask = 0 if you don't have a numlock key, or want to treat
-- numlock status separately.
--
myNumlockMask = mod2Mask
-- The default number of workspaces (virtual screens) and their names.
-- By default we use numeric strings, but any string may be used as a
-- workspace name. The number of workspaces is determined by the length
-- of this list.
--
-- A tagging example:
--
-- > workspaces = ["web", "irc", "code" ] ++ map show [4..9]
--
myWorkspaces = ["1","2","3","4","5","6","7","8","9"]
-- Border colors for unfocused and focused windows, respectively.
--
myNormalBorderColor = "#dddddd"
myFocusedBorderColor = "#ff0000"

-- Layouts:
-- You can specify and transform your layouts by modifying these values.
-- If you change layout bindings be sure to use 'mod-shift-space' after

--
-- The available layouts. Note that each layout is separated by |||,
-- which denotes layout choice.

-- Window rules:

-- workspace.
--
-- To find the property name associated with a program, use
-- > xprop | grep WM_CLASS
-- and click on the client you're interested in.
--
-- To match on the WM_NAME, you can use 'title' in the same way that

Status Bar
You can create a status bar with xmobar
Start it like this:
$ xmobar &
This will use the configuration file in ~/.config/xmobar/xmobarrc or ~/.xmobarrc
