'''Xmonad''' is the tiling window manager that rocks!
 +
 
 +
=Basic Xmonad Keybindings=
 +
Xmonad has very similar keybindings to [[dwm]]. Heres a few of the major ones. They can be redefined by editing the example configuration below.
 +
;Mod-Space
 +
:Changes the tiling method
 +
;Mod-Enter
 +
:Changes the selected tile to the master tile
 +
;Mod-q
 +
:Restarts Xmonad. Note that any open windows and tiles will NOT bet lost
 +
;Mod-Shift-q
 +
:Kills Xmonad, and usually Xorg (depending on how you start X)
 +
;Mod-j
 +
:Select the next tile
 +
;Mod-k
 +
:Select the previous tile
 +
;Mod-Shift-j
 +
:Move the current tile forward
 +
;Mod-Shift-k
 +
:Move the current tile backwards
 +
;Mod-n
 +
:Moves to desktop number n
 +
;Mod-Shift-n
 +
:Move the current tile to desktop n
 +
;Mod-h
 +
:Increase the size of the current tile
 +
;Mod-l
 +
:Decrease the size of the current tile
 +
;Mod-p
 +
:Launches dmenu (if installed)

=Configuring Xmonad=
 +
Edit <code>~/.xmonad/xmonad.hs</code>, then restart Xmonad (Mod-q be default). This configuration file below is the default configuration file, plus a few changes. The mode key is moved from Alt to Super (windows key), the default terminal is set to urxvt instead of xterm, and the PrtSc and Ctr-PrtSc are mapped to scrot (see below for details). Note that this file is written in Haskell, and thus, comments are --. This file also starts xmobar (Xmonad's bar). It is usually a separate package, so if you want this bar, make sure to install it and configure .xmobarrc.

Xmonad is the tiling window manager that rocks!

Basic Xmonad Keybindings

Xmonad has very similar keybindings to dwm. Heres a few of the major ones. They can be redefined by editing the example configuration below.

Mod-Space
Changes the tiling method
Mod-Enter
Changes the selected tile to the master tile
Mod-q
Restarts Xmonad. Note that any open windows and tiles will NOT bet lost
Mod-Shift-q
Kills Xmonad, and usually Xorg (depending on how you start X)
Mod-j
Select the next tile
Mod-k
Select the previous tile
Mod-Shift-j
Move the current tile forward
Mod-Shift-k
Move the current tile backwards
Mod-n
Moves to desktop number n
Mod-Shift-n
Move the current tile to desktop n
Mod-h
Increase the size of the current tile
Mod-l
Decrease the size of the current tile
Mod-p
Launches dmenu (if installed)

Configuring Xmonad

Edit ~/.xmonad/xmonad.hs, then restart Xmonad (Mod-q be default). This configuration file below is the default configuration file, plus a few changes. The mode key is moved from Alt to Super (windows key), the default terminal is set to urxvt instead of xterm, and the PrtSc and Ctr-PrtSc are mapped to scrot (see below for details). Note that this file is written in Haskell, and thus, comments are --. This file also starts xmobar (Xmonad's bar). It is usually a separate package, so if you want this bar, make sure to install it and configure .xmobarrc.

Ackthet's xmonad.hs and .xmobarrc

For dual head setup, come to IRC and bug Shards_of_Narsil (used to be ackthet) Here is an example .xmobarrc:

Config { font         = "-*-terminus-*-*-*-*-12-*-*-*-*-*-*-u"
             , bgColor      = "#000000"
             , fgColor      = "#00FFFF"
             , position =  Top
             , lowerOnStart = False
             , commands     = [ Run Network "eth0" ["-L","0","-H","32","-l", "green", "--normal","orange","--high","red"] 10
                              , Run Network "wlan0" ["-L","0","-H","32","-l", "green", "--normal","orange","--high","red"] 10
                              , Run Cpu ["<cpu0>/<cpu1>","-L","3","-H","50","-l","green","--normal","orange","--high","red"]   10
                              , Run Cpu ["<cpu0>","-L","3","-H","50","-l","green","--normal","orange","--high","red"]  10
                              , Run Memory ["-t","Mem: <usedratio>%", "-l", "green", "--normal","orange","--high","red"] 10
                              , Run Date "%a %b %_d %H:%M" "date" 60
                              , Run CpuFreq ["-t","Freq:<cpu0>|<cpu1>GHz","-L","0","-H","2","-l","green","-n","orange","-h","red"] 10
                              , Run Battery ["-L","50","-H","75","--high","green","--normal","yellow", "--low", "red"] 10
                              , Run StdinReader
                              ]
             , sepChar      = "%"
             , alignSep     = "}{"
             , template = " %StdinReader% }{ %cpu% @ %cpufreq% <fc=#0033FF>|</fc>  %memory% <fc=#0033FF>|</fc> %eth0% <fc=#0033FF>|</fc> %wlan0%  <fc=#0033FF>|</fc> %date% <fc=#0033FF>|</fc> %battery%"
             }

-- xmonad example config file for xmonad-0.9
--
-- 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.
--
-- NOTE: Those updating from earlier xmonad versions, who use
-- EwmhDesktops, safeSpawn, WindowGo, or the simple-status-bar
-- setup functions (dzen, xmobar) probably need to change
-- xmonad.hs, please see the notes below, or the following
-- link for more details:

-- 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       = mod4Mask
 
-- 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.
