My working environment with Xmonad

Fire a terminal, fire another terminal and tail some logs, open your browser and point to the web page you are developing, open your IDE and open three or four tabs with the code you suspect is causing the bug, put some breakpoints, alt-tab to the first terminal start your system under test, connect your debugging IDE to your system, perform some operations to your browser, catch the breakpoint, switch back and forth the code tabs, etc… This daily routine common to most developers, involves grabbing the mouse, arranging some windows, and switching context continuously. This creates a cognitive overload and a lack of productivity because developers are doing tasks not directly related to the task at hand.

This is the reason I don’t use Gnome any more and I’ve switched to Xmonad a tiling window manager that can be controlled almost exclusively with the keyboard. With this fully configurable window manager, I can move, resize, minimize, arrange, customize all the visible windows, move windows between workspaces, all with my hands not leaving the keyboard.The only thing I have not been able to accomplish is having the UrgentHook working for Skype. The Linux version of Skype fails to set the WM_URGENT X11 event when a new chat opens, and if I’m not in that workspace I don’t get any notification besides the bell. Still thinking about a good workaround, any ideas?

Here is a screenshot of xmonad in action with  some applications in it,

If you plan to install Xmonad in your computer, use version 0.10 or superior because it solves some nasty problems with Java applications. In case it is not yet ready for your favourite distribution, follow these instructions. In order to have this configuration working, just write the following 3 files:

  • ._xsession_ with the programs you need to start when the session begins (network manager, batery manager, etc…). Put it in your $HOME dir.

  • ._xmobarrc_ with the configuration of your handy textual status bar . Put it in your $HOME

  • xmonad.hs with the configuration of the window manager itself. Put it under $HOME/.xmonad

xmonad.hs is a pure Haskell file for configuring the window manager, no XML, not another fancy configuration language. Some comments to the configuration file

  • lines 23-26, send Thunderbird and Skype to their dedicated workspaces

  • line 29, name the workspaces

  • lines 32-50, define new key combinations, for navigating the tiling windows, send windows to background and toggle between the tiled arrangement and focusing the whole screen into one window

  • lines 52-55, define how I want the windows to be arranged. Basically, create a specific configuration for Skype in its dedicated workspace, and for the rest of workspaces, don’t hide the menu, allow navigation with the cursors and minimize unwanted windows.

  • lines 57-77, ensemble the main xmonad window manager with the desired configuration. Spawn the status bar, and append the predefined layouts, keybindings and window hooks. Redefine some keys and fool Java setting the name of the Window Manager to LG3D in order to avoid problems with focus.
