Xwindows drives the underlying graphical interface of most if not all Unix/Linux computers providing a GUI. It was developed in 1984 at MIT. After around 35 years of development, tweaking and adding of new hardware and ideas, it is generally acknowledged to be a bit of a beast. It should be remembered that the common configuration at time of development was a single mini running X providing individual views to Xterminals in a timesharing system. Nowadays the norm is X providing a single screen on a desktop or laptop.

All of this means that there are many ways of achieving the same thing and many slightly different things that can meet the same purpose. In modern X versions sometimes you can get away with limited or no configuration. In the last few years the boast is that X is self configuring. Certainly the best practice rule of thumb is less configuration is better - that is only configure what is wrong.

xmonad

xmonad is a dynamically tiling X11 window manager that is written and configured in Haskell. In a normal WM, you spend half your time aligning and searching for windows. xmonad makes work easier, by automating this.

If xdg/awesome default config loads instead of .config/awesome, this is due to error in the rc.lua.

Colours

The color format in awesome is either a standard X color name (blue, darkblue, lightred, etc) or a hexadecimal formatted color (#rrggbb or #rrggbbaa). By using the hexadecimal format, you can also specify an alpha channel: that means that #00ff00 will draw pure green, but #00ff00aa will set the alpha channel to ‘aa’ and will blend the green with the color under it.

Text format

You can use Pango markup in a text string. This allows formating the text rendered inside widgets. Pango markup documentation can be found in the Pango documentation at http://library.gnome.org/devel/pango/stable/PangoMarkupFormat.html.
