Of course the geek in me could not stay away for long. Am learning high level Unix networking and to get started I need to know how the X windows system works and how to use it. According to this wikipedia article, X windows is a computer software system and network protocol that provides a graphical user interface for networked computers. Pretty neat, huh! Well, I found a really good introductory tutorial here for newbies like me (though I can't really call myself that anymore having finished LPI1). Enjoy.
