Can I add X to my server after install? or I installed from the Server ISO and it didn't install X, how do I install X?

The easiest way to install X (and a GUI system) is to use the yum groupinstall feature.

First you can see all the yum groups available with the command:

yum grouplist

You can install X and Gnome or KDE like this:

yum groupinstall "X Window System" "GNOME Desktop Environment"

or

yum groupinstall "X Window System" "KDE (K Desktop Environment)"

You may also want to add some other groups from the list like "Graphical Internet" or "Office/Productivity"
