which package from KDE, chapter 28 is necessary to install for having a GUI
 

Hi
I want to install a GUI on my LFS7.2
I select KDE and now I don't know which package from the KDE core is nessecary to install to having a GUI, I want more less package be installed.
OR must I install all package in the KDE core !!!!!!!!

my another question is with which order I install packages in kde core(chapter 28)?

Caveat: I don't use kde I use Xfce
The core packages are just that, core, you will cause yourself all sorts of problems later if you try to skip core components, install them all and in the order that the book says.
