install xorg pb

[Yohann Desquerre <yohann desquerre wanadoo fr>]

hi all,

my aim is to write a french doc to show how to make a minimum install of 
fedora become useful!

i've got a problem with the install of xorg-x11

i tried yum install xorg-x11 on two differents machines ( one with an 
nvidia graphic chipset and one with an ati one). in the two way yum 
install nvidia-kernel-module.... ok on the first system but why on the 
second.....

whatever the machines i used, i need to reboot before xorg start 
correctly, before the reboot when i try startx i've got a black screen 
and no way to get back the hand on a console (expect connecting from 
another system).

anyone may explain me why the nvidia-module is always installed and why 
i 'have to reboot before to use xorg correctly (at the first time after 
the install)
thanks for help
