Helo to everyone, i upgrade a machine running centos 5.4 to 5.5 this morning. After the update the X start i saw the pointer and a black backgroud only the desktop doesn't appear.
The machine is a barebone with this configuration

the problem was in the Xorg.conf file the old Xorg.conf file was these
Section "Device"
Identifier "Videocard0"
Driver "intel"
EndSection

and i solved the black screen problem changing the driver for i810

Section "Device"
Identifier "Videocard0"
Driver "i810"
EndSection

Welcome to the CentOS fora, and thanks for reporting. I'll add a note to the [url=http://wiki.centos.org/Manuals/ReleaseNotes/CentOS5.5]CentOS 5.5 Release Notes[/url].

I had to do the same thing for my laptop.
Option "DCC" "false"
did not help, but changing from "intel" to "i810" did.
