I just rebooted after the install.
The bar at the progress bar at the bottom of the screen is stuck. There is a white, blue, and orange bar and Centos 6.3 is in orange. I did press <alt-d> to watch the startup, and everything seemed to have been progressing OK. Then the bar came back and nothing. I tried <alt-d> again and nothing.
So I switched terminals, <alt-F3> and got a login, and am now logged in as root. Nothing is being reported being added to /var/log/messages. Terminals F2-F6 are present; F7 is a blank screeen.
hmmmm. I see something intersting in /var/log/Xorg.5.log it says something like:
(EE) Failed to load module "fbdev" (module does not exist, 0) (II) VESA: driver for VESA chipsets: vesa (--) using VT number 7 (EE) The PCI device has a kernel module claiming it, (EE) this driver cannot operate until it has been unloaded. (EE) Try appending "nomodest" to your boot options (WW) Falling back to old probe method for vesa (EE) No devices detected.
Fatal server error: no screens found

Now what?
