Yes, same here - xorg is complaining about a Radeon driver by the looks of the message (sorry, forgot to copy it down!) - I'm trying on a Thinkpad T42 which has been running earlier versions of GhostBSD no problem - apart from now saying that there is a segmentation error when running pkg upgrade.
It is a hold problem since the day I started that project and it still happening, it is annoying it is mostly due to Xorg and GDM. For 4.5 I move to PCDM and FreeBSD have made a change lately that might solve the problem with Intel. I will like to help, but without the hardware I can't help.
I hope GhostBSD 4.5 will finally be done with that problem.
