Sorry for taking so long to reply.
After reading a number of pages off google, it seems like one possible work around was uninstalling the gnome-screensaver package. I did that, and now I can log out, but I cannot start X up again without my monitor going into the "no signal" mode. (for some reason I also lost the ability to "reset", "shut down", or "switch user" in the system menu in gnome.
Anyway, I installed openbox to see if the problem was gnome specific. I can log out from openbox, but if I try to start X again (just using startx), it goes into "no signal" mode, so it would seem that the problem is with X and not with the window managers.
As far as I can tell, I am running the latest version of all the installed packages, and have updated my ports. (I'm completely new to non-windows systems, so I could be wrong about everything being updated).
I'm using FreeBSD 8.1 RC2 amd64
I'm using a Radeon HD 2400 Pro on a 32" 1080p tv over HDMI using the "radeon" driver.
Here are sections from my
xorg.conf

Please let me know it there's anything else you need to help identify the error.
Thanks for the help.
