Thanks for the bug report. We have reviewed the information you have provided
above, and there is some additional information we require that will be helpful
in our diagnosis of this issue.
Please attach your X server config file (/etc/X11/xorg.conf) and X server log
file (/var/log/Xorg.*.log) to the bug report as individual uncompressed file
attachments using the bugzilla file attachment link below.
Could you please also try to run without any /etc/X11/xorg.conf whatsoever and
let X11 autodetect your display and video card? Attach to this bug
/var/log/Xorg.0.log from this attempt as well, please.
We will review this issue again once you've had a chance to attach this information.
Thanks in advance.

Xorg.0.log after removing /etc/X11/xorg.conf
I removed my /etc/X11/xorg.conf and then did a reboot. It appears to properly
configure the display but I didn't get a gdm login. I think that's because the
most recent NetworkManager isn't working right instead of a problem with X,
After disabling NetworkManager, I was able to login. The gdm problems I was
having have nothing to do with this.
OK, back to basics -- I overlooked that you tried to make dual-head working with
system-config-display. It probably doesn't work much anymore. In the brave new
world we are now, xrandr is used instead. Could you try to play with that, please?
After reading a short tutorial about xrandr (heard about it, never used it) I
got it working fairly quickly.
