Here's the xorg.conf file that is created by system-config-display:
# Xorg configuration created by system-config-display
Section "ServerLayout"
Identifier "single head configuration"
Screen 0 "Screen0" 0 0
InputDevice "Keyboard0" "CoreKeyboard"
EndSection
Section "InputDevice"
# keyboard added by system-config-display
Identifier "Keyboard0"
Driver "kbd"
Option "XkbModel" "pc105+inet"
Option "XkbLayout" "us"
EndSection
Section "Device"
Identifier "Videocard0"
Driver "nv"
EndSection
Section "Screen"
Identifier "Screen0"
Device "Videocard0"
DefaultDepth 24
SubSection "Display"
Viewport 0 0

EndSubSection

If I exit to runlevel 3 with that xorg.conf, I can't startx with one
monitor or two connected... X crashes with output like this:
(II) Primary Device is: PCI 01@00:00:0
The PCI device has a kernel module claiming it.
This driver cannot operate until it has been unloaded
(EE) No devices detected.
Fatal server error:
no screens found
If I remove xorg.conf entirely or change the above xorg.conf
to use nouveau, startx works with one monitor connected, but
not with both. If I startx with both monitors connected, X crashes
with output like this:
...

But if I startx with one monitor connected and then plug in the
second monitor after X is up, it runs fine with a single active
monitor. Then, if I run system-config-display, it activates the
second monitor (although it used to allow me to configure
the geometry and now it doesn't). If I click on cancel
instead of ok, it doesn't create the xorg.conf, so the next
time I reboot, I just have to remember to unplug the second
monitor and it will work.
So, it I think there are at least three separate problems
I'm having.
1) an nv driver bug
2) a nouveau driver dual head bug
3) a feature has been removed from system-config-display that
allows me to specify the dual head geometry. But at least
