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
                Depth     24
        EndSubSection
EndSection

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
