System->Administration->Display window does not show up after installing kmod-nvidia


I am attempting to get dual monitors working and I have made some progress but now am stuck.

First thing I did was `yum install kmod-nvidia` and reboot. After rebooting X did not start and I figured out the problem was my dual nvidia 6800's trying to use SLI. Alright, I don't need SLI so I took one out and now have just the one 6800, which has a DVI and VGA output. Now the system boots up and both monitors are working :-) but there are two issues:

One, as the title says is that going to System->Administration->Display has no effect. The system asks for the root pw and thats it, no display window comes up.

Secondly, my screens are on the wrong side: i.e. right and left screens are backwards. Can I fix this through my xorg.conf file? Here is what it looks like right now:
Code:
# Xorg configuration created by livna-config-display

Section "Files"
	ModulePath   "/usr/lib/xorg/modules/extensions/nvidia"
	ModulePath   "/usr/lib/xorg/modules"
EndSection

Section "ServerFlags"
	Option	    "AIGLX" "on"
EndSection

Section "Device"
	Identifier  "Videocard0"
	Driver      "nvidia"
	Option	    "Twinview"
	Option	    "AddARGBGLXVisuals" "True"
EndSection

Section "Extensions"
	Option	    "Composite" "Enable"
EndSection
Thanks,
Chris

to change the way twin veiw is round you need the line

Code:
Option          "TwinViewOrientation" "RightOf"
in the "Device section".

You shouldn't have to edit X.org in Fedora. have you tried running the nvidia graphical configuration program.

Thanks Arch, I haven't used Fedora too much yet and this is the first time I've tried to set up dual screens, so I wasn't quite sure what the best way to do it was. I added that line to the xorg.conf file (it was "LeftOf" that worked) and it is working correctly now.

Does the fact that I installed the nvidia drivers supercede the gnome display screen? I wonder if that's why its not coming up?

Anyways, it's working well enough now that I'm happy =)

I'm speaking from somone who hasn't used fedora to much but while using ubuntu(with gnome) the nvidia driver installed an app called NVIDIA X server settings on system>>administration or launch from command line using nvidia-settings.

If I use the default Display configure I get warning message:
Code:
It appears that your graphics driver does not support the necessary extensions to use this tool.  Do you want to use your graphics driver vendor's tool instead?
So I assume that nvidia takes over completely.
