I need some advice on how to turn on RANDR.
I have a few systems with nVidia GPU 5xx and 6xx series. Latest kmod
drivers, multiple monitors with Xinerama enabled.
Newer systems work fine but I have once that been upgraded since before
the 2 were compatible. I have libXrandr installed but it doesn't seem
to be enabled.

Thank you Florian and Phil. I got it to work. Here's the procedure I
used. I make no claim that it is optimal.
------------------------------------------------------------------------
*Problem*:
When using multiple monitors with nVidia drivers some programs require
RANDR (Resize, rotate, AND, Reflect). If it's not available, they exit
with an error available in $HOME/.xsession-errors or the terminal window
noting RANDR is not available.
If Scientific Linux was upgraded from older versions during which RANDR
and kmod-nvidia were incompatible, it is necessary to "fix" /etc/xorg.conf.
*Prerequisites*:
My reading suggests that to use RANDR with nVidia drivers those drivers
must be newer than 302.x I am using 310.32, current as of 2013-3-10. I
have not verified when this support was added.
The package libXrandr must be installed. I'm using 1.3.0 but have no
idea what the minimum version might be.
*Procedure*:
* Remove /etc/xorg.conf (sudo mv /etc/xorg.conf /etc/xorg.conf.bak)
* Reboot (X will not start) into command line terminal. Or log in
remotely via ssh
* run nvidia-settings with no options. This will create a default
xorg.conf
* reboot (X will start)
* Now run the NVIDIA X Server settings from the System menu, or
nvidia-config-display from the command line.
o On the X-server Display Configuration tab, Configuration should
be TwinView
o As far as I can tell you have to argue with program to convince
it how you want the rest of the options to display.

I can now run AisleRight Solitaire without going through a VNC server
and for free I can also run my scanner software but I seem to still have
issues with my teleconferencing software but that might be something else.
Thanks for all your help.
