At the bottom of the SOLVED message, I noted that one program didn't
work. That one is SeeVogh teleconverencing (research.seevogh.org).
Today I discovered a Matlab application (one of mine) that produced the
same symptoms.
To skip to the end: Setting Matlab to use software opengl fixes that
problem.
*Symptoms
*When running a program that encounters this problem, X11 crashes and
the current session logs out bringing you to the login window. All
programs are immediately terminated.
When running NVidia settings from the menu and attempting to check
OpenGL/GLX Information, that program exits immediately.
*Error messages and logs
*Since these programs crash the only information I've found is in
$HOME/.xsession-errors.old and /var/log/Xorg.log.old
The NVidia settings program, .xsession-errors:
Gdk-ERROR **: The program 'nvidia-settings' received an X Window
System error.
This probably reflects a bug in the program.
The error was 'BadWindow (invalid Window parameter)'.
(Details: serial 771 error_code 3 request_code 137 minor_code 4)
(Note to programmers: normally, X errors are reported asynchronously;
that is, you will receive the error a while after causing it.
To debug your program, run it with the --sync command line
option to change this behavior. You can then get a meaningful
backtrace from your debugger if you break on the gdk_x_error()
function.)
aborting...
Matlab and SeeVogh have:
Window manager warning: gnome-session: Fatal IO error 11 (Resource
temporarily unavailable) on X server :0.0.
/var/log/Xorg.log.old has:
Backtrace:

[ 37353.205]
*Request
*I've attached my xorg.conf, which I think is the most probable source
of the problem.
I'd appreciate any suggestions on how to fix this so these programs can
use hardware OpenGL, or how to get everything to use software OpenGL as
a workaround while still being able use the GPU for crunching.
Also any avenues to allow me to dig deeper would help.
Thanks,
Joe

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.
