We are Nvidia academic "partners" and need to run Nvidia CUDA. CUDA

probably will install the latest Nvidia driver, although I was hoping to
not do this until we moved to SL 7 (once it goes to a production -- not
beta/testing -- release).
Once this is done, I will report if this solves the problem.
We are running ParaView 4.1.0 64bit (QT version 4.8.2) on more than 20
machines with NVIDIA driver 334.31 and higher without problems. SL6.5.

Your suggestion indeed solved the problem. However, I have installed a
later revision as Nvidia has a more
recent production release:
NVIDIA-Linux-x86_64-340.32.run
Thus, I was chasing a ghost -- the problem really was due to Nvidia.
For those who may need to what to do on a practical basis, here is what
I do:
download the latest production driver from Nvidia
( http://www.nvidia.com/Download/index.aspx?lang=en-us
note that lang=en-us may change depending upon the specifics of your
download, export/import restrictions, etc.)
ctrl-alt-Fx where x is one of the 1 through 7 screens that is not being
used by X11.
su
cp /etc/X11/xorg.conf /etc/X11/xorg-previous.conf
init 2
change to whatever directory contains the installer file (.run above)
sh ./<whatever file name>.run
go though the various steps until it is done (it may report some errors,
etc.)
reboot
log in
using System -> Preferences -> Nvidia X server settings from the pull
down menu, verify that the X server is the current release
(e.g., 340.32 in this instance).
