Hi Pete,

You now have a proper graphics card installed on your remote CAVE machine.  
That's great, but unfortunately
because you are connecting remotely, it's not passing along the full 
capabilities of the graphics card.
This is something we've seen before -- we've been able to replicate it by 
sitting at a machine and login as
one user and then ssh to another user and then run CAVE.  
However, Tiffany did discover that when using an older version of 
xorg-xll-server-Xorg, she was able to ssh
as another user and still retain full graphics capabilities.  We assume this 
would mean, with that previous
version, you should be able to remotely connect to your CAVE machine and be 
able to render everything because,
hopefully, the graphics information will also be passed through correctly.

The rpm that's in question is:  xorg-x11-server-Xorg-1.20.4-10.el7.x86_64
She has confirmed that version 1.20 does in fact break the CAVE rendering when 
sshing to a different user.
She was able to run a VM that had version 1.17 and found that even after sshing 
to a different user, the 
graphics still worked and she was able to render the products you've been 
interested in.

At this time we are not sure of an easy way to "downgrade" your rpm.  Hopefully 
we will have more insight or
direction by next week, but I wanted to send you a quick update and fill you in 
with what we know and what
we think might fix your issues with CAVE.

Thank you, hope you have an enjoyable weekend.
