[Paraview] pvserver: Could not find a decent visual

[Vandetta, Terralyn]

I currently have paraview 3.98.1 installed on a CentOS 6.2 cluster.  The head node has X installed, but the compute nodes do not.  I have built Paraview with the OSMesa, but cannot seem to get it to work on this server.  I have a Debian system with the same 3.98.1 installation built with OSMesa, and have no problems.

I have tried running with mpi and also just a single instance, and am using pvserver, with a 3.98.1 client on my windows machine.  I can make the connection on my client, and open a file.  As soon as I attempt to view the file, in every incantation I get similar error messages:

Waiting for client...
Connection URL: cs://hpc.fsl.orst.edu:11111
Accepting connection(s): hpc.fsl.orst.edu:11111
Client connected.
ERROR: In /usr/local/src/ParaView-3.98.1-source/VTK/Rendering/OpenGL/vtkXOpenGLRenderWindow.cxx, line 383
vtkXOpenGLRenderWindow (0x1ebf3c0): Could not find a decent visual

[Further message, included in attached file]

Based on information from the paraview wiki, I was under the impression that I should be able to use: pvserver -use-offscreen-rendering to force it to ignore any X connections, but so far, I have had no luck.  The compute nodes do not have X installed at all, and so I tried the reverse connection on the client, with the -use-offscreen-rendering and -ch -rc options, with the same results.  Am I misunderstanding the use of OSMesa and -use-offscreen-rendering?

Any assistance would be appreciated.
