[Paraview-developers] [Non-DoD Source] Re: What is the minimum nvidia driver level that works with ParaView 5.3.0 (UNCLASSIFIED)

Chuck,

I have tested it on Excalibur SRD graphic nodes which are using hardware 
acceleration of the video cards.
I have also tested it on the ARL utility server SRD nodes, which I do not 
believe are hardware accelerated.
Both types of SRD nodes are segfaulting on startup if that environment 
variable is not set.

Thanks,

Joe

Since you're running it under SRD, I don't think you're actually getting a 
connection to the GPU.  I suspect it's likely an issue with VirtualGL and VNC 
and how it's forwarding things on to the underlying GPU.  Not that I have any 
idea how to fix it right now but that's probably a good place to start 
looking.

	Hmm okay. In which case it may indeed be the issue with offscreen

	fixes are merged in so we can try again.
