SNL: 2.6: Fatal crash: servers bad X server connection.
This issue was created automatically from an original Mantis Issue. Further discussion may take place here.
When running ParaView 2.6, Client/Server on a server that doesn't have a grapics card, I get the following error:
Process id: 0 >> ERROR: In /projects/viz/paraview/src/ParaView/2.6/ParaView/VTK/Rendering/vtkXOpenGLRenderWindow.cxx, line 497 vtkXOpenGLRenderWindow (0xcec7e00): bad X server connection. DISPLAY=:0
Process id: 0 >> ERROR: In /projects/viz/paraview/src/ParaView/2.6/ParaView/VTK/Rendering/vtkXOpenGLRenderWindow.cxx, line 319 vtkXOpenGLRenderWindow (0xcec7e00): bad X server connection. DISPLAY=:0
This is probably the same error as reported on an e-mail listed as PV2.6 Crashes. I am including that e-mail here:
I'm using the released PV2.6 and seeing some strange crashes.
I'm using the Windows Version you guys compiled for the pvclient, and running the PVServer on a linux Cluster. I compiled the server myself with OSMesa ( 6.4.2) & MPI (OpenMPI 1.1.1-1)support, and i'm running it on multiple processors (the number doesn't matter). When I compiled it, I seeded CMake with the following cache:

Problem #1: If I load an ImageData dataset (VTI) and then attempt to use the Clip filter on it, it crashes every time. Also, I get no ghost cells so when I extract an isosurface the process boundaries are clearly visible. I place the Clip Filter at roughly 45-degrees (eyeballed, not much precision) so that it gives me the lower-left half of the data, and when it crashes I get a trace like the following:

If I load the same ImageData Dataset & apply the D3 filter, then attempt to use the Clip filter, it works. I have alot of rendering artifacts (I think due to the Structured->Unstructured conversion) and it takes ALOT of memory, but it works.
