Hi Every one!  
I used to use VM Ubuntu to run Paraview and I had no problem. Now I am trying to use X2Go which is much easier to use. I can open Paraview without problem but when I want to load a controlDict on it to analyse a case it gives me the following error:

In build/paraview-Nojbrj/paraview 5.1.2+dfsg1/paraviewcore/ServerImplementation/core/vtksiproxy.cxx, line 310  
vtkSi source proxy 0x56b01ba0d90 : failed to create vtkxdmfreader aborting for debugging purposes

and it closes Paraview suddenly. Do you know what should I do?

Thanks

I suspect `PARAVIEW_ENABLE_XDMF2` CMake variable is OFF (which is the default) in your build. Try enabling that.
