Hello, I get the following error when I try to run a script with pvpython on a virtual machine (Ubuntu 16.04): ERROR: In /build/paraview-arsa8T/paraview-5.0.1+dfsg1/VTK/Rendering/OpenGL/vtkXOpenGLRenderWindow.cxx, line 333 vtkXOpenGLRenderWindow (0x3acfad0): bad X server connection.

If you don’t want to install an X server, you can use a binary of ParaView built against osmesa. We are going to produce official release binaries built against osmesa starting with ParaView 5.6.

As I did not write the script myself, I cannot tell if opening a window is required in my case because I only used Paraview GUI by the pas…

Fantastic, I am glad it is working.
