[Paraview] pvbatch offscreen rendering problems

[Utkarsh Ayachit]

That's exactly what I am doing as well ("unset DISPLAY"  that is), and
seems to work well. Is this a debug build. Can you track down where
the error message is coming from? I am not sure where this error
message is coming from since it doesn't look like a paraview message
and a quick "grep" didn't yield any result. When paraview spews a
display error, it looks something as follows:

Process id: 0 >> ERROR: In
/home/utkarsh/Kitware/ParaView3/ParaView3/VTK/Rendering/vtkXOpenGLRenderWindow.cxx,
line 542
vtkXOpenGLRenderWindow (0x3be47e0): bad X server connection.
DISPLAY=Process id: 0 >> ERROR: In
/home/utkarsh/Kitware/ParaView3/ParaView3/VTK/Rendering/vtkXOpenGLRenderWindow.cxx,
line 344
vtkXOpenGLRenderWindow (0x3be47e0): bad X server connection. DISPLAY=p0_29057:

Also make sure that OSMESA_INCLUDE_DIR, and OSMESA_LIBRARY are set
correctly. Just for consistency sake, set the following to default
values:
VTK_USE_OFFSCREEN=OFF
VTK_USE_DISPLAY=ON

These need not be changed at all for using OS mesa in ParaView.
