I'm agree. I was just testing to understand what is happening.

In my laptop I have 3 options (pressing enter buttom) for
VTK_RENDERING_BACKEND:  OpenGL, OpenGL2 and None,
but in my desktop I have only one: OpenGL.

I compile paraview in my laptop (ubuntu 16.04) and my desktop (ubuntu
14.04) with exactly the same options in ccmake, in particular: OpenGL.
In my laptop 'Export to pdf' works perfect.
Is this related this the nvidia driver? In my desktop I have installed
nvidia driver, but in my destop I have not installed nvidia driver.

You are right: in the paraview version from ubuntu repository says
"ParaView 5.0.1 (Legacy Rendering Backend)" in the tittle bar.
Also, in my both compiled paraview 5.0.1 appears "ParaView 5.0.1 (Legacy
Rendering Backend)" in the tittle bar too.

Now, in my desktop I'm trying compiling with OpenGL2 option (the option
doesn't comes hiting the enter button, instead of my laptop, but I chosed
writting it), and crossing my fingers.

I appreciate any ideas or suggestions (I don't have more), to find a way for
fix this 'little' problem: to have the export to pdf option.

Thanks again.
