[Paraview] Cron job and ParaView

[Scott, W Alan]

OK, taking small steps here,  what is OSMesa, and want is Mesa?  Utkarsh and I had this discussion, but I never understood the difference.

Having just googled the difference, If I understand correctly, OSMesa actually means Off Screen Mesa, and is compiled into Mesa.  Otherwise, you get Mesa – software rendering, but into a GLX window?

You are correct – I am not building OSMesa.  Thus, my problem?

Are you sure you are building with osmesa? Just using mesa is not sufficient.

Subject: [EXTERNAL] [Paraview] Cron job and ParaView

I have a user that is trying to run ParaView in a cron job, and keeps getting the following error on PV 4.4.0: 4.4.0/ParaView4/VTK/Rendering/OpenGL/vtkXOpenGLRenderWindow.cxx, line 542 vtkXOpenGLRenderWindow (0x5197850): bad X server connection

Has anyone tried to do this, and figured out a solution?  User has tried running a build I did – which attaches to Mesa – and has –use-offscreen-rendering turned on, and is running pvbatch.  Same error.

Any ideas?

Thanks,

Alan
