Hi Kent,<br><br>Not sure if this will help, but one area that gave me trouble when trying to compile without X11 was VTK/Rendering/vtkOpenGLExtensionManager.cxx.<br><br>Check out the file <paraview-build-dir>/VTK/Rendering/vtkOpenGLExtensionManagerConfigure.h, it may reveal some defines related to GLX extension loading. I had to hack some cmake files to make the ExtensionManager behave without X11. If this turns out to be the problem, I can tell you specifically what I did.<br>

Thanks! Sorry it took so long to try. The results are exactly the same in both the version using MPI (run with mpiexec -np 2 pvbatch) and the one without (run with pvbatch).<br>
<br>
Both display windows. The non-mpi version doesn't crash because it finds an X server.<br>
<br>
I know gdb and my versions have been compiled for debugging. Can you think of a key location where I could stop it and look at some variables? If we could convince the non-mpi version to refrain from looking for an X server we have probably fixed the mpi version too.<br>

Here's a patch to enable use-offscreen-rendering. Can you verify if that helps?<br>

Ah. I didn't realize that pvbatch did not support --use-offscreen-rendering.<br>

Yes, and have verfied what is being used with "ldd pvbatch". Note that the<br>
Wiki reference you provide is about setting up a server, not batch.<br>
<br>
pvbatch does not support the option "--use-offscreen-rendering" and should<br>
not need that option when the cmake option "use offscreen rendering" has<br>
been set.<br>
<br>
Thanks!<br>
