[Paraview] pvbatch offscreen rendering problems

Wed Apr 7 14:06:38 EDT 2010

So, we're really stumped.

- Paraview (pvbatch) 3.6.2 works exactly as we'd expect.
- pvbatch 3.8.0/3.9.0 fail with the "can't open display" error.  If we 
set a display variable, pvbatch works, but that's not really a solution.
- All three are using the same exact Mesa library and use the same 
CMakeInit file during the build.  
- We've also built by hand (without a CMakeInit file) and get the same 
error.
- See the same display error when running pvbatch serially

Not really sure where to turn.
