[Paraview] pvbatch offscreen rendering problems

[Carrie E. Spear (Cont, CISD/ARL)]

Utkarsh,

When I do an ldd pvbatch appears to be using the correct libraries GL 
libraries (I am building agains mesa-7.0.4, could it be that my version 
of mesa is too old). I ran the following test:

bash-3.2$ echo $DISPLAY
:0.0
bash-3.2$ unset DISPLAY
bash-3.2$ echo $DISPLAY

bash-3.2$ mpirun -np 4 pvbatch --use-offscreen-rendering 
testParallelRender.py
: cannot connect to X server
--------------------------------------------------------------------------
mpirun has exited due to process rank 0 with PID 4770 on
node ls08270-l.arl.army.mil exiting without calling "finalize". This may
have caused other processes in the application to be
terminated by signals sent by mpirun (as reported here).
--------------------------------------------------------------------------

When I have DISPLAY set it works perfectly.

Thanks,
Carrie
