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.

That's exactly what I am doing as well ("unset DISPLAY" that is), and
seems to work well. Is this a debug build. Can you track down where
the error message is coming from? I am not sure where this error
message is coming from since it doesn't look like a paraview message
and a quick "grep" didn't yield any result. When paraview spews a
display error, it looks something as follows:
Process id: 0 >> ERROR: In
/home/utkarsh/Kitware/ParaView3/ParaView3/VTK/Rendering/vtkXOpenGLRenderWindow.cxx,
line 542
vtkXOpenGLRenderWindow (0x3be47e0): bad X server connection.
DISPLAY=Process id: 0 >> ERROR: In
/home/utkarsh/Kitware/ParaView3/ParaView3/VTK/Rendering/vtkXOpenGLRenderWindow.cxx,
line 344
vtkXOpenGLRenderWindow (0x3be47e0): bad X server connection. DISPLAY=p0_29057:
Also make sure that OSMESA_INCLUDE_DIR, and OSMESA_LIBRARY are set
correctly. Just for consistency sake, set the following to default
values:
VTK_USE_OFFSCREEN=OFF
VTK_USE_DISPLAY=ON
These need not be changed at all for using OS mesa in ParaView.

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

Carrie,
I just tried it with CVS ParaView and I could not reproduce it. Can
you reproduce this when running on a single node? Try running ldd on
pvbatch, is it getting the right OpenGL libraries?

That sounds fishy, let me take a look. I'll get back to you.

Good Morning,
I am currently having issues with paraview-3.8.0 and paraview-3.9.0 when
trying to use pvbatch and offscreen rendering. When I run with my
DISPLAY
variable set, I don't have any issues, when the DISPLAY variable is not
set
it fails with the "cannot connect to X server error". I have built
paraview
with the following flags to support the offscreen rendering
capabilities:
OPENGL_INCLUDE_DIR
OPENGL_gl_LIBRARY
OPENGL_glu_LIBRARY
OPENGL_xmesa_INCLUDE_DIR
OSMESA_INCLUDE_DIR
OSMESA_LIBRARY
VTK_OPENGL_HAS_OSMESA=ON
VTK_USE_OFFSCREEN=ON
VTK_USE_DISPLAY=OFF
I have built paraview-3.6.2 with these flags and the pvbatch offscreen
rendering works perfectly without the DISPLAY variable being set, the
same
does not work for 3.8.0 and 3.9.0. Am I missing a new flag for these
packages? The mesa version I am using is 7.0.4.
The pvbatch command I am running is:
mpirun -np 4 pvbatch --use-offscreen-rendering testParallelRender.py
Thanks in advance for your help,
Carrie
