The patch seems to have resolved the issue related to the DISPLAY
variable. Thanks!

Looks like the patch should resolve this issue. I've committed it to
CVS. Let me know if that doesn't work. We'll commit it to 3.8 branch
soon.

Rick/ Carrie,
My paraview is still building and will be a while before I can try
this out. But attached is a patch that I think will solve this issue.
Can you try it out?
Thanks

I was writing a response when it struck me, are you building with
PARAVIEW_BUILD_QT_GUI ON? That's possible the only difference between
your build and mine. I am going to turn on PARAVIEW_BUILD_QT_GUI and
try to reproduce the problem.

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?

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
