Chris - Yeah, so I’m also not sure how Catalyst might be firing this up. Here’s an example OS_Mesa/cmake command used on one of our generic RHEL6 systems. With this build, we throw the “—use-offscreen-rendering” flag when we fire up the pvserver. I think that the critical flags are “osmesa=ON, mesa=OFF, qt=OFF” ….. Can you use your current build in a traditional client-server configuration to verify that the OS_Mesa is built correctly? That might make it easier to narrow down to a build issue or a Catalyst issue. Just a thought.

Thanks Rick!
I’m running OpenSuse 13.2 64bit. I’m not explicitly starting a pvserver,
because I’m running one of the C++ Catalyst examples, which is located at
ParaView/Examples/Catalyst/CxxFullExample. That is mainly what is confusing
me. I’m not sure if I built ParaView with osMesa incorrectly, or if that
Catalyst example is somehow just telling ParaView ‘Hey, don’t use the
offscreen rendering stuff, just go ahead and keep rendering to the screen.”
I’m thinking that I should be able to test the offscreen rendering
capability independently of that Catalyst example by generating a Python
trace of a pipeline that creates an image output, and the running it with a
command like:
pvserver –use-offscreen-rendering TestScript.py

Stupid question – when you start up the pvserver process, are you passing it
the “—use-offscreen-rendering” flag?
mpirun –np 8 pvserver —use-offscreen-rendering …….
What’s your build platform? I have lots and lots of build scripts I can
share!

Hi All,
I’ve been trying to compile a version of ParaView that uses osMesa. I’ve
tried to follow the process that is explained on the wiki
(Caution-Caution-http://www.paraview.org/Wiki/ParaView/ParaView_And_Mesa_3D
< Caution-http://www.paraview.org/Wiki/ParaView/ParaView_And_Mesa_3D > <
Caution-Caution-http://www.paraview.org/Wiki/ParaView/ParaView_And_Mesa_3D <
Caution-http://www.paraview.org/Wiki/ParaView/ParaView_And_Mesa_3D > > ),
but I haven’t been able to get ParaView to render offscreen. I don’t have
build errors, but when I run something that saves a screenshot I still see a
window pop up on my screen. Would anyone be willing to share their
configuration script/command that they use for compiling ParaView with
osMESA?
Also – If I have a python script that creates a screenshot of some geometry,
do I need to edit it in any way before running it with a version of ParaView
that uses osMesa? Or is all of that handled behind the scenes?
Thank you,
Chris N
