Hi Patrick,
OSMesa (and friends such as OpenSWR) do not need to make use of GLX. In
fact I think it should be disabled completely for that case in both Mesa
and ParaView builds. For eg, when you configure ParaView you'd specify
-DVTK_USE_X=OFF. At least this is how it was in the past. I haven't been
following developments lately. The wiki
<http://www.paraview.org/Wiki/ParaView/ParaView_And_Mesa_3D> has specifics.

Hi,
I'm still trying to build paraview 5.3 with Qt4.8. As paraview
superbuild was failing on my desktop (centos 6.9, Nvidia GPU), I build
paraview by hand and it is running now with and without pvserver
connection
.
The problem went back with building same paraview version on the
cluster frontend: CentOS 6.7, no GPU. The compilation is successfull
but launching paraview I get some errors with OpenGL:
ERROR: In
/kareline/data/begou/PARAVIEW5/paraview/VTK/Rendering/OpenGL2/vtkOpenGLRenderWindow.cxx,
line 825
vtkXOpenGLRenderWindow (0x2280fb0): GL version 2.1 with the
gpu_shader4 extension is not supported by your graphics driver but is
required for the new OpenGL rendering backend. Please update your
OpenGL driver. If you are using Mesa please make sure you have version
10.6.5 or later and make sure your driver in Mesa supports OpenGL 3.2.

I've built and installed mesa from mesa-17.0.4.tar.gz using:
./configure \
PKG_CONFIG_PATH=/share/apps/paraview-5.3.0/lib/pkgconfig \
--prefix=/share/apps/paraview-5.3.0 \
--disable-osmesa --enable-gallium-osmesa --enable-gallium-llvm \
--with-llvm-prefix=/share/apps/paraview-5.3.0
With several requested libraries:
libxshmfence-1.2.tar.gz
libxcb-1.12.tar.gz
libXau-1.0.8.tar.gz
pthread-stubs-0.3.tar.gz
xcb-proto-1.12.tar.gz
libdrm-2.4.70.tar.gz
llvm-4.0.0.src.tar.xz
all under /share/apps/paraview-5.3.0/
I've checked with strace that paraview was loading libGL in
/share/apps/paraview-5.3.0/lib and not the system one, requested by
other application (frontend is in production and I cannont break these
libraries used by other softwares).
I must confess I'm not familiar at all with these libraries and
environments, mesa or osmesa, GPU or not GPU, of screen rendering...
all documentation deeping in obscure details while I'm searching to
understand these concepts.
it is clear for me that on the nodes (without GPU) I will use OSMesa
and no GUI, but on the frontend where I need GUI ???
Thanks for your advices and sorry if this is a very basic lack of
understanding from myself.
Patrick
