Hi Chuck
thanks for all these details. Finaly I had to install a dedicated version of
mesa as the update to 11.0.7 from ELrepo was breaking one of our licensed
software (ANSYS) and I had to roll back to 10.4.3.:-[
I've compiled mesa-17.0.4 (with llvm-4.0.0, libdrm-2.4.70, xcb-proto-1.12,
pthread-stubs-0.3, libXau-1.0.8, libxcb-1.12, libxshmfence-1.2 prerequisites)
and all seams running fine now with hardware rendering (?). In my VNC session:
$ glxinfo
....
direct rendering: Yes
...
OpenGL renderer string: Gallium 0.4 on llvmpipe (LLVM 4.0, 256 bits)
OpenGL version string: 3.0 Mesa 17.0.4
....
so am I using the GPU (direct rendering is set to yes) or the CPU (if llvmpipe
is software rendering) ?

If you're running via VNC then unfortunately you won't be using the GPU
(unless you get more creative with something like VirtualGL). You're only
going to be able to use the CPU based renderer in Mesa.
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.
So, Mesa got OpenGL 3.2 support in 10.6.5, but not all of the drivers
implemented it until much later.
OpenGL renderer string: Gallium 0.4 on llvmpipe (LLVM 3.6, 256 bits)
llvmpipe is Mesa's software renderer
OpenGL version string: 2.1 Mesa 11.0.7
Older versions of Mesa may have supported OpenGL 3.2 at it's core but the
llvmpipe driver still took a while to catch up.
So which minimal mesa version is required for paraview 5.3 ?
It wasn't until Mesa 12 that OpenGL 3.2 was properly supported and reported by
all Mesa drivers. With some versions of 11, though, it works *enough* that
you can fake it by exporting the environment variable GL_VERSION_OVERRIDE=3.2,
so give that a try. If you instead want to just use the linux binaries from
paraview.org <http://paraview.org>, we build those on EL6 and include a very
recent copy of mesa with it that you can make paraview use with:
paraview --mesa-swr
That instructs ParaView to use it's own copy of Mesa and the OpenSWR parallel
CPU rasterizer.
