Hi Chuck<br>
<br>
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.<span
class="moz-smiley-s6"><span>:-[</span></span><br>
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:<br>
$ glxinfo<br>
....<br>
direct rendering: Yes<br>
...<br>
OpenGL renderer string: Gallium 0.4 on llvmpipe (LLVM 4.0, 256 bits)<br>
OpenGL version string: 3.0 Mesa 17.0.4<br>
....<br>
<br>
so am I using the GPU (direct rendering is set to yes) or the CPU
(if llvmpipe is software rendering) ?<br>
<br>

<div>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.<br>

<div>So, Mesa got OpenGL 3.2 support in 10.6.5, but not all
of the drivers implemented it until much later.<br>

<div>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.<br>

<div>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 <a
href="http://paraview.org" target="_blank">paraview.org</a>,
we build those on EL6 and include a very recent copy of
mesa with it that you can make paraview use with:<br>
