<div class="moz-cite-prefix">Hi,<br>
<br>
haven't read the entire thread, but if you want remote
visualization and HAVE GPUs, why don't you use VirtualGL? Then you
would start it with "vglrun paraview", and ParaView would get a
GPU buffer for direct rendering. It is very easy to setup, just
google for VirtualGL, and if something does not work, email me...<br>
<br>
Cheers...<br>

<p class="MsoNormal">I suspect the GPU is not getting used
by the VNC server and thus falling back to a software
OpenGL implementation with older mesa and not a new enough
OpenGL support. Different VNC servers on Linux have
different capabilities, with some able to reach their
underlying GPU and some not. From your VNC session, can
you open up a terminal and run: glxinfo | grep '^OpenGL'
? That should be more telling.<o:p></o:p></p>

<p>Hi Dennis, a few questions:<o:p></o:p></p>
<p>Are you using the binaries from <a
moz-do-not-send="true"
href="http://paraview.org/" target="_blank">paraview.org</a> or
did you build it yourself?<br>
Does the machine with the vnc server have a GPU
you're trying use?<br>
You said previous versions of paraview worked.
Does that include 5.0 and 4.x or just 4.x?<o:p></o:p></p>

I started testing Paraview v5.0.1 Linux

work but not 5.0.1. I am not very
