<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 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>

<p class="MsoNormal" style="mso-margin-top-alt:auto;mso-margin-bottom-alt:auto">So I started testing Paraview v5.0.1 Linux and it doesn’t work with RealVNC v4, or v5.1.1 or v5.3 (dies with Segmentation fault without even displaying a screen). Earlier versions
of Paraview work but not 5.0.1. I am not very familiar with VNC. Are there graphics or other options in VNC that need to be tuned that I could refer to my sysops?<o:p></o:p></p>
