<p class="MsoNormal">If we can connect to the remote display using GLX (but not forwarded) then we can render remotely (offscreen but using normal OpenGL) and then copy the result to an Xwindow which is forwarded to a local machine. Sort of a RenderingDisplay=:0.0

<p class="MsoNormal">I think we need to be able to build an osmesa version of ParaView, and we need this rendering option as a command line option for all Kitware Linux downloads. The reason is that
the next version of Redhat – RHEL 7 will no longer allow the forwarding of GLX contexts. Thus, to be able to X forward ParaView back to a local computer, we will need to render into only an X window. This is already giving us issues at Sandia with new Linux
installs.<u></u><u></u></p>
