Is it possibile to use VirtualGL/TurboVNC on Raspberry Pi? Remote Raspberry Pi 3D graphic using VirtualGL/TurboVNC? Up vote 7 down vote favorite. I eventually managed to do it using dispmanx_vncserver on the Pi and connecting to it with TurboVNC from a Mac.

My first thought was to updade to the latest version of VirtualGL (VirtualGL-2.5.2.x8664.rpm) but this resulted in the same error message above. Would anyone have any thoughts or suggestions about how to address and fix this phenomena? Thank you, Jim DRC 20/6/2018, 12:19 น. The Foundry is a TurboVNC sponsor, so I would pursue this through their support channels. If they can reproduce it, then they can engage me through our existing contractual relationship in order to fix it. The use of a Mac as a client platform is irrelevant unless you are using the VGL Transport (vglconnect.) And if you are using the VGL Transport, then I would suggest not doing that.
Use TurboVNC, which is the 2D X server that The Foundry has tested with their application (more specifically, TurboVNC 2.2 beta.)

NX is kind of a hybrid X proxy, in that it technically runs an X server on both the server and the client, with heavy protocol compression in between. So if the failure is specific to Mac clients, and it works properly with other clients, then the proximate cause is likely to be an NX issue. However, this: /INFO: Graphics card floating point support not found; Viewer hardware accelerated effects disabled. Is suspicious. I don't know exactly what 'Graphics card floating point support' is, but if that's referring to floating point GLX FB configs, then it may be that: - For reasons unknown, VGL is somehow not handling a GLX/OpenGL feature that the application needs, and - This is somehow causing the application to fall back to a non-OpenGL method of rendering, and - Perhaps the fallback method of rendering is relying on an X extension that is missing or broken in the Mac implementation of the NX client.
In that case, the proximate cause may be NX, but it still may be possible to work around the issue in VGL. I definitely think that pursuing the matter with The Foundry is the best thing to do for now. If they can point to the underlying reason why the 'Graphics card floating point support not found' error would occur, and if they can explain how the application behaves differently when that error occurs, then perhaps it will reveal more about how to work around the problem. - You received this message because you are subscribed to the Google Groups 'VirtualGL User Discussion/Support' group.
