I getting the following error when running paraview on a cluster environment using vnc.
[VGL] ERROR: in glXGetConfig–
[VGL] 1124: Could not obtain RGB visual on the server suitable for off-screen rendering
I already checked the xservers are running on the nodes. Is there anything I could do to debug this problem?
vnc does not support opengl by default.
Options to fix this include
turbovnc + virtualgl
The free version takes control of the server screen, so you’ll have to be the only person using that server. I think there is a paid version that works like vnc.
using a headless display such as EGL or OSMesa on the server and connect using ParaView Client running on your client machine
