Paraview error VGL

ParaView Support
1

Hello,

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?

Thank you.

vnc does not support opengl by default.

Options to fix this include

  1. turbovnc + virtualgl
    https://virtualgl.org/vgldoc/2_1_1/

  2. nomachine
    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.

  3. using a headless display such as EGL or OSMesa on the server and connect using ParaView Client running on your client machine
