Hi all,  
Sorry to bother, but my Paraview is running extremely slow on my workstation (ubuntu 20.04), to the point where the software just goes unresponded and I have to force quit. I tried reinstalling it to the newest version but it didn’t work.  
Later I found in a similar post that the issue might have something to do with the OpenGL implementation (MESA vs. NVIDIA). I did the following check through googling. However, I still don’t know how to switch my OpenGL implementation from Mesa to NVIDIA.

```auto

NVIDIA-SMI has failed because it couldn't communicate with the NVIDIA driver. Make sure that the latest NVIDIA driver is installed and running.

I would greatly appreciate it if someone could help me with this. Thank you!
