Good news. This resolved my issue. I could not run “sudo ubuntu-drivers install” as it complained about broken packages. However, I already had the drivers installed (NVIDIA-SMI 515.65.01 Driver Version: 515.65.01 CUDA Version: 11.7 ) and I went ahead with the test. It worked.
Here is the output for “glxinfo | grep OpenGL”. So, it seems the “prime-select nvidia” solved the issue for me.
