I tried to use https://github.com/guibou/nixGL/blob/4de92f0/README.md#opengl---hybrid-intel--nvidia-laptop but (https://github.com/guibou/nixGL/tree/489d6b095ab9d289fe11af0219a9ff00fe87c7c5):

Is it due to cat /proc/driver/nvidia/version not found (see https://discourse.nixos.org/t/nixgl-needs-you-for-testing/6921/15) ?

For the nixGLNvidiaBumblebee wrapper to work one needs to have the drivers installed on their system first, just a very tiny selection of examples for a laptop with hybrid graphics, more to find in the README:

For other hardware scenarios sudo lshw -c display might help.
