GPU Switching with prime-run vs. optimus-manager/optimus-manager-qt

The Nvidia driver seems to be not loaded.
Not being a Nvidia user/expert, two things come to my mind.

  1. Due to this

check if the ibt=off kernel boot parameter might help: see e.g. here how to do it.
2. If the above does not help, try a:

sudo dkms autoinstall

and in case of errors, check the mentioned logs.
