$ nvidia-smi
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 currently have the base ubuntu nvidia driver installed. (nvidia-driver-460(proprietary))
I also installed cuda-toolkit from apt.
I go into setting and go to "about" my graphics card is listed as:
llvmpipe (LLVM 11.0.0, 256 bits)
$ prime select query
nvidia
However running nvidia-settings returns this
nvidia-settings
ERROR: NVIDIA driver is not loaded
ERROR: Unable to load info from any available system
I have purged all nvidia several times and tried installing drivers manually and that has failed also.
I have also disabled safeboot.
