Installed using software update ->additional drivers ->using nvidia driver metapackage from driver-460 (prop,tested).

On nvidia x server settings i see prime profiles -> nvidia performance mode checked.

On settings-> about i see my integrated gpu not my nvidia graphics card.

If i run sudo nvidia-settings the output is ERROR: NVIDIA driver is not loaded

ERROR: Unable to load info from any available system
