I have Aero 15x v8 with nVidia 1070 and intel integrated graphics. I have gone to "additional drivers" and selected proprietary nvidia-driver-390. I applied the changes and re-booted.
when I terminal > prime-select query, I get "nvidia" however, settings>details: shows graphics "Intel HD Graphics"
Which is actually being used ?? How do I make sure I'm using Intel graphics for battery savings but then switch to nvidia for games ?
also, The nvidia-settings app does not show any option for PRIME profiles
