I cant tell which profile you have selected exactly. But from the available ones the preferred is
video-hybrid-intel-nvidia-440xx-prime
With that installed do
prime-run inxi -G
See how that works? … ex:
glxinfo | grep 'renderer string'
prime-run glxinfo | grep 'renderer string'
Thats the long and short of it … for more see here:
