Ok, first of all thanks for the prompt reply, but there is a lot I don't
understand. I just got into linux in these past 2 months. So please bear
If the dGPU has no display attached to it then how is it expected to
function ? I mean on my desktop I have VGA connected directly to 650 GTX.
How does it work over here ?

Is the DRI_PRIME set when I select "Launch using dedicated Graphics
card" in Gnome ?

I want all operations to be from the dGPU. You know, my expectation is
something like that of my desktop I mentioned above. I don't know if
that is possible.
If not, I would like to understand why it is not possible.
