From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

omg i've been in this rabbit hole trying to get a friend's laptop working right for the last 2 weeks... I found the name of the thing you are talking about, where the dGPU HAS to talk to the integrated graphics to get to the laptop screen... and then promptly forgot it after getting so mad at such a stupid idea and when I went to google it again to find articles i had previously read I couldn't find it. :(
I decided to take a look and I think it's called Nvidia Optimus. A more general term would be hybrid graphics I guess.
And I think I may have come across the Bumblebee project back then: https://github.com/Bumblebee-Project
Maybe this helps.
