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.

Linux does not do GPU switching the same way Windows does, if that's what you're asking. You won't be able to just dynamically switch between video adapters.
As far as the quality of the AMD APU chips, totally fine. They are the best on the market, obviously. I have a Ryzen 7000 series with a 680M, and it "just works", as well as playing every title I've ever thrown at it totally smoothly.
Hmm... are you sure about that?
DRI_PRIME=1switches to the discrete GPU (or used to at least - I don't have hybrid graphics anymore). I'd be surprised if that feature were removed...CC BY-NC-SA 4.0
This is render offloading, not GPU switching. GPU switching implies switching the primary rendering device (the one power the displays) entirely rather than rendering on a separate GPU and copying the output to the primary.
Most gaming laptops these days don't support true GPU switching as it requires a hardware mux to switch the display between the GPUs. Every gaming laptop I've used from the past decade has been muxless and only used render offloading.
I see! Thanks for clearing that up.
