Thank you George.
Ok. So this tells me I should probably not play around a lot with this because
it is not fully supported anyway.

Running this command is only listed my integrated graphics card:
00:02.0 VGA compatible controller: Intel Corporation HD Graphics 530 (rev 06)
DeviceName: Onboard IGD
Subsystem: Dell XPS 15 9550
Kernel driver in use: i915
Kernel modules: i915

Does the Nouveau driver come preinstalled in F33 ? I can see that the
xorg-x11-drv-nouveau package is installed.
I can see that there are some messages related to nouveau at startup (some
regarding FAULTs).

So I will ask the previous question again. Does this driver come preinstalled?
Or do I need to activate these Third Party Repositories offered by the Gnome
Software app (rpmfusion-nonfree-nvidia-driver.repo)?
Once I activate this repository, do I need to install a specific package for my
graphics card?

I dont understand how this answers my question. Reading the PRIME article just
tells me that it is up to me whether I want to use the proprietary or the open
source drivers. I think this is way above my level of understanding. As I said
before, this is the first time I own a laptop with a discrete graphics card.
Thanks very much.
