I don’t understand your comment of “don’t even know where these icons are?”
How do you launch apps on your system. Most users with a desktop gui use the icons regularly to launch the apps they use. The icons I spoke of are those same icons.
The icons used to lauch installed apps are available with the ‘Super’ AKA ‘Windows’ key or with ‘Super+A’ while in the gui desktop.
This can be done by first following the instructions at [Fedora Docs] (How to Set Nvidia as Primary GPU on Optimus-based Laptops :: Fedora Docs) to set the machine to always use the nvidia gpu as primary. Then reboot and during login select the ‘gnome on xorg’ option with the gear at the lower right of the screen where you enter the password.
Since you already have the nvidia drivers loaded and functioning you can skip to step 8 and start from that point.
The nvidia GPU is not used by default since it is a laptop and the iGPU uses less power so the dGPU is left idle until the user decides it should be used.
Since most users wish the gui desktop environment very few even use a cli environment.
Do you boot with the desktop then use a terminal or do you immediately log into a cli environment with ctrl+alt+F3 or similar? It does make a difference in what is available.
If you only use the cli environment the nvidia can still be made primary, then log into the gui desktop.
Once there the ctrl+alt+F3 will still get you to the cli login but this time the nvidia gpu would be primary and used for all display on the screen.
