No output found Xrandr Hybrid setup

Hi everyone,
I have a laptop with an AMD HD8750M and an integrated Intel video card.
I was trying to configure outputs to have an hybrid setup, as described in the wiki (https://wiki.archlinux.org/index.php/PRIME), but when I type

 xrandr --listproviders

I get:

Providers: number : 2
Provider 0: id: 0x6a cap: 0xb, Source Output, Sink Output, Sink Offload crtcs: 4 outputs: 5 associated providers: 1 name:Intel
Provider 1: id: 0x41 cap: 0xf, Source Output, Sink Output, Source Offload, Sink Offload crtcs: 2 outputs: 0 associated providers: 1 name:OLAND @ pci:0000:03:00.0

I don't know how to solve the fact that it says there are no outputs available on the radeon card. I have both installed amdgpu and radeon. Using amdgpu only I get the same output but the name of Provder 1, which is modesetting.
I would like to configure it properly to get a decent output from the discrete card.

Thank you very much

"Outputs" means "slots to plug in a monitor" - there's none wired to that GPU, all output will be redirected through the intel chip in order for your to see something.
There's nothing you can do or should worry about this.

Thanks, so how should I set the reverse/non reverse prime configuration?

The Wiki wrote:

If the second GPU has outputs that are not accessible by the primary GPU, you can use Reverse PRIME to make use of them. This will involve using the primary GPU to render the images, and then pass them off to the secondary GPU.

Think about it…
