AMD GPU not used by Fedora 31

[Sreyan Chakravarty <sreyan32@xxxxxxxxx>]

My laptop model is the HP-ac179tx.

Full Specs here: https://support.hp.com/in-en/document/c04919819

It has an AMD Radeon R5 M330 Graphics (2 GB DDR3 dedicated) GPU which is currently not being used by Wayland Gnome in Fedora.

This is the output of:

$ lspci | grep -i VGA

00:02.0 VGA compatible controller: Intel Corporation Skylake GT2 [HD Graphics 520] (rev 07)

As you can see it is operating on the in-built Intel Graphics. I want all display operations to happen through the AMD GPU, is that possible?

Now, I know video card drivers has always been a dicey topic, where there is no stable drivers, just softwares that fail a little less than other counterparts.

So, I have a few questions:

1) I am using Gnome-Wayland. Are there at all any video card drivers out there for Wayland ?

2) To use video drivers is it necessary to switch to XOrg ?

3) Is it possible to transfer all display operations to the GPU ? Like my desktop has the monitor connected to the GPU directly, which means all display is handled by the GPU. Is something similar possible here?

I did try installing the AMDGPU-Pro Driver from here:

https://www.amd.com/en/support/kb/release-notes/rn-radpro-lin-16-40

But it fails with the error:

No match for argument: amdgpu
Error: Unable to find a match: amdgpu

Also Fedora was even listed in page, so I guess that means that it is not supported.

Some relevant diagnostic information about my laptop:

$ sudo kmod list | grep amd
amdgpu               5308416  0
amd_iommu_v2           20480  1 amdgpu
gpu_sched              36864  1 amdgpu

$ sudo rpm -qa | grep vulkan | sort

mesa-libxatracker-19.2.8-1.fc31.x86_64
mesa-vulkan-drivers-19.2.8-1.fc31.x86_64

Lastly, I have LVM snapshotting enabled, so I should be able to try out things so long as they don't involve my /boot and /boot/efi directories as they are not included in the LVM.

Let me know what is the best course of action here.

Thanks.
