--- Comment #2 from Jonathan Vasquez <jon@xyinn.org> ---
Hey Emmanuel,

I tested the APU just now on Fedora 37 and it works perfectly fine (even on
Wayland). I've attached the linux lspci, dmesg, and uname info, and also two
screenshots of GNOME fully running on it.

We can see the following information from the lspci output for the gpu
components (first is the dedicated 6900 XT card, second is the integrated
raphael gpu):

I've also attached a crash dump that only occurs if I try to start sddm while
the HDMI cable is connected and outputting to the motherboard's HDMI slot (the
raphael gpu), if I switch the HDMI cable to the dedicated card, it doesn't
crash. I'm guessing this is because it's not supported yet so it may expected
behavior in this current state.
