What happens if you run "modprobe amdgpu"?
This:
# modprobe amdgpu
modprobe: ERROR: could not insert 'amdgpu': Invalid argument
What is the output of "cat /proc/cmdline"?
This:
# cat /proc/cmdline
BOOT_IMAGE=(hd1,gpt2)/vmlinuz-5.7.6-201.fc32.x86_64
root=UUID=cbcfb536-a8c8-4f79-8efd-60bec46d8a39 ro

Look through the logs starting from boot to see if anything is
happening with the amd driver. "journalctl -b"
Searching through that for “amd”:
Jul 02 02:25:33 mull kernel: amd_uncore: AMD NB counters detected
Jul 02 02:25:33 mull kernel: amd_uncore: AMD LLC counters detected
This looks suspicious:
Jul 02 02:25:34 mull kernel: [drm:amdgpu_init [amdgpu]] *ERROR* VGACON disables amdgpu
kernel modesetting.
Same thing a few seconds later:
Jul 02 02:25:39 mull kernel: [drm:amdgpu_init [amdgpu]] *ERROR* VGACON disables amdgpu
kernel modesetting.
There is no amdgpu X driver. It's either radeon or modesetting.
Ah.
