Searching a bit, it looks like some folks are having success with the Radeon 5700 (XT) and Fedora 32.
Not me. :-/
I first posted on ask.fedoraproject.org; and while I was able to drill down and get a bit more information, responses there seem to have tapered off.
A few data points:
$ lspci -k | grep -EA3 'VGA|3D|Display' 09:00.0 **VGA** compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Navi 10 [Radeon RX 5600 OEM/5600 XT / 5700/5700 XT] (rev c1) Subsystem: Advanced Micro Devices, Inc. [AMD/ATI] Device 0b36 Kernel modules: amdgpu 09:00.1 Audio device: Advanced Micro Devices, Inc. [AMD/ATI] Navi 10 HDMI Audio
While that checks out, for some reason amdgpu isn’t listed in the lsmod output:
$ sudo lsmod | grep amd edac_mce_amd 32768 0 kvm_amd 114688 0 kvm 806912 1 kvm_amd ccp 102400 1 kvm_amd amd_iommu_v2 20480 0 pinctrl_amd 32768 0
I don’t get Wayland when I log in; I get the X11 fallback. Looking at the Xorg log, it never even tries the amdgpu driver. It tries the radeon driver; and when that fails, I get the generic framebuffer fallback.
Any suggestions for next steps to take?
