My latest adventures in AMD drivers:
I tried the kernel 5.4.0 from the backports under beowulf. I forced the
backports version upgrade for firmware-amd-graphics; there was no backports
version of xserver-xorg-video-amdgpu. It worked, and seemed to perhaps flash a
little less than previously. It loaded kernel modules amdgpu and radeon, and
used radeon for the X server driver. I shut down slim, and tried Xorg
--configure which called for the amdgpu driver, as expected. Starting the
server with the amdgpu xorg.conf failed with the usual message about 2.50.0
being incompatible with 3.x.x, which is a radeon/amdgpu incompatibility, I
believe.
I blacklisted radeon, and rebooted, and indeed only the amdgpu module was
loaded.
Trying to run the X server with amdgpu I got another fatal message (which I have
seen before):
[ 34.842] (II) AMDGPU: Driver for AMD Radeon:
All GPUs supported by the amdgpu kernel driver
[ 34.842] (II) AMDGPU(0): [KMS] drm report modesetting isn't supported.
[ 34.842] (II) AMDGPU(1): [KMS] drm report modesetting isn't supported.
I don't have any trouble loading the amdgpu driver, it just doesn't work! I
believe lsmod when it says that only amdgpu is loaded! Trying to track down
that specific error message on the web usually just leads you to "upgrade your
driver" solutions.
I'm pretty sure that the AMD proprietary driver will complain about my kernel
version, but after Roland's report, I am very doubtful that it would make any
difference. Like Roland, I'm more interested in resolution and stability than
speed. I do have a couple of 4K monitors but only one is in use right now on
this system.
Thanks for all the help! [If I had to run a systemd-based distribution to
make this thing work I'd definitely toss it in the trash immediately ;) ] Most
likely outcome is I try to send this thing back to Amazon. If that fails, a
blistering review will probably follow ;)

Ahmad, of course, I did.
