Hi piorunz,

Thanks for your interest! I really appreciate your time. Background: 
I've been using Debian since Potato. This distro Just Works.

There are no errors. Only warnings about an unsupported Wifi chip (r8169 
missing RTL8125b-2).

As an aside: I have not mentioned this before, and I think it is a red 
herring: The problems started when I connected the wifi antenna to the 
board. The firmware for this chip isn't supported in this kernel, yet. I 
think I can download the drivers from Intel. I'm not really interested 
in wifi for this machine, as a wired connection works for now. This is 
too coincidental and unrealistic, but I want to get past it so we can 
move to other things. As soon as the antenna connections (dual coax) to 
the board were made, the screen went black. I know. Bullshit. The board 
doesn't really need an external antenna to detect wifi, so the antenna 
connection only boosted the signal. If the OS wanted to load a 
non-existent driver (which it's already trying to do as that failing 
attempt appears in boot.log), it would've tried before then, external 
antenna or no. Then somehow botch already loaded amdgpu firmeare? I 
don't think so. It's as coincidental as the bookworm updates earlier 
that day. When I rebooted to clear the issue (Linux isn't windows! One 
doesn't reboot to fix issues), no display...

Anyway, on to your other questions...

There are no logs. nomodeset doesn't log anything. It enables display 
twitching during boot. When XDM gains control, it will try to set the 
display mode.

I don't have inxi installed. I will install it and post the results.

For me, nada. One of my earliest tests. I swear, I did see positive 
results earlier!

I'm sure it's integrated. It's a Asus board model B550M-A By now, it has 
"reasonable" kernel support. About 18 months ago, it did not have such 
support. As I said earlier, I think wifi isn't well supported, but I 
don't care right now.

It's based on intuition. If I had the resources to follow up that hunch, 
I would. I don't know where to start with such suppositions; which are 
based on instructions like "cat BLAH > /FOO/BLECH" to change OS behavior.
