Recenty I changed my old NVidia GPU with nouveau to AMD. I installed firmware-amd-graphics and set up radron kernel driver. But when I try to start X11 with default config (X -configure) it fails with no screen error. Kernel radeon driver works well and tty resolution is proper.
When I try run Debian live usb X.org works well.
Xorg.0.log:

OS: Debian 12
Screen 0 deleted because of no matching config section.
Your XOrg conf ig has got hard definitions of your devices which aren't matching what is being detected. Probably best to let auto detection do it's thing.
This happened to me by even though I had never hard configured anything… had to go to the config folder and find the offending definition and delete it

I have a computer where xserver not work if you try to use it together with the internal graphiccard. With Wayland even a Screen on this internal card works.
So I propose to try Wayland.
