X.org: no screens found

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: pastebin.com/7tsvGA7rOS: Debian 12

Well, for starters, unless you’re running a quite old card you should be using amdgpu, not radeon. You seem to have them both loaded.

Post a dmesg?

Driver isn’t loaded.

Firmware is not a driver.

Kernel driver is loaded
