X.org: no screens found

user_naa@lemmy.world to Linux@lemmy.ml – 26 points –

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: https://pastebin.com/7tsvGA7r OS: Debian 12
