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

    Device initalization failed according to the Xorg logs;

    1. Dump your firmware version
    2. Dump your kernel version
    3. Dump your kernel logs (dmesg or journalctl -k)

      Additionally you can try and force use amdgpu rather than radeon, by setting the kernel flags:

      radeon.cik_support=0 radeon.si_support=0 amdgpu.cik_support=1 amdgpu.si_support=1 amdgpu.dc=1
