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
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?
I have R9 280
That looks to be Volcanic Islands, which has good support with
amdgpu
and no support byradeon
, according to Wikipedia.I’m not sure what you meant by “set up radron kernel driver”, but you could maybe try blacklisting it.
