Changing the graphic card prevent X11 from launching

mtetreault · March 15, 2022, 2:34am

Hello,

I switched my nvidia graphic card to an amd graphic card in my nixos machine. Since then X11 is unable to start for some reason.

The new graphic card is an amd Radeon RX 6500XT

Here is the configuration that I added:

boot.initrd.kernelModules = [ "amdgpu" ];
services.xserver.enable = true;
services.xserver.videoDrivers = [ "amdgpu" ];
hardware.opengl.extraPackages = with pkgs; [
   rocm-opencl-icd
   rocm-opencl-runtime
   amdvlk
];
hardware.opengl.driSupport  = true;

The display manager use is lightdm and the desktopmanager is xfce.

Debugging that I did:

journalctl -u display-manager.service

systemd[1]: Started X11 Server.
systemd[1]: display-manager.service: Main process exited, code=exited, status=1/FAILURE

you seem to have all the important parts from AMD GPU - NixOS Wiki covered.
What do you get from running head /sys/class/drm/*/status ?
So you have any autogenerated X11 config left over from the NVIDIA card?
What channel are you running? 21.11 or unstable?

I suspect the interesting parts are here, but I don’t have enough experience with amdgpu to troubleshoot this kind of failure.

Most likely your kernel is too old. Support for 6000 series AMD cards was landed in linux 5.9. If you do uname -a and it’s younger, this is likely your issue.

For NixOS:

boot.kernelPackages = linuxPackages_5_15;

ius · March 15, 2022, 7:59am

He’s on 5.10 according to @mtetreault’s logs. The 6500XT card is a quite recent model in the 6000 series though, codename Beige Goby. So you’ll need a fair bit newer kernel/firmware.

According to this Phoronix aritlce it’s included since v5.14, so your suggestion should still work. Firmware landed somewhere around september, so that’s okay for NixOS 21.11 (which is on 20211216).

@jonringer @ius Thanks for your help, my kernel was indeed too old. I switched to the latest kernel and it works flawlessly.
