Please help problem with amd external gpu, xserver doesn't load

i have a razer core x with rx 5700 xt inside

when i reboot the machine with the egpu connected via thunderbolt port, it doesn’t load xserver, there is no graphical login screen, sddm not running. I can still log in on the console just fine.

And if i plug out the thunderbolt port, xserver starts ok, everything is ok.

I put these in my configuration.nix

 boot = {
    kernelParams = [ "udev.log_level=3" ];
    initrd = {
      kernelModules = [ "amdgpu" ];
    };
  };
  services.xserver = {
    enable = true;
    videoDrivers = [ "amdgpu" ];
  };
  services.hardware.bolt.enable = true;
  hardware = {
    opengl = {
      enable = true;
      package = pkgs.mesa.drivers;
      driSupport = true;
      driSupport32Bit = true;
      package32 = pkgs.pkgsi686Linux.mesa.drivers;
    };
  };

output of lscpi -k recognizes that i have the amd card, with the correct kernel module

06:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Navi 10 [Radeon RX 5600 OEM/5600 XT / 5700/5700 XT] (rev c1)
	Subsystem: Gigabyte Technology Co., Ltd Radeon RX 5700 XT Gaming OC
	Kernel driver in use: amdgpu
	Kernel modules: amdgpu

Try journalctl --list-boots and read the boot log when it doesn’t properly launch xserver it’ll most likely offer some clues as to why xserver is having trouble.

some log lines that might be useful, full on pastebin

Never seen it but it errors on what’s encountered here, no? https://www.linuxquestions.org/questions/slackware-14/xorg-doesn’t-start-after-mesa-19-1-1-update-no-unwind-info-found-error-4175656401/ strange that it all works if you plug it back in

I found a config that works, the problem is, since it creates a new xorg.conf and use it instead of the nixos-generated one, no keyboard or mouse is usable, all the other services.xserver configs in my configuration is meaningless

The said config: The Struggle to get Thunderbolt eGPU to output to its display at all in NixOS

ah, glad you got it figured out…and thanks for helping me learn about eGPUs! :slight_smile:

in the process, i noticed that xrandr --listproviders does not give me a provider, which is really weird since my igpu works, there’s output to screen just fine.

and I’m still struggling with the egpu since, in the thread i mentioned, they have successfully got the gpu running and output, but not mouse or keyboard.

my igpu is 00:02.0 VGA compatible controller: Intel Corporation Alder Lake-P GT2 [Iris Xe Graphics] (rev 0c)

xrandr --listproviders                                                                                                                                                                                           
Providers: number : 0

I think the reason why xrandr --listproviders gives me no provider is because I’m using hyprland.

This is my alternative approach, however, I was not successful. I booted up with this config fine, but it stop when it suppose to show SDDM log in screen.

It shows a black screen instead.

But other than that, there is no crash, xserver loaded fine (i guess?).

Here’s the config:
I use Radeon RX 5700 XT as my egpu, and hyprland

  services.hardware.bolt.enable = true;
  boot = {
    # Ensure module for external graphics is loaded

Please help me I have no idea what to do now…

What i want is the egpu is used when i plug it in, and igpu when i’m not plug in my egpu. That’s why i added

serverLayoutSection = ''
      Screen "Screen-amdgpu"
'';

This adds Screen "Screen-amdgpu" which i will define later on with config = lib.mkAfter '' at the very first of Section "ServerLayout"

since X server is (I’m guessing) going to try each in turn?

Am i doing this correct?

does it work? I can’t speak to the correctness as I don’t have your setup. But it looks OK to me

also are you using xwayland or whatnot? what’s xserver doing when wayland is involved?

It shows a black screen where it is suppose to be SDDM log in screen. It’s like there is no output at all.
I think xserver works but it doesnt seem to output to my screen.

I don’t know how to check this

I have xwayland enable, if my understanding is correct then

programs.hyprland = {
      enable = true;
      xwayland.enable = true;
      package = inputs.hyprland.packages.${pkgs.system}.hyprland;
    };

Sorry, I can’t help here. xorg configs beyond the simple always confused me when they didn’t work. At least there are no overt errors so maybe it’ll be simple in the end

at this point I’m desperate for any solution that you might have. I’m willing to test them all

Full log : pastebin
a thing that i noticed is that

[    72.435] (II) AMDGPU(0): [DRI2]   DRI driver: radeonsi
[    72.435] (II) AMDGPU(0): [DRI2]   VDPAU driver: radeonsi

but later it changed to

[    72.523] (II) modeset(1): [DRI2]   DRI driver: iris
[    72.523] (II) modeset(1): [DRI2]   VDPAU driver: va_gl

Is it perhaps using both AMDGPU and modesetting? or was I misunderstood it?

Is that a good sign or a bad sign? I honestly don’t know

[    72.440] (WW) AMDGPU(0): Option "AllowExternalGpus" is not used
[    72.440] (WW) AMDGPU(0): Option "AllowEmptyInitialConfiguration" is not used

And the AllowExternalGpus option is also not used

Although according to arch wiki, it is required for proprietary NVIDIA driver, but I’m using AMD so i guess that’s fine?

and this

/dev/dri/card1 is my AMD gpu, so why is it using modesetting
And I don’t see any log that AMDGPU uses /dev/dri/card1 too

I’m lost
