Copying Custom EDID

It is possible the final error log you are getting is unrelated to the custom EDID. On recent versions of nixpkgs-unstable both my 5000 and 6000 series AMD GPU’s are failing with the exact same errors in the log. I have been unable to find a workaround so far.

That might be it. I’m using a 6XXX GPU on the system with the EDID not loading properly, but the working system is using a Vega series GPU.

My “workaround” is to turn the TV on/off after logging in. I also need to switch resolutions back and forth, but that’s due to quirks of the DP → HDMI adapter.

I have been trying to figure this out, but gotten nowhere.

  • drm.edid_firmware=edid/MSI-1462.bin is set.
  • File /nix/store/<hash>-firmware/lib/firmware/edid/MSI-1462.bin.xz exists.
  • Running unxz -dc /nix/store/<hash>-firmware/lib/firmware/edid/MSI-1462.bin.xz > /sys/kernel/debug/dri/0/DP-2/edid_override applies correctly.

But rebooting will throw the following to the journal.

Jan 09 04:58:25 desktop kernel: amdgpu 0000:03:00.0: Direct firmware load for edid/MSI-1462.bin failed with error -2
Jan 09 04:58:25 desktop kernel: amdgpu 0000:03:00.0: [drm] *ERROR* [CONNECTOR:121:DP-2] Requesting EDID firmware "edid/MSI-1462.bin" failed (err=-2)

I am quite lost for what to do next. I checked quickly in drm / amd · GitLab for similar issues, but found none. I also have a RX 6xxx GPU. But this seemingly being entirely localized to NixOS makes me unsure if its an upstream problem. I guess it would require someone to test on Arch or a similar distribution to verify.

Created an issue here: amdgpu: cannot set modified EDID binaries. "Requesting EDID firmware ... failed (err=-2)" · Issue #279739 · NixOS/nixpkgs · GitHub

Thanks ! You saved me quite some time here !

In my case, like in arch, I added an extra kernel parameter for it to work. To be honest, I don’t remember why the output needs to be forced.

"video=DP-2:e"

That may help others having trouble with this.

My relevant specs are:

  • On DP-2 : Asus PG278Q - limited to 120Hz (even if it’s a 144Hz - I never managed to get it to 144 on linux
  • 6900XT
  • systemd-boot

The full piece of code for it :

{
  boot.kernelParams = [ "drm.edid_firmware=DP-2:edid/edid.bin" "video=DP-2:e" ];
  hardware.firmware = [
  (
    pkgs.runCommand "edid.bin" { } ''
      mkdir -p $out/lib/firmware/edid
      cp ${../custom-files/edid/edid.bin} $out/lib/firmware/edid/edid.bin
    ''
  )];
}

something changed with newer nixpkgs versions since around a week, the edid parameter only seems to work with chaotic nyx cachyos kernel currently, but not anymore with “latest”, “xanmod” or “lqx”(even tho all are same mainline version number)

i tried it both with xz and uncompressed using

im currently on nixpkgs version of around staging-next 2024-03-24 by vcunat · Pull Request #298548 · NixOS/nixpkgs · GitHub
+ the edid pr + unrelated zitadel version bumps

anyone got a clue?
seems to have happend between nixpkgs Merge pull request #276816 from majiru/nixos-tests-build-discrepancy · NixOS/nixpkgs@ca0de94 · GitHub and

I have just implemented a post-boot systemd service as a fallback nixos/hardware.display: init module by nazarewk · Pull Request #279789 · NixOS/nixpkgs · GitHub as part of nixos/hardware.display: init module by nazarewk · Pull Request #279789 · NixOS/nixpkgs · GitHub for those cases. Using it right now with today’s nixos-unstable.

FYI: after today’s nixos-unstable update (bump from last week) my Asus PG278Q became completely invisible

seems like the kernel stopped handling video=DP-1:e commandline, see nixos/hardware.display: init module by nazarewk · Pull Request #279789 · NixOS/nixpkgs · GitHub

same monitor here with the (probably same) issue here: Copying Custom EDID - #26 by MisterOutofTime

for now im stuck on cachyos kernel from nyx (since that one still works)
