Unable to build nix due to nvidia drivers due or kernel 6.10(?)

[nPrevail]

I also saw your post on this earlier this morning, and it worked:

Builder for nvidia-x11-550.78-6.10.drv failed with exit code 2

Appreciate the sentiment, hopefully amd/intel release a less humongous/power hungry model at some point… Modesetting is mandatory for wayland. The powermanagement setting is required to support sleep. Otherwise this looks correct. For the record, what is the exact set of problems (including whether nvidia-settings works) you get after a nixos-rebuild boot --use-remote-sudo && systemctl reboot with: # fuck nvidia services.xserver.videoDrivers = ["nvidia"]; hardware.nv…

So, I guess “specific nvidia driver version” is the way to go until the update nvidia stable to 555.0+

How did you find this solution?

I would just maintain the driver version downstream at least until the LTS kernel catches up with your hardware, personally.

@nPrevail

It was pretty obvious after the fourth time the latest kernel was incompatible with the current nvidia driver version on stable. I think I first started running a different nvidia version in 2022?

Using mkDriver to do this became possible towards the end of last year, I learned about it from one of the nvidia maintainers after I explained to someone here how to do this and they pointed out there’s a nicer way now.

I use xanmod not stable, zen or latest, over 6.10 its not work with error
also i see 550.78 won't compile on 6.10-rc1 due to GPL violations and removed follow_pfn() - #6 by SoftExpert - Linux - NVIDIA Developer Forums
maybe it can solve by using patch

[TLATER]

Just update the driver to a version that supports 6.10, 550.78 is ancient by nvidia driver standards: Unable to build nix due to nvidia drivers due or kernel 6.10(?) - #18 by TLATER

Perhaps this would be my learning lesson about ‘mkDriver’: Since 560.35.03 released a few hours ago, how would one go about with inputting the following? Where can I find the following information, or find out if it’s available for NixOS?

version = 
  sha256_64bit = 
  sha256_aarch64 = 
  openSha256 =
  settingsSha256 =
  persistencedSha256 =

As @TLATER said before, you can either set these to an empty string, rebuild and it will give you the values, but you can also get this information directly from the PR: linuxPackages.nvidiaPackages.latest: 555.58.02 -> 560.35.03 by Kiskae · Pull Request #336334 · NixOS/nixpkgs · GitHub

Generally, you can get the hashes for all versions (stable, beta, …) from the nvidia-x11 package.

Ah, you’re right… I actually didn’t understand what an “empty string” is, but I’ll try to look it up. I don’t want to bother folks any further, but I appreciate everyone’s input!

[TLATER]

Like this:

hardware.nvidia.package = config.boot.kernelPackages.nvidiaPackages.mkDriver {
  version = "560.35.03";
  sha256_64bit = "";
  sha256_aarch64 = "";
  openSha256 = "";
  settingsSha256 = "";
  persistencedSha256 = "";
};

"" is a string of zero characters, i.e., an empty string.

You can also use lib.fakeHash, but that’s unnecessary here.

[sepal]

Any idea what values work for 560 ? I managed to use @TLATER 's config for version 555 above, but could not get 560 to work

[TLATER]

Nor have I: nvidia: Update to 560.35.03 by TLATER · Pull Request #360 · TLATER/dotfiles · GitHub

The build dependencies changed, AIUI, so the update is less trivial now. I still need to sit down and figure it out sometime.

[eljamm]

Couldn’t help but notice that some hashes are different from the ones in nixpkgs (which work fine for me).

$ diff nixpkgs.txt tlater.txt
3c3
< sha256_aarch64 = "sha256-s8ZAVKvRNXpjxRYqM3E5oss5FdqW+tv1qQC2pDjfG+s=";
---
> sha256_aarch64 = "sha256-8pMskvrdQ8WyNBvkU/xPc/CtcYXCa7ekP73oGuKfH+M=";
6c6
< persistencedSha256 = "sha256-E2J2wYYyRu7Kc3MMZz/8ZIemcZg68rkzvqEwFAL3fFs=";
---
> persistencedSha256 = "sha256-VWTJg/pluRYVVBDiJ+t2uhyodRuIFfHpzCZMte1krDM=";

Could this be the problem?

[TLATER]

Hmm, that should result in the download failing, not a build failure. I’ll have to check what’s up.

[TLATER]

Do you disable nvidiaSettings? This commit is required to get that driver version to build on stable: nvidia-settings: add vulkan-headers dependency · NixOS/nixpkgs@0384602 · GitHub

[eljamm]

@TLATER

Do you disable nvidiaSettings?

No, I’ve always had it enabled.

@TLATER

This commit is required to get that driver version to build on stable: nvidia-settings: add vulkan-headers dependency · NixOS/nixpkgs@0384602 · GitHub

I’m using nixos-unstable, so that commit was already included in my nixpkgs by the time I updated.

Hi folks,

Same situation as last time, but now with kernel 6.14 :

Unable to build nix due to nvidia drivers due or kernel 6.10(?)

I ran sudo nixos-rebuild switch --upgrade, and I think my nvidia drivers or kernel 6.10 have conflicts building in my system: /build/NVIDIA-Linux-x86_64-550.78/kernel/common/inc/nv-linux.h: In function 'nv_ioremap_cache': /build/NVIDIA-Linux-x86_64-550.78/kernel/common/inc/nv-linux.h:531:33: warning: suggest braces around empty body in an 'if' statement [8;;https://gcc.gnu.org/onlinedocs/gcc/Warning-Options.html#index-Wempty-body-Wempty-body8;;] 531 | NV_MEMDBG_ADD(ptr, size); |…

I’ve tried using an “empty string” but it also doesn’t work for me, such as: Unable to build nix due to nvidia drivers due or kernel 6.10(?) - #28 by TLATER

How do folks normally get all the information for:

hardware.nvidia.package = config.boot.kernelPackages.nvidiaPackages.mkDriver {
  version = "560.35.03";
  sha256_64bit = "";
  sha256_aarch64 = "";
  openSha256 = "";
  settingsSha256 = "";
  persistencedSha256 = "";
};

Is there a specific website I should turn to find the sha256 and etc.?

I’m seeking the latest nvidia drivers for NixOS that would allow me to upgrade the kernel to 6.14.

@nPrevail

Nix hashes use a nonstandard alphabet, computed over the full directory tree in a special archive. In theory you can calculate them, have fun if you insist.

nix-prefetch-* scripts exist, but it’s a PITA to figure out what you’re supposed to download, especially for the nvidia driver since it’s 4 different URLs in a clown car. I think the extraction mechanism for at least some of them is custom, too, so you’d have to match that perfectly.

@nPrevail

’ve tried using an “empty string” but it also doesn’t work for me, such as:

What exactly do you mean by “doesn’t work for me”? Like, does nix segfault, or are you unable to read the strings it prints? Does replacing the empty strings with lib.fakeHash help?

[nPrevail]

@TLATER

Does replacing the empty strings with lib.fakeHash help?

What exactly do you mean by “doesn’t work for me”?

My apologies for the vague conclusion.

I actually get the same output whether I use empty strings or lib.fakeHash or lib.fakeSha256 in either scenario:

[drakon]

So in that case, the value of settingsSha256 is sha256-XMk+FvTlGpMquM8aE8kgYK2PIEszUZD2+Zmj2OpYrzU=. The derivation name is similar enough to the attribute name and the hash is what appears in the error, so you should be able to find out the rest by updating the values until it works.

[nPrevail]

@drakon

the value of settingsSha256 is sha256-XMk+FvTlGpMquM8aE8kgYK2PIEszUZD2+Zmj2OpYrzU=

Just curious, how did you know this value was for settingsSha256, and not the other entries? What was the indication?

[waffle8946]

@nPrevail

I actually get the same output whether I use empty strings or lib.fakeHash or lib.fakeSha256 in either scenario:

Yes, that is the expected output here. It’s definitely confusing to have a bunch of derivations called source but as @drakon pointed out, you can likely guess what hash it’s talking about based on what depends on it.

@nPrevail

What was the indication?
