I have not been able to install nvidia drivers for months

Help
1

was hoping 23.05 would solve it, but no.

no package will compile, no matter version, open source, proprietary, vulkan beta. at the moment all seem to throw this same error:

/build/NVIDIA-Linux-x86_64-515.49.25/kernel/nvidia/nv-mmap.c:593:23: error: assignment of read-only member ‘vm_flags’

anyone else had this problem and/or know how to solve it?

thanks

Could you share some details about the procedure/setup/configuration you are using to install the drivers?

just basic stuff in configuration.nix. i’ve included <nixos-hardware/common/gpu/nvidia/prime.nix> and various combinations of:

services.xserver.videoDrivers = [ “intel” “nvidia” ];
hardware.nvidia.package = config.boot.kernelPackages.nvidiaPackages.vulkan_beta;
#hardware.nvidia.package = config.boot.kernelPackages.nvidiaPackages.production;
#hardware.nvidia.package = config.boot.kernelPackages.nvidiaPackages.latest;
#hardware.nvidia.package = config.boot.kernelPackages.nvidiaPackages.legacy_470;
#hardware.nvidia.package = config.boot.kernelPackages.nvidiaPackages.legacy_340;
hardware.nvidia.open = false;

(it’s a laptop with integrated intel and discreet nvidia gpus)

i’m not a sophisticated nixos user. it’s a pretty basic setup. i’ve just upgraded to 23.05, but i’ve been getting errors long before also on 22.11

here’s when i try the legacy 470 version:

/build/NVIDIA-Linux-x86_64-470.161.03/kernel/nvidia/nv-acpi.c:84:19: error: initialization of ‘void (*)(struct acpi_device )’ from incompatible pointer type 'int ()(struct acpi_device *, int)’ [8;;Warning Options (Using the GNU Compiler Collection (GCC))]
84 | .remove = nv_acpi_remove_two_args,

and then again, a bunch of errors like this:

/build/NVIDIA-Linux-x86_64-470.161.03/kernel/nvidia/nv-mmap.c:599:23: error: assignment of read-only member ‘vm_flags’
599 | vma->vm_flags |= VM_IO | VM_PFNMAP | VM_DONTEXPAND;

Could you try with services.xserver.videoDrivers = [ "intel" "nvidia" ]; alone, without the include or any other related setting?

solene, thank you for your replies.

i’ve done what you suggested. here is the result, much the same:

/build/NVIDIA-Linux-x86_64-520.56.06/kernel/nvidia/nv-mmap.c: In function ‘nvidia_mmap_numa’:
/build/NVIDIA-Linux-x86_64-520.56.06/kernel/nvidia/nv-mmap.c:446:19: error: assignment of read-only member ‘vm_flags’

580 | vma->vm_flags |= VM_IO | VM_PFNMAP | VM_DONTEXPAND;

…and several more vm_flags errors.

the c90 warning made me think it could be a c standard thing, though i’m not a c programmer and anyway i don’t know how to get nix to adjust the compiler flags

i started out with just services.xserver.videoDrivers = [ "intel" "nvidia" ]; and only started trying the other stuff when the compile began to error out.

Are you using latest linux kernel? It seems nvidia drivers with 6.3 have some issues https://forums.developer.nvidia.com/t/driver-470-182-03-fails-to-compile-with-linux-6-3-1/251992/2

You’re not actually running nixos-23.05. You’re building version 520.56.06 of the nvidia driver, but nixos-23.05 was released with version 530.41.03. If I build with nixos-22.11, it builds 520.56.06, and it fails if I use linux 6.3 with the same error as your’s. If I use the default linux 5.15, it builds fine. But yea, you’re not running NixOS 23.05, and in NixOS 22.11, the solution is to not use linux 6.3. EDIT: And to be clear, it builds fine for linux 6.3 on nixos-23.05

thanks, ej. you spotted my mistake(s). i seem to have mismanaged channels and packages. for example i thought i had upgraded to 23.05 but had not. must have made a typo. need to get a better grip on what is on my system.

thank you to solene and ej for your help.
