Posted: Sat Feb 17, 2024 10:23 am Post subject: [SOLVED] FATAL: Module nvidia not found in director

I am currently deploying my Gentoo (systemd). Everything goes well, but nvidia-driver.
Here are operations that I did so far:
1. To avoid issues caused by inappropriate kernel configuration, the gentoo-kernel-bin was currently installed. Here is the output of command `uname -a`:

Code:

Linux ubuntu.lan 6.7.4-gentoo-dist #1 SMP PREEMPT_DYNAMIC Tue Feb 6 12:44:25 -00 2024 x86_64 Intel(R) Core(TM) i9-9900 CPU @ 3.10GHz GenuineIntel GNU/Linux

2. USE="dist-kernel" has been set in make.conf to make sure that nvidia driver auto rebuild will be triggered in every kernel update.

3. Manually map "/usr/src/linux" symbolink to make sure that it points to the correct kernel that I want to build against. Here is the output of `ls -l /usr/src`

Code:

guanzd@ubuntu /usr/src $ ls -l
total 4
drwxr-xr-x 1 root root 36 Feb 16 23:11 config
lrwxrwxrwx 1 root root 23 Feb 17 12:44 linux -> linux-6.7.4-gentoo-dist
drwxr-xr-x 1 root root 2038 Feb 17 00:27 linux-6.2.12-gentoo
drwxr-xr-x 1 root root 2054 Feb 17 11:50 linux-6.7.4-gentoo
drwxr-xr-x 1 root root 346 Feb 17 16:22 linux-6.7.4-gentoo-dist

As you may see that, I have more than 1 kernel have been installed historically. It is because I start my installation in virtual box in April, 2023. Last week, I decided to migrate Gentoo to host machine. On kernel "linux-6.2.12-gentoo", I tried to installed latest version of nvidia-drivers. Fortunately, it worked! I found "video" folder in '/lib/modules/linux-6.2.12-gentoo" ! Then, and tried to configure "linux-6.7.4-gentoo" kernel and compile it for the latest nvidia-drivers, but failed with "Module nvidia not found in directory". Finally, I installed the distribution kernel "linux-6.7.4-gentoo-dist" and removed the above 2 kernels, but failed with "FATAL: Module nvidia not found in directory".
Here is list for kernel installed on my system:

Code:

guanzd@ubuntu /usr/src $ eselect kernel list
Available kernel symlink targets:
[1] linux-6.7.4-gentoo-dist *

4. Running compilation on target kernel. Currently, I am running compilation on linux-6.7.4-gentoo-dist for nvidia driver kernel module.

5. I have tried to run "emerge -e nvidia-drivers", failed with "module nvidia not found"

6. Put USE flag "modules" into make.conf, and re-compiled nvidia-drivers. Nothing changed.

Here is my make.conf file:

Code:

# /usr/share/portage/config/make.conf.example

# GCC
CFLAGS="-march=haswell -O2 -pipe"
CXXFLAGS="${CFLAGS}"
CHOST="x86_64-pc-linux-gnu"

What else should I do to get nvidia-drivers working?
Thanks!

Your make.conf has:

Code:

=" ... -modules ..."

USE=-modules on nvidia-drivers will unsurprisingly not give you modules (disabling that is intended for chroot or prefix where the modules were installed some other way).

Thanks for your reply! I forgot to mention that I put "USE=modules" intentionally to see if there are any changes will be made. Because, in wiki(https://wiki.gentoo.org/wiki/NVIDIA/nvidia-drivers), it says that USE flags "modules" represents "Build the kernel modules".

As expected, it failed with "Module nvidia not found in directory".

You're currently doing "modules -modules" (aka enable it then disable it)

I'd suggest looking at the portage output to see whether it is really enabled with -v/--verbose, e.g.

Code:

$ emerge -pvq nvidia-drivers
[ebuild R ] x11-drivers/nvidia-drivers-550.40.07 USE="X dist-kernel modules static-libs strip tools -kernel-open -modules-compress -modules-sign -persistenced -powerd -wayland" ABI_X86="32 (64)"

shows modules rather than -modules.

Also it's enabled by default, so there's no need to add "modules" to your make.conf. The problem is that you are explicitly disabling it.

Ah... got it! I just copied make.conf from online source without careful review.

I figured it out! Thank you soooo much!
