Nvidia-driver-assistant misdetects older GPUs due to faulty NVIDIA metadata

megvadulthangya · 30 December 2025 17:53

Issue Description

Custom Manjaro Awesome ISOs built after December 12, 2025 fail to boot when proprietary NVIDIA drivers are selected on systems with GTX 750 Ti graphics cards. The boot process consistently hangs at “Starting Show Plymouth Boot Screen.”

Diagnostic Steps Taken

1. ISO Comparison

Compared working ISO (2025-12-12) with non-working ISOs (2025-12-28, 2025-12-30)
Used pacman -Qs and pacman -Ss to analyze installed packages

2. Package Analysis Findings

Working ISO: Contains linux612-nvidia (580.105.08-5)
Non-working ISOs: Missing linux612-nvidia, contains only linux612-nvidia-open (580.119.02-3)

3. Build Configuration Investigation

Examined iso-profiles/shared/Packages-Mhwd file
Found line: >nonfree_x86_64 KERNEL-nvidia
This line appears to resolve differently in recent builds

4. Modification Attempt

Added explicit line to Packages-Mhwd:

>nonfree_x86_64 linux612-nvidia

Rebuilt ISO with this modification.

5. Result of Modification

Even with the explicit linux612-nvidia line in Packages-Mhwd, the resulting ISO still contains only linux612-nvidia-open (580.119.02-3) and not the standard linux612-nvidia package.

Current Status

The standard proprietary NVIDIA driver package (linux612-nvidia) is not being included in ISOs
The NVIDIA open kernel module (linux612-nvidia-open) is installed instead
Manual installation of linux612-nvidia in a live session allows successful boot

Questions for the Manjaro Community

What is the recommended approach to ensure the standard proprietary NVIDIA driver (linux612-nvidia) is included in custom ISO builds instead of the open kernel module (linux612-nvidia-open)?
Has there been a change in package resolution where KERNEL-nvidia now defaults to the open module variant? If so, how can custom ISO builders override this for older NVIDIA GPUs?
Are there specific configuration options or build parameters that control which NVIDIA driver variant gets included in the ISO?
For users with older NVIDIA GPUs (like GTX 750 Ti), what is the officially supported method to maintain compatibility in custom Manjaro builds?

Technical Context

GPU: NVIDIA GTX 750 Ti (Maxwell architecture)
Kernel: linux612
Build method: GitHub Actions with manjaro-iso-action
ISO profile: awesome

We’ve documented our diagnostic process and attempted solutions, but the issue persists. Any guidance on proper configuration for older NVIDIA GPU support would be greatly appreciated.

Most nVidia 700 series GPUs are based on Kepler Architecture and do not work with current nVidia drivers

For standard Manjaro ISOs user can boot system with NON-FREE open-source driver to install Manjaro, and then install 470.xx legacy driver in Manjaro Settings Manager GUI or:

mhwd -i pci video-nvidia-470xx

For a Maxwell GPU, check if there are any 570xx or 575xx legacy drivers available

mhwd -l

IT’s possible the file has been removed from Packages-Desktop or Packages-Mhwd.

[SOLVED] NVIDIA “No such device” error and Open-source driver conflict on Custom ISO builds (GTX 750 Ti)

Thanks for the suggestions! I managed to solve this by forcing the build system to prioritize the proprietary driver and completely purging the open-source kernel modules from the build profile.

The Issue:

For Maxwell cards like the GTX 750 Ti, the new nvidia-open kernel modules (580.xx) are often detected but fail to initialize, resulting in:

modprobe: ERROR: could not insert ‘nvidia’: No such device.

Even if you try to add the proprietary driver to your profile, the Manjaro build system might favor the “Open” version due to its default priority in the mhwd database, leading to a package conflict or a broken Live environment.

The Solution:

Force Proprietary Drivers in Packages-Root:

Add the closed-source drivers directly to your Packages-Root (or Packages-Desktop) file. This ensures they are installed during the base image creation, bypassing the ambiguity of hardware detection:
```
linux612-nvidia
nvidia-utils
nvidia-settings
lib32-nvidia-utils
egl-gbm
egl-wayland
egl-x11
```
Purge the “Open” driver from Packages-Mhwd (Crucial Step):

You must completely remove/comment out any reference to the open-source NVIDIA modules in your Packages-Mhwd file. If the builder sees KERNEL-nvidia-open in the list, it may attempt to install it as the “default” or “newer” option, which conflicts with and replaces the working proprietary driver.
- Action: Delete or comment out lines containing >nonfree_x86_64 KERNEL-nvidia-open. —> And all other open what we find…
Result:

By stripping out the “Open” alternative and hard-coding the proprietary packages into the Root layer, the ISO boots with the correct driver (nvidia v: 580.xx) and full 3D acceleration.

Diagnostic check on the working Live ISO:

inxi -G now correctly shows:

Device-1: NVIDIA GM107 [GeForce GTX 750 Ti] driver: nvidia v: 580.119.02

Display: x11 server: Xorg … driver: X: loaded: nvidia

Hopefully, this helps anyone building custom Manjaro spins for older (but still supported) Maxwell hardware!

Note for Manjaro GODS / MHWD Maintainers: While the above fix works for custom ISO builds, it is more of a “forced override” than an elegant solution. It seems the current mhwd-db prioritization for Maxwell-based cards (like the 750 Ti) defaults to the nvidia-open modules, which are unfortunately incompatible or unstable for this specific architecture, despite being the “latest” version.

If there is a more elegant way to adjust the mhwd priority within the ISO profile (without hard-coding packages into Packages-Root), I’m all ears! For now, purging the “open” references from the profile was the only way to ensure a working Live environment for this GPU.

philm · 31 December 2025 06:26

As NVIDIA already stated, nvidia-open is not supporting older cards at all.

mhwd adopted nvidia-driver-assistant which is used to define if the hardware is supported by open or proprietary drivers. Maybe that tool suggests the wrong driver on your device. These are only for Turing and newer architectures …

Sources can be found here: Packages / extra / nvidia-driver-assistant · GitLab

Example to check if the open driver is used from mhwd-config: [[ "$(nvidia-recommended-driver)" == "open" ]] && DEPKMOD="nvidia-570xx-open"

megvadulthangya · 31 December 2025 09:31

Hi @philm, thank you for taking the time to respond!

I’ve slept on it and I agree. My ‘hacky’ solution of forcing packages into Packages-Root is not the right way to go. I also want to clarify that I checked my logs and I already had this glitch on an ISO I built on the 28th, so it wasn’t caused by the mhwd-db update from the 29th — it was indeed the driver-assistant logic.

I’ve decided to revert my changes to keep the ISO clean. However, seeing the source code you linked for nvidia-driver-assistant, I’m planning to fork it and refine the detection logic for Maxwell and Pascal architectures. These cards are currently being misidentified as “open-compatible” when they actually require the proprietary flavor.

I will test my changes on my custom builds and I’ll get back to you with the results. Since this topic might close in 3 days, I will either open a new one or reach out via GitLab (but im not sure about this, couse i dont have acc) once I have a working patch that correctly filters these GPU families.

Thank you for the great work you and the team are doing with Manjaro, and thanks for pointing me to the source. It helped me understand the underlying process much better!

philm · 31 December 2025 16:23

@linux-aarhus is also working on the assistant. We might have some to be tested soon I hope. Might be good when you crosscheck when ready.

linux-aarhus · 31 December 2025 17:01

@megvadulthangya

Could you supply the Module Alies value of from some the older Nvidia cards if possible (for nvidia-driver-assistant testing purpose)

hwinfo --gfxcard

Also the corresponding output from

nvidia-driver-assistant

megvadulthangya · 1 January 2026 02:34

Hi there!

I have a test version of the nvidia-driver-assistant package in my custom repository: https://repo.gshoots.hu. The source code is available here: https://github.com/megvadulthangya/nvidia-driver-assistant/tree/v3.

I’d like to include this package in a custom Manjaro Awesome ISO for live testing. Currently, the build system always pulls the version from the official Manjaro repository instead of mine.

Could you advise on the proper way to include a package from a custom repository in an ISO build? My goal is to have it installed from my repo rather than the official one.

Important note: The actual PKGBUILD I’m using to build this package isn’t in the main repo - it’s located here: https://github.com/megvadulthangya/manjaro-awesome/tree/main/nvidia-driver-assistant.

Regarding the previously mentioned hardware information: my version handles detection differently, so it might not be necessary. But if you think it would still be helpful for testing, I’m happy to provide the requested data today.

Thanks for your help!

linux-aarhus · 1 January 2026 05:08

Thank you for sharing your source.

I have been thinking something similar - but it is still thoughts - so I would like to borrow from you - if I may - properly credited and all.

philm · 1 January 2026 05:55

Custom repo needs to been added in pacman.conf. the repo order needs to been given that custom is on top when a package has the same name as within official repos.

@linux-aarhus – Thank you for the detailed feedback and for sharing the GPU list. It’s very useful and confirms the focus of my detection logic. I’m glad to hear the patched assistant works well, and I’m open to you using any ideas from my approach with proper credit.

@philm – Thanks for the tip about the pacman.conf order. I’ve already tried this by modifying iso-profiles/community/awesome/pacman-default.conf (and also the standard pacman.conf).

I placed my custom repo at the top:

[manjaro-awesome]
SigLevel = Optional TrustAll
Server = https://repo.gshoots.hu/

However, the ISO build still pulls the official nvidia-driver-assistant, not mine.

Is there a specific build stage or another configuration file I should adjust to ensure my repo is prioritized? (I build on github, based on your YT video) … if its matters anything..

linux-aarhus · 1 January 2026 09:24

@linux-aarhus – Sorry for the delay, I couldn’t get to the machine until now.

Note: The nvidia-driver-assistant correctly reports “Not supported” for the open kernel module on this card, which makes sense since the GTX 750 Ti (Maxwell) is not supported by nvidia-open. However, the ISO build issue likely stems from some conflict or default that still tries to use the open version.

I also have a GTS 450 (Fermi) card, but unfortunately I can’t test it right now because my soldering equipment is spread out where the monitor would be.

I hope this information helps improve the detection logic. If you need any other details or tests with this hardware, please let me know.

Thank you for your work on this!

Precisely this card pci:v000010DEd00001380sv00001458sd000036CAbc03sc00i00 we have in a short-list of simulated gpu.

That is why I asked for the Device ID (Vendor) 1380

It turns out that where the 740A returns a legacybranch property

    {
      "devid": "0x1292",
      "name": "GeForce GT 740M",
      "legacybranch": "470.xx",
      "features": [
        "hdmi4k",
        "vdpaufeaturesetD"
      ]
    },

The 750 has no legacybranch property in the json data file supplied by Nvidia.

    {
      "devid": "0x1380",
      "name": "NVIDIA GeForce GTX 750 Ti",
      "features": [
        "hdmi4k",
        "vdpaufeaturesetE"
      ]
    },

Thus can hope for Nvidia to update their data file at some point - that would be number one - I am currently trying wrap my head around some way of reliably determine where a device without legacybranch property should be categorized - I have to dig deeper into the nvidia device detection function to figure that out.

Oh - I think I am on to something.. hang on…

This is a hair-pulling experience

Continuing the story with the 750Ti - it turns out that Nvidia has changed the properties for the device

From

      "features": [
        "hdmi4k",
        "vdpaufeaturesetE"
      ]

To

    {
        "devid": "0x1380",
        "name": "NVIDIA GeForce GTX 750 Ti",
        "legacybranch": "580.xx",
        "features": [
            "kernelopen"
        ]
    }

Which still doesn’t explain why the script returns unsupported - but know that I know where the kernelopen property comes from … the investigation is ongoing…

Normally mhwd -l -d should print out which drivers mhwd would install. Within the MHWDCONFIG file we have a check, which uses nvidia-driver-assistant to check if the open module is supported:

#!/bin/bash

CONKMOD="nvidia-390xx nvidia-470xx nvidia-575xx nvidia"
[[ "$(nvidia-recommended-driver)" == "open" ]] && CONKMOD+=" nvidia-570xx"
echo "CONKMOD: $CONKMOD"
DEPKMOD="nvidia-570xx"
[[ "$(nvidia-recommended-driver)" == "open" ]] && DEPKMOD="nvidia-570xx-open"
echo "DEPKMOD: $DEPKMOD"

So I wonder which DEPKMOD value is selected on your hardware. Normally it should stay with nvidia-570xx since the output is not open.

This is a test with the newer version from testing and unstable by simulating an older card:

#!/bin/bash

CONKMOD="nvidia-390xx nvidia-470xx nvidia-575xx nvidia"
[[ "$(nvidia-driver-assistant --mhwd --simulate-gpu 740A)" == "open" ]] && CONKMOD+=" nvidia-570xx"
echo "CONKMOD: $CONKMOD"
DEPKMOD="nvidia-570xx"
[[ "$(nvidia-driver-assistant --mhwd --simulate-gpu 740A)" == "open" ]] && DEPKMOD="nvidia-570xx-open"
echo "DEPKMOD: $DEPKMOD"

Output is then:

sh ./test.sh                                                     ✔ 
CONKMOD: nvidia-390xx nvidia-470xx nvidia-575xx nvidia
DEPKMOD: nvidia-570xx

Hmm, normally both packages should been included based on the line: shared/Packages-Mhwd · master · Profiles & Settings / iso-profiles · GitLab and gets also added to the mhwd overlay: https://gitlab.manjaro.org/-/snippets/1177/raw/master/mhwd-build.log
