[SOLVED] NVIDIA dGPU disabled at kernel launch, how to re-enable it?

ItsFireStorm · 2025-03-25 11:10:27

First things first, a month ago, I was using Hyprland as my everyday DE due to it's customizability and blah blah blah...

The issue is that Hyprland isn't fully compatible with NVIDIA, and as a means to not completely slow down my laptop whenever I ran on battery whilst using Hybrid graphics, I disabled my NVIDIA dGPU at kernel launch (do not ask me how I did it, I have no idea as I completely forgot :D). After some months of using Hyprland, I switched to GNOME, and instantly fell in love with it since it fixed some issues I had with Hyprland, and also offered a similar level of customization I managed to do in my Hyprland workflow.

Here's the problem, ever since I switched, I wanted to enable the NVIDIA GPU back, however, I never wrote down how to enable it, and looking at my browser history I cannot remember the forum I checked on how to disable it, and I wanted to ask here if any of you guys could help me track down how to enable it.

Here's a few things that I've tried:

Installed the nvidia-open drivers and nouveau, it allowed me to enable nouveau with modprobe, but nvidia was unsuccessful and gave this output:
```
modprobe: ERROR: could not insert 'nvidia': No such device
```
as expected.
Removing modprobe.d configurations that blacklisted nvidia drivers.

I will try to search for more solutions, I'll keep this post updated as I go.

maybe you don't have the driver for your -zen kernel? you need nvidia-open-dkms (and zen kernel headers)

edit:
or you need to remove "kms" from mkinitcpio HOOKS

Whenever you are facing an issue, it is very important to do research first and i'll state why that should have been the first move for your issue.

The wiki page for Nvidia states that for your kernel, the zen kernel, you would need nvidia-open-dkms, or nvidia-dkms (with the open being recommended by upstream).

This should be a good thing to remember. Whenever i break my machine, i always go through the install guide first to see if i did anything similar to possibly affect anything established in the guide, from there I just go through the articles in the wiki relevant to my issue at hand.

Did you disable it in the system firmware settings? I don't know why people are talking about missing modules when they're obviously there.

What do you get from `lspci -k -d ::03xx`?

I did not switch off the dedicated graphics in the system BIOS, as I can use the dedicated graphics in Windows without issue.

3rd link below. Mandatory.
Disable it (it's NOT the BIOS setting!) and reboot windows and linux twice for voodo reasons.

Did you maybe enable resizable BARs in your UEFI/BIOS?

I'd have to note that I do not have Windows installed in my laptop's drive, I rather use an external SSD to boot to it. I'm pretty sure Fast Boot is also turned off there.

I also do not recall my BIOS having an option to enable 'BARs' much less I know what it means.

seth · 2025-03-26 21:16:03

The install location doesn't matter at all - don't be "pretty sure", check.

https://en.wikipedia.org/wiki/PCI_confi … numeration - check your BIOS config about this, too.
Also test a non-zen kernel, preferably the LTS one.

ItsFireStorm · 2025-03-27 09:58:48

I made sure to disable Fast Boot in Windows following your link, that's checked.

I also didn't find any option for Resizable BARs, I don't think my BIOS supports it.
Tried Linux LTS with the nvidia-open-lts package, it still doesn't work, I'll attach the lts kernel boot log if that's helpful.

Mar 27 10:54:04 ARCHUS kernel: nvidia-modeset: Loading NVIDIA UNIX Open Kernel Mode Setting Driver for x86_64 570.133.07 Release Build (archlinux-builder@)

How about the not-open driver?
Why do you issue "intel_iommu=on"? Remove that.

ItsFireStorm · 2025-03-28 07:25:29

Finally solved it!

Turns out when I had Hyprland as my DE I created a config file in /etc/udev/rules.d that blocked the NVIDIA card by Product and Vendor ID, I removed that file and it now shows up.
