DRM device recognition error on dual GPU devices
Thank you all for your efforts! My laptop consists of AMD integrated graphics and NVIDIA discrete graphics, and I need NVIDIA's dGPU to hard decode for my firefox, so I'm trying to use vainfo to check that the vaapi is working, and I think I'm running into a problem.
Here are the details:

I'm not quite sure the reason for this, it seems amd's iGpu is recognised as a DRM device. It's a bit mind boggling.

Obviously, it worked. Now the big question becomes how to set the DRM device to /dev/dri/renderD128.
This seems like a strange issue, it seems that /dev/dri/renderD128 can be set as the default DRM device via an environment variable. But I failed, I tried WLR_DRM_DEVICES (which caused Hyprland to crash), MOZ_DRM_DEVICE (which didn't seem to have any effect,Firefox still doesn't try to hard-decode, even though I've set it up.).
I am noticing a similar issue, but I only have one GPU in my system.

Unfortunately multiple GPUs can pose a problem. Firefox seems to only want to run on the default device, and if that device isn't the NVIDIA one, then even if you set the correct NVD_GPU settings, Firefox won't be able to import the frames that the driver exports.
I actually got it to work.
It was very hard, but I did it:

I use floorp, firefox fork
It's working for me, too.

Here's the thing, vainfo still shows the wrong drm device, but firefox can hardware accelerate after adding the MOZ_DRM_DEVICE and __NV_PRIME_RENDER_OFFLOAD environment variables. This is my method, you can try it.

I have an intel iGPU laptop with an Nvidia eGPU and I use Debian trixie OS with X11. This driver works perfectly fine if I start X directly on eGPU, but I usually prefer to have my X on iGPU and offload stuff to eGPU, so that I can easily unplug it if I need to move. I tried all the env vars mentioned here, including MOZ_DRM_DEVICE, but unfortunately I haven't been able to get it working: I get isNvidiaDrmFd Invalid driver for DRM device: i915 no matter what :(
Here is my exact command line:

In Firefox's config I have media.ffmpeg.vaapi.enabled, media.rdd-ffmpeg.enabled, gfx.x11-egl.force-enabled and widget.dmabuf.force-enabled all set to true. My firefox version is 128.6.0esr
If someone has any more ideas how to make it work, I'd be grateful! :)
@morgwai My setup looks basically the same, except my Nvidia in onboard (Quadro T2000 Mobile), and I have exactly the same issue. I'm using NixOS
My full config is here ( not that this will be meaningful for Debian ) https://github.com/randomizedcoder/nixos/tree/main/laptops/t
@morgwai
Blacklisting i915 definitely make my Nvidia experience better, although this option might not work for you.
Tracking in this thread https://discourse.nixos.org/t/nvidia-open-breaks-hardware-acceleration/58770/
@randomizedcoder, blacklisting i915 defeats the whole purpose ;-] Second, having i915 loaded does not break Nvidia hardware video decoding for me (it works fine if only X is started on the Nvidia regardless of i915 being loaded). My problem is with Firefox choosing a wrong device despite of having all the env vars defined similarly to @acdcbyl .
Having written the above actually made me realize I should ask this: @acdcbyl, which version of Firefox are you using?
Also, there's one more interesting detail regarding my setup that I've recently noticed: I don't have drm display available in vainfo:
morgwai@morgwai-xps13:~$ vainfo --display help
Available displays:
wayland
x11
morgwai@morgwai-xps13:~$ vainfo --display drm --device /dev/dri/renderD129
error: failed to initialize display 'drm'
This made me think: maybe I lack some "drm abstraction layer" that actually allows Firefox to choose a drm device?
