Hi
I have just received my new Dell Alienware m18 with an RTX4090 and I run it under Ubuntu 22.04 LTS. When I type “lspci | grep -i NVIDIA” in the terminal it doesn’t see my GPU despite the fact that I typed “sudo update-pciids” before. I join the bug report that I generated. Could you please help ?

Hi thierry-arlandis,

I am not sure what to say, but if I check the log I find this:

/usr/bin/lspci -nn

00:00.0 Host bridge [0600]: Intel Corporation Device [8086:a702] (rev 01)
[..]
01:00.0 VGA compatible controller [0300]: NVIDIA Corporation GN21-X11 [10de:2757] (rev a1)

and the nvidia-smi --query also looks completely normal

/usr/bin/nvidia-smi --query

Maybe a typo when you tried lspci?

Hi Markus

Thanks for your quick reply, no typo I tried again but the strange thing is that I have just installed CUDA 12.3, CUDNN 8.9.5.30 and run Yolov4 on this PC and it is working correctly at about 49Hz average, which means that the it finds the RTX4090. It’s a mystery.

The return from lspci | grep -i NVIDIA is
01:00.0 VGA compatible controller: NVIDIA Corporation GN21-X11 (rev a1)
01:00.1 Audio device: NVIDIA Corporation Device 22bb (rev a1)

I don’t know what to say.

Well, no worries, glad to hear things are working now.

Who knows what happened there.
