Hello everybody,
I have a MSI GF65 laptop with a RTX 3060 (Max Q, I suppose). I dual boot Ubuntu and Windows and under Windows, everything works great. Under Ubuntu (even after fresh intall), however, the GPU is not detected at all.
The About screen names the graphics device as “Mesa Intel® UHD Graphics (CML GT2)”.
The output of lspci | grep VGA
is:
00:02.0 VGA compatible controller: Intel Corporation UHD Graphics (rev 05)
01:00.0 VGA compatible controller: NVIDIA Corporation Device 2520 (rev a1)
I have seen many other posts where the GPU is not detected correctly, but normally at least lspci lists the model name, right? Same for lshw -c video

Unsurprisingly, nvidia-smi
“failed because it couldn’t communicate with the NVIDIA driver.” Also, prime-select nvidia
only returns “Info: the nvidia profile is already set”.
I have already tried various suggested solutions from other posts, including removing a file that blacklists nvidiafb, and disabling PSR from grub. Nothing worked so far, but to me it seems like my problem is even more profound than most others I saw here - I’ve never read anything about lspci not being able to name the GPU.
Finally, here’s my nvidia-bug-report.sh output:

I would be extremely grateful for any suggestions and hints on how to fix this.
Cheers
