Nvidi driver installed but graphic card not detected

[abtb]

Hello,

My computer is under Ubuntu 22.04 (well Linux Mint, 21.1, but it’s the same) and has an Nvidia T600 GPU.
My kernel is 6.1.0-x64v3+.
My secure boot is disabled.
My installed driver is nvidia-driver-535 and should support Nvidia T600.

Nvidia X server settings doesn’t show any graphic card.
Running prime-select query displays

Running lspci -vnnn | perl -lne 'print if /^\d+\:.+(\[\S+\:\S+\])/' | grep VGA displays

00:02.0 VGA compatible controller [0300]: Intel Corporation Alder Lake-P Integrated Graphics Controller [8086:4626] (rev 0c) (prog-if 00 [VGA controller])

Below my nvidia bug report.

Thanks a lot for your help !

Don’t know if it’s related but I don’t have the Discrete graphic option in BIOS, so I’m staying on the Hybrid option

@generix sorry to identify you, but I saw you started answering the problem on the mentioned link (Video-nvidia driver is not detecting my graphic card), may you please help me ?
Thanks a lot !
Here is the result of

~$ grep nvidia /etc/modprobe.d/* /lib/modprobe.d/*

There are no nvidia kernel modules installed, how did you install the driver?

[abtb]

Thanks for the answer !

I installed it with Linux Mint Driver Manager

Also tried NVIDIA official script (NVIDIA-Linux-x86_64-465.27.run)

[abtb]

Tried ton install latest version through driver manager, without more result.

[generix]

Please post the output of
dkms status

[abtb]

Here is the ouput :
nvidia/545.23.06: added

[generix]

Please reinstall the kernel headers by running
sudo apt install --reinstall linux-headers-$(uname -r)
Afterwards, post any errors and the output of
dkms status
again.

[abtb]

When I run the command, I get the following error :

Reading package lists... Done
Building dependency tree... Done
Reading state information... Done
E: Unable to locate package linux-headers-6.1.0
E: Couldn't find any package by glob 'linux-headers-6.1.0'

For information, I used that kernel : GitHub - johan12345/linux: Linux kernel source tree, with patches for https://gitlab.freedesktop.org/drm/intel/-/issues/5531 applied because it had a required patch for my computer, I don’t know if this can be related.

[abtb]

Tried Install linux-headers on debian unable to locate package - Stack Overflow first answer, but same error

[generix]

This results from the custom built kernel. You’ll have to create a symlink in /lib/modules/$(uname -r)/build to the kernel source directory where you built that kernel.

[abtb]

Oooops, I deleted the kernel’s built folder to make place :/
I rebuilt the kernel in the same folder, so the broken symlink is now fixed, now I can do $ cd /lib/modules/$(uname -r)/build and it works, showing the files and folders of the kernel (arch, block, built-in.a, etc.)
I rebooted my computer and relaunched the sudo apt install --reinstall linux-headers-$(uname -r) command, but same result.
Thanks again for your help.

[generix]

Please run
sudo dkms install nvidia/545.23.06
post any errors displayed and the output of
dkms status
afterwards.

[abtb]

First command result’s : Module nvidia/545.23.06 already installed on kernel 6.1.0+ (x86_64).
dkms status result’s : nvidia/545.23.06, 6.1.0+, x86_64: installed

[generix]

The nvidia driver is installed and should be working (after a reboot). If not, please run nvidia-bug-report.sh as root and attach the resulting nvidia-bug-report.log.gz file to your post.

[abtb]

Right ! Did the problem got solved by fixing the symlinks ?- (to put it as solution answer)

[generix]

Yes. The reboot afterwards then triggered dkms to build/install the nvidia driver.

[abtb]

Okay
Thanks again for taking time to help :D
