Trying to make everything work on a legion 7i 2022 with intel CPU and NVIDIA GPU with a dual boot setup

juristpail · January 19, 2023, 6:03pm

It is confusing, because nvidia-smi doesn’t work at all. It says command not found.

Edit1: Yes, Its not freezing, but I don’t think nvidia is installed, because nvidia-smi doesn’t work.

ricklinux · January 19, 2023, 6:07pm

I don’t know anything about nvidia-smi. I only know what it shows. The driver is loaded? Before it wasn’t.
I was expecting it to remove all nvidia and run on the open source nouveau. So something still may not be correct.

Check what nvidia packages are installed. Maybe?

pacman -Qi nvidia

juristpail · January 19, 2023, 6:10pm

pacman -Qi nvidia
error: package 'nvidia' was not found

This is again confusing

Can i just ask a couple things? Do you still have lts kernel installed? Did you install the lts headers also?

juristpail · January 19, 2023, 6:14pm

yes, sure. I am not using lts kernel because it doesn’t support my wifi driver. This is my linux kernel

Linux gluon-alderlake 6.1.6-arch1-3 #1 SMP PREEMPT_DYNAMIC Mon, 16 Jan 2023 12:51:23 +0000 x86_64 GNU/Linux

Linux headers are also installed.

 uname -r
6.1.6-arch1-3

ricklinux · January 19, 2023, 6:15pm

So you don’t have the lts installed? You removed them?

juristpail · January 19, 2023, 6:16pm

yes. I don’t have the lts installed.

ricklinux · January 19, 2023, 6:16pm

Okay can we confirm this.

cat /etc/kernel/cmdline

juristpail · January 19, 2023, 6:17pm

cat /etc/kernel/cmdline
nvidia-drm.modeset=1 nvme_load=YES rw root=UUID=325f9be3-ba59-4b33-830f-8570e8c26ea5 ibt=off

This is it

ricklinux · January 19, 2023, 6:19pm

Okay… lets run a test.

nvidia-inst -t

Post the output after running this.

juristpail · January 19, 2023, 6:20pm

Here it is

ricklinux · January 19, 2023, 6:22pm

So it is showing removing Nouveau.

I think you should try running it without prime and see what happens first. Then reboot.

nvidia-inst

juristpail · January 19, 2023, 6:27pm

Ok, this seems to work,

Edit1: Thanks @ricklinux for having the patience to lead me through.

Okay so maybe it straightened out the installation of nvidia. But not sure where to go with prime from here? Does this laptop have switchable graphics? Have you checked the settings in the UEFI bios screen? It should have maybe switchable, discrete and maybe hybrid?

juristpail · January 19, 2023, 6:30pm

I do have a switchable graphics. On the UEFI bios I have enabled switchable graphics option.

ricklinux · January 19, 2023, 6:32pm

So i guess see now if this is working properly. I’m not the expert on all these different laptop hardware. I just know how should be some of it on the install side and some hardware side but not everything.

juristpail · January 19, 2023, 6:33pm

Thanks @ricklinux, I am happy I can experiment with some ML or CUDA codes. Thanks a ton!

ricklinux · January 19, 2023, 6:34pm

Thanks for sticking with it and not giving up too easily.

juristpail · January 19, 2023, 8:10pm

Let me summarize the solution in total:

ibt=off is SUPER important to enable using NVIDIA GPUs, credits to @mrvictory .
I have systemd-boot, so I needed to put ibt=off in /etc/kernel/cmdline and sudo reinstall-kernels. Then reboot.
With help from @ricklinux I first installed nouveau to remove anything nvidia related using
nvidia-inst -n
Then reboot.
The ultimate step nvidia-inst to cleanly install nvidia drivers and then reboot.
Thanks! @mrvictory @ricklinux
