 Posted: Thu Feb 08, 2024 1:11 pm Post subject: [SOLVED] Failed to initialize the NVIDIA kernel module |
 |
|
I reinstalled my computer from scratch and I have an issue with nvidia when trying to make optimus works.
Without any /etc/X11/xorg.conf, it works fine.
If I try to follow https://wiki.gentoo.org/wiki/NVIDIA/Optimus, X fails.
I generated my Xorg.conf with `nvidia-xconfig --prime`
I have run out of idea...
Here is my xorg.conf : https://pastebin.com/raw/psKA2z3V
Here is my Xorg.0.log : https://pastebin.com/raw/fkMFqpgx
Here is dmesg : https://pastebin.com/raw/rxzVaqNK
Here is the result of lspci :
| Code: |
$ lspci | grep -E "VGA|3D controller"
00:02.0 VGA compatible controller: Intel Corporation CoffeeLake-H GT2 [UHD Graphics 630]
01:00.0 3D controller: NVIDIA Corporation GP107M [GeForce GTX 1050 Ti Mobile] (rev a1)

So.. what's the problem?
NVIDIA's official documentation is typically all you need for prime (it also mentions that the X server will typically handle everything automatically and there's no need to go out of your way to break things). Will also point out some environment variables to control what's used too.
https://download.nvidia.com/XFree86/Linux-x86_64/535.154.05/README/primerenderoffload.html
Not that I have such a setup myself, so just going with what I typically hear and how people don't even need a Xorg.conf. |

Maybe I'm wrong but I thought my nvidia card wasn't used without this.
Here is what I have in nvidia-smi :

Is it normal I have no running processes ? Even when I run a video
On my other computer (with the xorg.conf from `nvidia-xconfig --prime`), I have X and gnome-shell in there. |

It seems the issue was only due to my user not being in the video group...
Sorry for bothering you and thank you for your help. |

| Hi, I have the same problem. Why do I still have problems after adding users to the video group? |
