NVIDIA Module Verification Failed (ASUS N56VJ double graphic card: GT 635M + Intel i915)

Hello!

I have an ASUS N56 which has a double graphic card, from NVIDIA and Intel.

I would like to use this laptop with an external HDMI screen only. Before installing any driver, something was displayed in the monitor but not useful at all (like wrong resolution rendering or something)

So I proceed by installing the NVIDIA drivers from this page: SDB:NVIDIA drivers - openSUSE Wiki

I followed the YaST approach and everything seems all right, but after reboot the external monitor is now always black.

Through different posts I think that my problems are:

  1. The module license is not trusted by the kernel, and therefore is not loaded:

  1. The Intel card is always loaded, (preventing the NVIDIA card to be loaded?) i915 is active

:thinking:

So, I don’t know if I should proceed with the installation of NVIDIA_SUSE_Prime or if first I should manage to register the NVIDIA module so the registration does not fail, similar to what is described here from Secureboot (which I tried but I dont understand the reference, so I implemented this command:

mokutil --import /usr/share/nvidia-pubkeys/MOK-nvidia-gfxG0-<driver_version>-<kernel_flavor>.der --root-pw

as

mokutil --import /usr/share/nvidia-pubkeys/MOK-nvidia-gfxG05-470.256.02-lp156.61.1-Linux 6.4.0-150600.21-default.der --root-pw

which failed of course :sweat_smile:

As my goal is to use the HDMI monitor, I don’t care about the Intel i915, so If I could manage to use only the NVIDIA would be great.

Thanks a lot for any help!

Cheers,

How did you chose the driver version? According the Nvidia driver search page, this one needs v390 aka G04 as it is a Fermi card.

Hello,
I choosed it based on a table, that I thought I saw here: Determination_of_driver_version
but I think was lack of attention because there is no reference between cards and drivers there.
Ill try again with the right driver and if problems ill create another post.
Thanks a lot for taking the time and for pointing it out!

I will follow up with the G40 drivers, but cant find them in the repo, I will follow this post https://forums.opensuse.org/t/geforce-gt-730-is-not-recognized-after-installing-proprietary-drivers/177194 , seems from the NVIDIA page the driver is available, although there is a warning in the OpenSUSE instruction page that the driver wont work with the kernel 6.6.x, Leap 15.6 has kernel 6.4, so I will give it a try
