[elrepo] Having trouble installing nvidia drivers on a fresh minimal install of CentOS 7

[Gesing, Mark (NRCan/RNCan)]

Solved:

My problem was that UEFI secure boot was enabled, and preventing me from loading the nvidia driver because it's signature wasn't trusted.

My solution was to follow these instructions to disable secure-boot: https://wiki.ubuntu.com/UEFI/SecureBoot/DKMS

Hi everyone,

I am working on a new machine which has 2x Nvidia Quattro P-2000 as GPUs.

I just got finished doing a fresh minimal install of CentOS 7, and am now trying to install the NVIDIA drivers from elrepo.

I followed the instructions to get elrepo added: http://elrepo.org/tiki/tiki-index.php

I then installed kmod-nvidia, nvidia-detect, nvidia-x11-drv-libs.i686.

After a restart nvidia-smi returns:
"NVIDIA-SMI has failed because it couldn't communicate with the NVIDIA driver. Make sure the latest NVIDIA driver is installed and running"

`lsmod | grep -i nvidia`
Returns nothing

`sudo modprobe nvidia`
"modprobe: ERROR: could not insert `nvidia`: Required key not available

`yum list installed | grep -i nvidia`
"""
Loaded plugins: fastestmirror, nvidia
kmod-nvidia.x86_64                     418.56-1.el7_6.elrepo           @elrepo
nvidia-detect.x86_64                   418.43-1.el7.elrepo             @elrepo
nvidia-x11-drv.x86_64                  418.56-1.el7_6.elrepo           @elrepo
nvidia-x11-drv-libs.x86_64             418.56-1.el7_6.elrepo           @elrepo
yum-plugin-nvidia.noarch               1.0.2-1.el7.elrepo              @elrepo
"""

It looks to me like I have all the right packages installed, yet, the NVIDIA driver is not available. . .

What am I doing wrong?

Thanks,

Mark.
