How I fix this issue NVIDIA-SMI has failed because it couldn't communicate with the NVIDIA driver. Make sure that the latest NVIDIA driver is installed and running

install_nvidia_driver.md

I am no longer abe to monitor this post , I have decided to move everything to my personal blog for better monitoring.

sudo apt-get purge nvidia-*
sudo apt-get update
sudo apt-get autoremove
and

apt search nvidia ( check latest version)

sudo apt install libnvidia-common-<version>
sudo apt install libnvidia-gl-<version>
sudo apt install nvidia-driver-<version>

Worked for me (Ubuntu 22.04 on a dell inspiron 5510) after I did the reboot on secure mode on, but with a slight detail: The BIOS Audit Mode for the secure boot must be checked instead of the other (default) mode. If this default mode is checked, the drivers still does not load. After booting up with this config on, the driver is loaded and I could switch back the secure boot off again (maybe I could even leave it with secure boot on).

In my case I updated from 20 to 21 ubuntu, installed new nvidia drivers and it didn't work. The solution was to disable secure boot. Thanks lyh458

This is it!!

Disabling secure boot from the BIOS settings worked for me

it worked. Thank you !

Here is what worked for me ( I use Ubuntu 22.04)

1. Create a config file to blacklist the Nouveau driver:
   sudo tee /etc/modprobe.d/disable-nouveau.conf <<EOF blacklist nouveau options nouveau modeset=0 EOF
2. Regenerate the initial RAM filesystem:
   sudo update-initramfs -u
sudo apt purge 'nvidia-*' sudo apt update sudo ubuntu-drivers devices sudo ubuntu-drivers autoinstall sudo reboot

thanks! worked for Ubuntu 25.04 and nvidia-driver-570

Disabling secure boot and nvidia-driver-570 work for me. Thanks!

Thanks! Disabling Secure Boot fixed the issue with nvidia-driver-570 on Ubuntu 24.04.

Was all about disabling secure boot since unsigned modules can't be loaded with secure boot.

it works for me, thank you!

go to device manager -> click on display adapters -> click on nvidia gpu -> enable
This worked for me

@srisaisubramanyam Can you be a little bit more specific ?

how i install nvidia driver for 570 with cuda 12.90 supported

@farid1965 Depends on the OS. If Windows, you can find everything you need on the Download page for Drivers on the official site of Nvidia. If Linux, try getting the one from your distro's package manager. Should be something like (correct me if I'm wrong) nvidia-driver-{driver_version} (at least on Debian).

Check If the NVIDIA Kernel Module Is Loaded
Open a terminal and run:

bash

lsmod | grep nvidia
If this returns nothing, the kernel module isn’t loaded. That’s your root problem.
