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
