Overview of the NVIDIA GPU Recognition Issue on Ubuntu 24.04.02

Many users report that after upgrading or installing Ubuntu 24.04.02, the NVIDIA GPU is not automatically recognized. This issue has been widely discussed across multiple platforms, and the primary concerns revolve around driver incompatibility, improper installation, and system configurations that conflict with NVIDIA’s proprietary drivers. In systems equipped with both integrated (Intel/AMD) and discrete NVIDIA GPUs, Ubuntu might default to the integrated solution, causing the dedicated NVIDIA card to remain undetected. Moreover, legacy GPU models may not be supported by the new drivers shipped with Ubuntu 24.04.02, and kernel updates can further complicate the matter.

Detailed Diagnostic Steps and Solutions

1. Verify Driver Installation

Check Current Driver Status

Begin your troubleshooting by verifying if the NVIDIA drivers are properly installed:

# Check NVIDIA driver status
nvidia-smi

If you encounter an error message stating "NVIDIA-SMI has failed because it couldn't communicate with the NVIDIA driver," it is an indicator that the drivers may either be incorrectly installed or incompatible with your GPU model.

Install or Reinstall Drivers

It is crucial to install the correct NVIDIA driver version for your GPU. Ubuntu’s "Additional Drivers" tool often helps automate this process. Alternatively, you can use the following commands to automatically install the recommended drivers:

sudo apt update
sudo apt upgrade
sudo ubuntu-drivers autoinstall

You may need to reboot after installation:

sudo shutdown -r now

If this method does not yield results, consider purging previous NVIDIA packages and reinstalling them. This involves switching temporarily to the Nouveau driver, purging all NVIDIA-related packages, and then reinstalling from the "Software & Updates" configuration.

2. Addressing Secure Boot and Kernel Compatibility

Secure Boot and BIOS Settings

Modern Ubuntu installations may have Secure Boot enabled in the BIOS, which can prevent unsigned drivers, such as those from NVIDIA, from loading correctly. Enter your BIOS settings (often accessible by pressing F2, Esc, or Del during system startup) and disable Secure Boot. Additionally, verify that the BIOS is configured to prioritize the dedicated GPU if you have a system with both integrated and discrete graphics.

Kernel Version Issues

An unsupported or recently updated kernel can also lead to driver incompatibility. Identify your current kernel version by running:

uname -r

If you suspect that a recent kernel update might be incompatible with your NVIDIA drivers, consider booting with an older, stable kernel version available in your GRUB menu. Some users have reported success reverting to a prior kernel when experiencing detection issues.

3. Configuration Adjustments and Advanced Fixes

Blacklisting the Nouveau Driver

In some cases, the open-source Nouveau driver may interfere with the proper functioning of NVIDIA’s proprietary driver. To prevent this interference, blacklist the Nouveau driver by creating a configuration file:

sudo bash -c "echo blacklist nouveau > /etc/modprobe.d/blacklist-nouveau.conf"

After making this change, update your GRUB configuration and reboot the system.

NVIDIA X Server Settings & PRIME Profiles

For laptops or systems with hybrid graphics, use the NVIDIA X Server Settings tool to adjust PRIME Profiles. If the system is defaulting to the integrated GPU, switch the profile to "NVIDIA (Performance Mode)" to enforce the use of the discrete NVIDIA GPU. Also, check the PowerMizer settings ensuring they are set to "Auto" to allow dynamic performance scaling.

Manual Installation of NVIDIA Drivers

In cases where the automatic installation does not work, consider manually installing the drivers. Download the latest driver from the official NVIDIA website. Before running the installer:

Disable Secure Boot.
Edit your GRUB configuration to include "nomodeset" by modifying the file /etc/default/grub and updating GRUB.

Boot into Recovery Mode, enable networking, navigate to the directory containing the downloaded .run file, and execute it with administrative privileges.

sudo bash ./NVIDIA-Linux-x86_64-xxx.xx.run
