How to disable and remove Nvidia drivers on Ubuntu

Introduction

Nvidia drivers are essential for utilizing the full potential of your Nvidia graphics card on Ubuntu. They provide optimal performance, advanced features, and support for the latest games and applications. However, there might be situations where you need to disable or remove these drivers. Perhaps you're experiencing compatibility issues, troubleshooting a problem, or simply want to revert to the default Intel graphics driver. This article will guide you through the process of disabling and removing Nvidia drivers on Ubuntu, providing step-by-step instructions and troubleshooting tips.

Understanding Nvidia Drivers

Before we dive into the process, let's take a moment to understand the role of Nvidia drivers on Ubuntu.

The Importance of Drivers

Imagine a sophisticated machine like a car. It has a powerful engine, but without the proper driver, the engine can't communicate with the wheels, steering, and other components. The car won't move. Similarly, your Nvidia graphics card, a powerhouse for visual processing, needs the correct drivers to connect and communicate with your Ubuntu system.

Nvidia drivers act as the language translator between the graphics card and your system, enabling you to enjoy smooth visuals, high-performance gaming, and various other features.

Different Types of Nvidia Drivers

There are two main types of Nvidia drivers:

Proprietary drivers: These are the official drivers provided directly by Nvidia, offering the best performance and support. They are often referred to as the "recommended" drivers.
Open-source drivers: These are community-developed drivers based on the Nouveau project, offering a more open-source alternative. They may not be as feature-rich or as optimized as proprietary drivers, but they can still provide basic functionality.

Disabling Nvidia Drivers

Disabling Nvidia drivers temporarily allows you to use the default Intel graphics driver, which comes pre-installed with Ubuntu. This can be useful for troubleshooting, testing, or using applications that might not be compatible with Nvidia drivers.

Here are the steps to disable Nvidia drivers:

1. Identify the Installed Nvidia Driver:

Open a terminal window.
Run the command nvidia-smi to check the current driver version and other information about your Nvidia graphics card.

2. Remove the nvidia-settings package:

If you have the nvidia-settings package installed, you can remove it using the following command:

sudo apt-get purge nvidia-settings

This removes the Nvidia control panel and associated tools, ensuring no conflicts arise when switching to the default driver.

3. Modify the boot parameters:

Using the Grub Boot Menu:
- Restart your computer and press the Shift key during boot to access the Grub boot menu.
- Select the recovery mode option.
- Choose the "root" shell.
- Run the following commands to edit the boot parameters:
```
sudo mount /mnt/rootfs
sudo nano /etc/default/grub
```
- Locate the line starting with GRUB_CMDLINE_LINUX_DEFAULT and add nomodeset at the end, separated by a space. For instance:
```
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash nomodeset"
```
- Save the changes and exit the nano editor.
- Run the following commands to update Grub:
```
sudo update-grub
sudo reboot
```
Using the command line directly:
- Open a terminal window and run the following command to edit the boot parameters:
```
sudo nano /etc/default/grub
```
- Locate the line starting with GRUB_CMDLINE_LINUX_DEFAULT and add nomodeset at the end, separated by a space. For instance:
```
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash nomodeset"
```
- Save the changes and exit the nano editor.
- Run the following command to update Grub:
```
sudo update-grub
```
- Reboot your system.

4. Verify the Disablement:

After restarting, try to run an application that typically uses your Nvidia graphics card. If it doesn't work as expected, you've successfully disabled the Nvidia driver.

Removing Nvidia Drivers

If you want to completely remove Nvidia drivers from your Ubuntu system, follow these steps:

1. Identify and Remove Nvidia Packages:

Open a terminal window and run the following command to list all installed packages related to Nvidia:
```
apt-cache search nvidia
```
Use the output to identify and remove the relevant packages using the apt-get remove command. For example:
```
sudo apt-get remove nvidia-driver-470 nvidia-settings nvidia-prime 
```

2. Remove Nvidia Driver Files:

The above command removes the packages, but the driver files might still be present. You can delete these files manually.

3. Remove any lingering Nvidia Configuration Files:

If you have used the nvidia-settings tool to configure your graphics card, you might need to delete these configuration files from the ~/.config directory.

4. Purge the Nvidia Driver:

Use the purge option with the apt-get command to completely remove all configuration files related to the driver:
```
sudo apt-get purge nvidia*
```

Troubleshooting

You might encounter certain issues during the process of disabling or removing Nvidia drivers. Here are some troubleshooting steps:

Black Screen or No Display: If you encounter a black screen or no display after disabling or removing the Nvidia drivers, try booting into recovery mode and editing the boot parameters as described above.
Screen Resolution Issues: If you have screen resolution issues after disabling or removing the Nvidia drivers, you can try setting the resolution manually using the xrandr command.
Driver Conflicts: If you encounter driver conflicts, try using the apt-get autoremove command to remove any remaining driver files.
