How To Fix Black Screen at Boot After Nvidia Driver Installation on Ubuntu 18.04.2 LTS

Ubuntu 8

In this article, we will explore how to fix the black screen issue that arises after installing the Nvidia driver on Ubuntu 18.04.2 LTS. This problem can be quite frustrating, but with the right steps, it can be resolved.

Quick Answer

To fix the black screen issue at boot after Nvidia driver installation on Ubuntu 18.04.2 LTS, you can try accessing the terminal using the shortcuts Ctrl + Alt + F1 through Ctrl + Alt + F6. If that doesn’t work, you can try accessing it through the GRUB menu by adding nouveau.modeset=0 or nomodeset to the boot options. If these methods don’t work, you may need to reinstall the Nvidia driver by removing existing drivers, adding the graphics-drivers PPA, updating the package list, and installing the correct Nvidia driver for your graphics card.

Understanding the Problem

The black screen issue usually occurs when there is an incompatibility between the Nvidia driver and your graphics card. This can happen when the driver is not properly installed or when the wrong driver is installed.

Accessing the Terminal

Before we start, it is important to know how to access the terminal if your screen is black. You can do this by pressing Ctrl + Alt + F1. If this doesn’t work, try Ctrl + Alt + F2 through Ctrl + Alt + F6.

In case you are unable to access the terminal using these shortcuts, you can try accessing it through the GRUB menu. To do this:

  1. Highlight the Ubuntu option in the GRUB menu and press E.
  2. Add nouveau.modeset=0 to the end of the line beginning with linux.
  3. Press F10 to boot.

If this doesn’t work, you can replace quiet splash with nomodeset in the GRUB menu and boot with F10.

Reinstalling the Nvidia Driver

If the above steps do not resolve the issue, you may need to reinstall the Nvidia driver.

To remove any existing Nvidia drivers, open a terminal and run the following command:

sudo apt-get purge nvidia*

This command will remove all installed Nvidia packages. The sudo command is used to execute the command as a superuser, apt-get is the package handling utility in Ubuntu, and purge is used to remove packages and their configuration files.

Next, add the graphics-drivers PPA by running:

sudo add-apt-repository ppa:graphics-drivers/ppa

This command adds the Personal Package Archive (PPA) for graphics drivers to your system.

After adding the PPA, update the package list by running:

sudo apt-get update

This command updates the list of packages and their versions on your system.

Now, install the correct Nvidia driver. For example, if the correct driver for your graphics card is Nvidia-410, you would run:

sudo apt-get install nvidia-410

This command installs the Nvidia-410 driver. Replace nvidia-410 with the correct version for your graphics card.

Finally, reboot your system by running:

sudo reboot

Verifying the Installation

After rebooting, you can check if the installation was successful by running the following command:

lsmod | grep nvidia

If there is output, then the installation was successful. The lsmod command shows the status of modules in the Linux Kernel and grep is used to filter the output for the term ‘nvidia’.

Conclusion

Remember to always check the compatibility of the Nvidia driver with your graphics card before installing it. Blindly following instructions without considering compatibility can lead to issues like the black screen problem you encountered.

If you are unable to access a terminal or the GRUB menu, you may need to seek further assistance or consider reinstalling Ubuntu.
