How To Check if Ubuntu is Using Your NVIDIA Graphics Card

Ubuntu 7

In this article, we will guide you through the process of checking whether your Ubuntu system is utilizing your NVIDIA graphics card. This is an essential step for those who want to ensure their system is optimized for tasks that require high graphical processing power, such as gaming, 3D modeling, or video editing.

Quick Answer

To check if Ubuntu is using your NVIDIA graphics card, you can use the terminal command "lspci -vnnn | perl -lne ‘print if /^\d+:.+([\S+:\S+])/’ | grep VGA" to see the active graphics card. Additionally, you can check the OpenGL renderer by using the command "glxinfo|egrep ‘OpenGL vendor|OpenGL renderer*’" in the terminal. Alternatively, you can use the NVIDIA settings utility, the inxi package, or the nvtop tool to gather more detailed information about your graphics card.

Checking the Active Graphics Card

The first method to check the active graphics card involves using the terminal. Open a terminal by pressing Ctrl + Alt + T and type the following command:

lspci -vnnn | perl -lne 'print if /^\d+\:.+(\[\S+\:\S+\])/' | grep VGA

This command performs the following actions:

  • lspci lists all PCI devices.
  • -vnnn is an option that makes the output more verbose, showing all details.
  • The perl command is used to filter the output.
  • grep VGA filters the output to only show lines containing “VGA”.

The output will display a list of VGA compatible controllers. The device that has [VGA controller] at the end is the active GPU.

Checking the OpenGL Renderer

Another way to check if Ubuntu is using your NVIDIA graphics card is to check the OpenGL renderer. Type the following command in the terminal:

glxinfo|egrep "OpenGL vendor|OpenGL renderer*"

This command will show the OpenGL vendor and renderer information. If it displays NVIDIA Corporation as the vendor and your NVIDIA graphics card model as the renderer, then Ubuntu is using your NVIDIA GPU.

Using NVIDIA Settings Utility

The NVIDIA settings utility is a powerful tool that provides detailed information about the NVIDIA GPU. Open a terminal and type nvidia-settings. This will open the NVIDIA settings window. Here, you can see information about your GPU, such as the model, temperature, and usage.

Using the inxi Package

The inxi package is a full-featured system information script that provides detailed hardware and system information. Install it by running sudo aptitude install inxi in the terminal. After installation, use the command inxi -G to display detailed information about your graphics card.

Monitoring GPU Usage with nvtop

The nvtop tool is a htop-like GPU usage monitor. It provides real-time information about your GPU’s usage, memory, temperature, and fan speed. Run nvtop in the terminal to monitor your GPU usage. If you don’t have nvtop installed, you can install it by running sudo apt install nvtop.

Conclusion

Checking whether Ubuntu is using your NVIDIA graphics card is a straightforward process. However, if you encounter errors or the commands don’t provide the expected output, it could indicate that the NVIDIA driver is not installed or not functioning properly. In such cases, ensure you have the latest NVIDIA driver installed and running. You can download the driver from the NVIDIA website and follow the installation instructions specific to your GPU model.

By following the steps outlined in this article, you can ensure that your Ubuntu system is correctly utilizing your NVIDIA graphics card, allowing you to make the most of your system’s graphical processing capabilities.

How can I check if my Ubuntu system is using my NVIDIA graphics card?

To check if Ubuntu is using your NVIDIA graphics card, you can use the terminal command lspci -vnnn | perl -lne 'print if /^\d+\:.+(\[\S+\:\S+\])/' | grep VGA to list all VGA compatible controllers and identify the active GPU. Another method is to check the OpenGL renderer by running glxinfo|egrep "OpenGL vendor|OpenGL renderer*". You can also use the NVIDIA settings utility by typing nvidia-settings in the terminal or install the inxi package and use the command inxi -G to display detailed information about your graphics card.

How can I monitor the usage of my NVIDIA graphics card in Ubuntu?

You can monitor the usage of your NVIDIA graphics card in Ubuntu using the nvtop tool. Run nvtop in the terminal to get real-time information about GPU usage, memory, temperature, and fan speed. If nvtop is not installed, you can install it by running sudo apt install nvtop.

What should I do if the commands don’t provide the expected output?

If the commands don’t provide the expected output or you encounter errors, it could indicate that the NVIDIA driver is not installed or not functioning properly. In such cases, make sure you have the latest NVIDIA driver installed and running. You can download the driver from the NVIDIA website and follow the installation instructions specific to your GPU model.
