How to Find Which Graphics Card do You Have in Linux?

Last updated April 18, 2020 By Abhishek Prakash 19 Comments

Be it Nvidia or Radeon or Intel, they all may have some issues with Linux. When you are on your way to troubleshoot the graphics problem, the first thing you want to know is which graphics card do you have in your system.

Linux has several commands to check hardware information. You can use them to check what graphics card (also refer to as video card) do you have. Let me show you a couple of commands to get GPU information in Linux.

Check graphics card details in Linux command line

Use lspci command to find graphics card

The lspci command displays the information about devices connected through PCI (peripheral Component Interconnect) buses. Basically, this command gives you the detail about all the peripheral devices to your system from keyboard and mouse to sound, network and graphics cards.

By default, you’ll have a huge list of such peripheral devices. This is why you need to filter the output for graphics card with grep command in this manner:

This should show a one line information about your graphics card:

As you can see, my system has Intel HD 620 video card.

Get detailed graphics card information with lshw command in Linux

The lspci command is good enough to see what graphics card you have but it doesn’t tell you a lot. You can use lshw command to get more information on it.

You may have to install lshw on Fedora, Manjaro and a few non-Ubuntu distributions.

This command requires you to have root access. You need to specify that you are looking for video card (graphics card) information in this fashion:

And as you can see in the output below, this command gives more information on the graphics card such as clock rate, width, driver etc.

Bonus Tip: Check graphics card details graphically

It’s not that you must use the command line to find graphics card details in Linux. Most Linux distributions (or should I say desktop environments) provide essential details in the settings application.

For example, if you are using GNOME desktop environment, you can check the details by going to About section of Settings. Here’s what it looks like in Ubuntu 20.04:

I hope you find this quick tip helpful. You can also use the same commands to find your network adapter and CPU information in Linux.

If you have questions or suggestions, don’t hesitate to write a comment.

2 Tools For Monitoring Nvidia GPUs On Linux (GUI And Command Line)

This article presents 2 tools for monitoring Nvidia graphics cards on Linux: one that comes with a terminal user interface (TUI), so it runs in a console, and another one that uses a graphical user interface.

These utilities to monitor Nvidia GPUs require using the proprietary Nvidia graphics drivers.

nvtop — terminal user interface to monitor Nvidia GPUs

nvtop is a (h)top like task monitor for Nvidia GPUs. It uses the ncurses to draw its text-based user interface in the terminal, and it makes use of the NVIDIA Management Library (NVML) to get the GPU information.

Since it uses NVML, this command line tool doesn’t support older Nvidia GPUs. GeForce 600, GeForce 800M, and newer should work, but older GPUs are not supported.

• supports multiple GPUs
• shows a list of processes running on the Nvidia GPU, their name, pid, their utilization of GPU, memory and CPU, etc. The processes can be sorted and killed from nvtop
• shows a graph of GPU and memory utilization
• shows current (live) GPU and memory utilization and frequency, fan speed, power usage, and temperature

nvtop was recently added to the Ubuntu 19.04+, and Debian buster and sid (contrib) repositories. But if you want to use it with drivers that aren’t in the repositories (e.g. if you use newer drivers), it won’t install because it depends on the specific drivers version that’s in the repositories. In that case install it from source, it’s quite easy.

The nvtop README has instructions for building the tool from source (including the required dependencies) for Debian / Ubuntu, Fedora / RedHat / CentOS, openSUSE and Arch Linux.

Nvidia System Monitor GUI for Linux

Nvidia System Monitor Qt is a new graphical tool to see a list of processes running on the GPU, and to monitor the GPU and memory utilization (using graphs) of Nvidia graphics cards. It makes use of the nvidia-smi tool to get the GPU information.

This Nvidia task manager for Linux is only 12 days old, so it still needs some work. The developer says other functions, like the ability to monitor the Nvidia GPU temperature, making the program available in other languages, and more, will be added in the next versions.

Nvidia System Monitor features:

• Processes: shows a list of processes running on the GPU, with the process name, pid, used memory, and more
• Utilization:
  • GPU: shows a graph of the GPU utilization, while also showing the average, minimum and maximum GPU utilization
  • Memory: shows the Nvidia GPU memory utilization, while also showing the average, minimum and maximum memory utilization. You can also see here the total, free and used GPU memory.

By default, Nvidia System Monitor is updated every 2 seconds (2000 ms). If you want to change this, create a file called config in the

/.config/nvidia-system-monitor folder, and add updateDelay followed by the time in ms to this file. For example, use updateDelay 500 to have NVIDIA System Monitor update every 500 ms (0.5 seconds).

To install NVIDIA System Monitor, you’ll need to install its build dependencies. Also install Git to get the latest code of the application from Git In Debian, Ubuntu or Linux Mint, install these packages using:

To get Nvidia System Monitor from Git, build and install it, use:

The application is now installed but unfortunately it does not have a .desktop file, so it will not be displayed in your applications menu. Launch it using Alt + F2 or by opening a terminal and typing qnvsm . You can createa .desktop file for it yourself if you wish.

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

The reason I’m asking is that none of the games I’ve installed through software center that require 3D accelartion like TORCS for instance will run. When I try to run then, nothing happens. I have a Dell Inspiron N5110 with a nVidia GeForce GT 525M.

I tried the following which I were some suggestions for people with similar problems:

I don’t really understand what all this means.

I know the question is old, but I found a solution which I haven’t found on any other topic.

Open a terminal and type

Your output will be something like that:

Now look for the [VGA controller] at the end of each device. Whichever device has it, is the active GPU. In my case it’s the i7 processor (HD 4000) that’s handling the work.

I found this (if you have NVidia and intel graphic cards):

I think the following command should give you an indication of your active chip:

If you switched to NVidia card:

nvidia-settings utility

On Ubuntu 15.10, after I installed nvidia-352 and the GPU seems to work (see e.g. these steps):

shows something like:

Note how it shows:

where NVS 5400M is my GPU model. Also tested on a Quadro K1100M . This did not show up before I had installed the driver.

the GPU usage goes to > 90%, further sign that it is working.

But in the end, the only test that matters is to do a benchmark with / without GPU and see your FPS goes way up or not: How to perform a detailed and quick 3D performance test

NVTOP Options and Interactive Commands

Interactive Setup Window

NVTOP has a builtin setup utility that provides a way to specialize the interface to your needs. Simply press F2 and select the options that are the best for you.

You can save the preferences set in the setup window by pressing F12 . The preferences will be loaded the next time you run nvtop .

NVTOP Manual and Command line Options

NVTOP comes with a manpage!

For quick command line arguments help

The NVML library does not support some of the queries for GPUs coming before the Kepler microarchitecture. Anything starting at GeForce 600, GeForce 800M and successor should work fine. For more information about supported GPUs please take a look at the NVML documentation.

Two libraries are required in order for NVTOP to display GPU information:

• The NVIDIA Management Library (NVML) which comes with the GPU driver.
  • This queries the GPU for information.
• The ncurses library driving the user interface.
  • This makes the screen look beautiful.

Distribution Specific Installation Process

Ubuntu disco (19.04) / Debian buster (stable)

• NVIDIA drivers (see Ubuntu Wiki or Ubuntu PPA or Debian Wiki)
• CMake, ncurses and git

Fedora / RedHat / CentOS

• NVIDIA drivers, CUDA required for nvml libraries (see RPM Fusion)
• CMake, ncurses and git

• NVIDIA drivers (see SUSE Support Database)
• CMake, ncurses and git

NVIDIA drivers (same as above)

If you use conda as environment manager and encounter an error while building nvtop, try conda deactivate before invoking cmake .

The build system supports multiple build type (e.g. -DCMAKE_BUILD_TYPE=RelWithDebInfo):

• Release: Binary without debug information
• RelWithDebInfo: Binary with debug information
• Debug: Compile with warning flags and address/undefined sanitizers enabled (for development purposes)

• The plot looks bad:
  • Verify that you installed the wide character version of the NCurses library (libncursesw5-dev for Debian / Ubuntu), clean the build directory and restart the build process.
• Putty: Tell putty not to lie about its capabilities ( $TERM ) by setting the field Terminal-type string to putty in the menu Connection > Data > Terminal Details .

Nvtop is licensed under the GPLV3 license or any later version. You will find a copy of the license inside the COPYING file of the repository or at the gnu website .
