How to Get Graphics Card Information on Linux

A graphics processing unit (GPU), also known as visual processing unit (VPU), is a specialized electronic circuit designed to rapidly manipulate and alter memory to accelerate the creation of images in a frame buffer intended for output to display. If you want to install the appropriate graphics card driver and get the graphics card to function properly, then you need to find the correct model and vendor of the graphics card on your system. Most Linux distributions can detect varieties of graphics cards but do not always have the best drivers for them. So if you have an external graphics card like Nvidia, then you need to find the model name/number and then look up further details.

In this article we will explain how to get graphics card information using the command line.

Get Hardware Details

There are only a few commands to get hardware information; lspci is one of the command line tools that fetches details about the graphics card.

Run the following command to get the graphics card information on your system.

You will see it output sonething like this:

The first line has the name of the vendor, the model name/series and the pci id.

Note the numbers in the bracket: 8086:0f31 . Such a number is present for almost all graphics cards. The first part, 8086, indicates the vendor id (which is Intel here) and the second number, 0f31, indicates the pci id, which indicates the model of the graphics unit.

You can also use the lshw command to get the above information.

Run the lshw command on your system.

You will see the following output:

Find What Graphics Card Driver Is Used on Linux

To identify the name of the graphics card driver used on your system, you can use the lshw command shown below.

You wI’ll see it output something like this:

The name of the graphics card driver is shown in driver=i915 . After, you can check the details of the graphics card driver as follows:

You will see it output something like this:

Check Hardware Acceleration

With hardware-based 3d acceleration, applications that need to draw 3d graphics can use the hardware directly to process and generate the graphics and speed up 3d rendering significantly. For this, the graphics card must support hardware acceleration, and the correct drivers must be installed on your system.

You can use the glxinfo command to get the details of OpenGL:

You will see an output like this:

The OpenGL renderer string points to MESA libraries which means that 3d rendering is being handled entirely inside software. This is going to be slow, and games wI’ll not work well.

Conclusion

I hope you now have enough knowledge to find the correct information of the graphics card installed on your system and that you can easily install the correct diver for the graphics card. Feel free to comment if you have any questions.

One comment

You can also use “inxi -G” to display all the info about the graphics card with one command. Other options control how verbose the display is.

“inxi” is a very powerful command line tool that will detect a lot of information about your installed hardware. “inxi” is installed by default with some Linux/BSD distros. It is available in the repositories of most Linux/BSD distros and can be installed just as any other package.

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.
