How do I find out the model of my graphics card?

Open up "Terminal", and type: lspci | grep VGA

There, you'll find your GPU card's model.

For detailed information about your graphics card, usually including its make and model, run:

sudo lshw -C video

This might give the make and model name more often than lspci, but it is not guaranteed to give it (nor is lspci).

sudo lshw -C display is equivalent.

You can run this (either one) without sudo, but you're a little less likely to get as much information. Still, lshw -C video is a reasonable choice if you don't have administrative powers.

If you like, you can parse the output to get just the line with the model name:

sudo lshw -C video | grep product:

Or if you need to extract just the name (for example, for scripting purposes--but remember there isn't always anything to extract):

sudo lshw -C video | awk -F'product: ' '/product/{print $2}'

(Don't forget the space just after -Fproduct:, before the closing '.)

As an example: on my system, this gives:

M52 [Mobility Radeon X1300]

Sometimes lspci is not enough:

$ lspci -nn |egrep "VGA|Display" 

e.g.: you can end up with something like this:

00:02.0 VGA compatible controller [0300]: Intel Corporation 4 Series Chipset Integrated Graphics Controller [8086:2e32] (rev 03)

so then you can try to grep Xorg log:

$ grep -i chipset /var/log/Xorg.0.log

and dmesg

$ dmesg |grep -i agp

1. run gnome-control-center (from a terminal, or in the main menu system settings)
2. search for 'system' and open "System Info"
3. You are done.

If GUI/display available, you can try:

xrandr --listproviders

(Other answers where either only giving a chipset range or no manufacturer info for my AMD card.)

To get exact chipset model, video memory, and drivers info:

glxinfo -B

To get card manufacturer name:

hwinfo --gfxcard | grep SubVendor

Ubuntu 20.04 Settings -> About

You can either open settings by clicking as mentioned at: https://askubuntu.com/a/1144742/52975 but I just do:

• Super key (AKA Windows key)
• Type "about" and select the entry

So under "Graphics" I can see that my GPU model is "Quadro M1200/PCIe/SSE2".

nvidia-settings

Mixes runtime with some static info.

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

In KDE you can use the kinfocenter (open a command prompt from a graphical environment and type that, or type it at the K-menu [application menu] prompt; or navigate to K → Computer → Info Center ... ).

Personally I use lshw or lspci as in other answers, but another possibility is :

glxinfo | grep Device

Which maybe only works if your device is using OpenGL, not sure, but for me this gives:

    Device: AMD KAVERI (DRM 3.27.0, 5.0.0-15-generic, LLVM 8.0.0) (0x1313)

which is quite neat. The second number is the kernel version, fwiw.

If you want to detect your graphic card from Ubuntu Desktop, try this:

1. Click on User menu at the top right corner on the top Menu bar
2. Select System Settings
3. Click on Details.
4. By default you should see your graphic information. Take look at this example image.

Note: This answer was done in Ubuntu 16.04 LTS version.

The command line tool called inxi will show You:

inxi -Gx
Graphics:  Device-1: NVIDIA GP104 [GeForce GTX 1080] vendor: ASUSTeK driver: nvidia v: 435.21 bus ID: 01:00.0
