How to find out which NVIDIA GPU I have

I’m trying to use the information in this page to optimize my GPU performance. For that, I need to know which NVIDIA GPU I have. I tried the command sudo lshw -C display and I’m getting the following output which is not very helpful:

If you have it installed, you can also use nvidia-smi which provides even more information for NVIDIA GPUs (this is, after all, what they use in the page you linked):

$ nvidia-smi Mon Sep 15 16:02:31 2014 +------------------------------------------------------+ | NVIDIA-SMI 340.32 Driver Version: 340.32 | |-------------------------------+----------------------+----------------------+ | GPU Name Persistence-M| Bus-Id Disp.A | Volatile Uncorr.

If you just want the GPU name:

$ nvidia-smi --query-gpu=name --format=csv,noheader GeForce GT 650M

Как узнать видеокарту в Linux

Растущая популярность Linux и основанных на нём игровых платформ, таких как Steam, увеличивает количество выпущенных для этой операционной системы игр с каждым годом. Если вы геймер, то скорее всего уделяете много внимания производительности видеокарты в системе.

Многие из вас, наверное, готовы выложить несколько тысяч рублей за хорошую видеокарту, чтобы добиться максимальной производительности. В этой инструкции я расскажу, как посмотреть информацию о видеокарте и видео драйвере в системе Linux.

Как посмотреть видеокарту в Linux

1. lspci

Видеокарта подключена к материнской плате через PCI слот. Следовательно, вы можете определить видеокарту с помощью консольной утилиты lspci, которая позволяет увидеть все PCI-устройства. Если вы пользуетесь командой lspci в первый раз нужно обновить базу данных PCI-устройств:

Теперь используйте следующую команду, чтобы узнать производителя и название видеокарты:

После того как вы узнаете PCI-порт видеокарты, например 1с:00.0, можно получить о ней более подробную информацию:

Здесь мы видим, что производитесь видеокарты Zotac, а в качестве видео драйвера используется nouveau.

2. lshw

Следующий способ узнать информацию о видеокарте — это использовать утилиту lshw.

Тут мы видим почти те же данные, название модели видеокарты, служебную информацию и используемый видеодрайвер.

3. glxinfo

Информацию про видеокарту можно вывести с помощью glxinfo. Утилита входит в набор программ mesa-utils, поэтому сначала нужно его установить:

sudo apt install mesa-utils

Затем смотрим информацию, здесь она не такая подробная:

Зато glxinfo позволяет посмотреть количество памяти, доступное видеокарте:

glxinfo | egrep -i ‘device|memory’

В данном случае, это модель видеокарты с 3 Гб встроенной памяти.

4. hardinfo

Ещё можно посмотреть информацию о видеокарте в программе Hardinfo. Для установки Hardinfo в Debian, Ubuntu, Linux Mint используйте команду:

sudo apt install hardinfo

Запустить установленную программу можно, выполнив:

Откройте Устройства -> Устройства PCI -> VGA compatible controller, чтобы посмотреть данные о видеокарте:

5. Параметры системы

Утилита Параметры системы в Gnome тоже выводит информацию о процессоре и графической карте. Для этого откройте Сведения о системе -> О приложении:

Как узнать видео драйвер

Чтобы узнать название используемого видеодрайвера, можно запустить lshw:

sudo lshw -c video | grep driver

Имя драйвера находится после строчки driver=имя_драйвера, например noeveau или nvidia. Как я уже писал выше, у меня используется свободный драйвер. Детальную информацию можно посмотреть командой:

Здесь выводится название драйвера, его производитель, а также версия. Для проприетарного драйвера информации может быть меньше, но она будет структурирована похожим образом.

Обнаружили ошибку в тексте? Сообщите мне об этом. Выделите текст с ошибкой и нажмите Ctrl+Enter.

How to get information about graphics card (GPU) on Linux

You need to find out the correct model and vendor of the graphics card on your system, to be able to install the appropriate drivers and get the hardware to function properly. Most modern linux distros can detect variety of graphics card, but do not always have the best driver for it.

So if you have an external graphics card like Nvidia or Ati, then you need to find the model name/number and then lookup further details online. Ofcourse, its easier if you have the hardware manual that came along when you purchased the computer. But here we shall be using commands to find out the same information.

Hardware details

The are only a few commands to learn. First one is lscpi and here is a quick example showing how to fetch details about graphics unit (also called vga card or video card).

$ lspci -vnn | grep VGA -A 12 00:02.0 VGA compatible controller [0300]: Intel Corporation 82G35 Express Integrated Graphics Controller [8086:2982] (rev 03) (prog-if 00 [VGA controller]) Subsystem: Intel Corporation Device [8086:d701] Flags: bus master, fast devsel, latency 0, IRQ 44 Memory at e0200000 (32-bit, non-prefetchable) [size=1M] Memory at d0000000 (64-bit, prefetchable) [size=256M] I/O ports at 2440 [size=8] Expansion ROM at [disabled] Capabilities: Kernel driver in use: i915

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

VGA compatible controller [0300]: Intel Corporation 82G35 Express Integrated Graphics Controller [8086:2982]

Note the numbers in the bracket — 8086:2982. Such a number is present for almost all graphics card. The first part (8086) indicates the vendor id (which is Intel here) and the second number (2982) indicates the pci id, which indicates the model of the graphics unit.

Now you can search google for more details using the Vendor name and the pci id.

The lshw command can also be used to get the above information.

$ lshw -numeric -C display WARNING: you should run this program as super-user. *-display:0 description: VGA compatible controller product: 82G35 Express Integrated Graphics Controller [8086:2982] vendor: Intel Corporation [8086] physical id: 2 bus info: [email protected]:00:02.0 version: 03 width: 64 bits clock: 33MHz capabilities: vga_controller bus_master cap_list rom configuration: driver=i915 latency=0 resources: irq:44 memory:e0200000-e02fffff memory:d0000000-dfffffff ioport:2440(size=8)

The pci details is indicated in the same way. The active device driver is also listed in the «configuration» line.

Here is a sample output from a system having an nvidia geforce 210 graphics card.

$ lspci -vnn | grep VGA -A 12 01:00.0 VGA compatible controller [0300]: NVIDIA Corporation GT218 [GeForce 210] [10de:0a65] (rev a2) (prog-if 00 [VGA controller]) .

Integrated chipsets vs dedicated gpus

For dedicated units like nvidia or ati, you can easily search online for the model number or pci id. The specifications and other details would be available on the vendor’s website.

However for integrated graphics chipsets like Intel GMA, you may not get sufficient details by just searching the series name (82G35 over here) or pci id. The series covers many similar models, while the pci id might not be documented on the website.

In that case, lookup the motherboard model and find its specifications. Vendors publish product specification documents for every motherboard model they manufacture. These contain technical details about the hardware.

To find your motherboard model, use dmidecode or inxi command.

$ sudo dmidecode -t baseboard | grep -i 'Product' Product Name: DG35EC

$ inxi -M Machine: Mobo: Intel model: DG35EC version: AAE29266-210 Bios: Intel version: ECG3510M.86A.0112.2009.0203.1136 date: 02/03/2009

The above output shows that its a «Intel DG35EC» motherboard. Google up for that model to find the product specifiation document, and look for Video/Graphics information in it.

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, speeding up 3d rendering significantly. For this, the graphics card must support hardware acceleration and the correct drivers must be installed on the system to use this feature.

The 3d processing functions provided by the hardware adhere to the OpenGL specifications, and with the right hardware, applications can access them through the opengl api. OpenGL just defines the functions and the implementation is done inside the hardware which makes it very fast.

However there are libraries like MESA that implement the opengl functions entirely inside software. So it is possible to render graphics using opengl without actually having an opengl compatible gpu. So by checking the opengl rendering library, we can find out if hardware acceleration is present or not.

Check the glxinfo command output for OpenGL details

$ glxinfo | grep OpenGL OpenGL vendor string: Intel Open Source Technology Center OpenGL renderer string: Mesa DRI Intel(R) 965G OpenGL version string: 2.1 Mesa 10.1.0 OpenGL shading language version string: 1.20 OpenGL extensions:

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 would not work well.

The output on a machine with dedicated nvidia geforce 200 graphics card looks like this

$ glxinfo | grep OpenGL OpenGL vendor string: NVIDIA Corporation OpenGL renderer string: GeForce 210/PCIe/SSE2 OpenGL core profile version string: 3.3.0 NVIDIA 331.20 OpenGL core profile shading language version string: 3.30 NVIDIA via Cg compiler OpenGL core profile context flags: (none) OpenGL core profile profile mask: core profile OpenGL core profile extensions: OpenGL version string: 3.3.0 NVIDIA 331.20 OpenGL shading language version string: 3.30 NVIDIA via Cg compiler

OpenGL renderer string: GeForce 210/PCIe/SSE2

So the OpenGL renderer is GeForce, which is the nvidia proprietory driver. This indicates the hardware based 3d acceleration is available. So graphics performance would be good.

How to check which GPU is active in Linux?

I’ve just gone through a hell of a time trying to get my discrete graphics to work in Ubuntu and answering this questions was constantly a challenge, since the lspci method mentioned earlier can sometimes say that both are [VGA controller]

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

$ glxinfo|egrep "OpenGL vendor|OpenGL renderer" OpenGL vendor string: Intel Open Source Technology Center OpenGL renderer string: Mesa DRI Intel(R) Sandybridge Mobile 

For me this is telling me that my intel graphics are running the show.

glxinfo is availible from the mesa-utils package, so you will need to install it if you haven’t already. On Ubuntu 22.04 for example, run:

sudo apt-get install mesa-utils 

If you’re using an nvidia chip, and you’re using the bumblebee package, you can put optirun in front of that line and it should tell you that you’re running the NVidia chip (optirun is basically telling the computer to use the discrete chip to run whatever command follows, but everything else is still using the integrated chip)

$ optirun glxinfo|egrep "OpenGL vendor|OpenGL renderer" OpenGL vendor string: NVIDIA Corporation OpenGL renderer string: GeForce GT 555M/PCIe/SSE2 

glxheads is another helpful command from mesa-utils that tells you some useful information about which graphics card is in use (mostly repeats glxinfo in a more compact and easy to read form tho), and it gives you a nice rendering of a rotating triangle.
