How to Find Which Graphics Card do You Have in Linux?
|
||||
======
|
||||
|
||||
Be it [Nvidia][1] or [Radeon][2] 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
|
||||
|
||||
![][3]
|
||||
|
||||
#### Use lspci command to find graphics card
|
||||
|
||||
The lspci command displays the information about devices connected through [PCI][4] (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:
|
||||
|
||||
```
|
||||
lspci | grep VGA
|
||||
```
|
||||
|
||||
This should show a one line information about your graphics card:
|
||||
|
||||
```
|
||||
[email protected]:~$ lspci | grep VGA
|
||||
00:02.0 VGA compatible controller: Intel Corporation HD Graphics 620 (rev 02)
|
||||
```
|
||||
|
||||
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.
|
||||
|
||||
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:
|
||||
|
||||
```
|
||||
sudo lshw -C video
|
||||
```
|
||||
|
||||
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.
|
||||
|
||||
```
|
||||
[email protected]:~$ sudo lshw -C video
|
||||
[sudo] password for abhishek:

||||
*-display
|
||||
description: VGA compatible controller
|
||||
product: HD Graphics 620
|
||||
vendor: Intel Corporation
|
||||
physical id: 2
|
||||
bus info: [email protected]:00:02.0
|
||||
version: 02
|
||||
width: 64 bits
|
||||
clock: 33MHz
|
||||
capabilities: pciexpress msi pm vga_controller bus_master cap_list rom
|
||||
configuration: driver=i915 latency=0
|
||||
resources: irq:139 memory:db000000-dbffffff memory:90000000-9fffffff ioport:f000(size=64) memory:c0000-dffff
|
||||
```
|
||||
|
||||
#### 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][5], you can check the details by going to About section of Settings. Here’s what it looks like in [Ubuntu 20.04][6]:
|
||||
|
||||
![Graphics card information check graphically][7]
|
||||
|
||||
I hope you find this quick tip helpful. You can also use the same commands to [find your network adapter][8] and [CPU information in Linux][9].
|
||||
|
||||
If you have questions or suggestions, don’t hesitate to write a comment.

如何找出 Linux 中的显卡？
|
||||
======
|
||||
|
||||
无论是 [Nvidia][1] 还是 [Radeon][2] 或者 Intel，它们都可能在 Linux 中有问题。当你要对图形问题进行故障排除时，首先要了解系统中装有哪种显卡。
|
||||
|
||||
Linux 有几个命令可以检查硬件信息。你可以使用它们来检查你有哪些显卡（也称为视频卡）。让我向你展示一些命令来获取 Linux 中的 GPU 信息。
|
||||
|
||||
### 在 Linux 命令行中检查显卡详细信息
|
||||
|
||||
![][3]
|
||||
|
||||
#### 使用 lspci 命令查找显卡
|
||||
|
||||
lspci 命令显示通过 [PCI][4]（外设组件互连）总线连接的设备的信息。基本上，此命令提供有关系统所有外设的详细信息，从键盘和鼠标到声卡、网卡和显卡。
|
||||
|
||||
默认情况下，你会有大量的此类外设列表。这就是为什么你需要用 grep 命令过滤显卡的原因：
|
||||
|
||||
```
|
||||
lspci | grep VGA
|
||||
```
|
||||
|
||||
这应该会显示一行有关你显卡的信息：
|
||||
|
||||
```
|
||||
[email protected]:~$ lspci | grep VGA
|
||||
00:02.0 VGA compatible controller: Intel Corporation HD Graphics 620 (rev 02)
|
||||
```
|
||||
|
||||
如你所见，我的系统中有 Intel HD 620 显卡。
|
||||
|
||||
#### 在 Linux 中使用 lshw 命令获取显卡详细信息
|
||||
|
||||
lspci 命令足以查看你的显卡，但是并不能告诉你很多信息。你可以使用 lshw 命令获取有关它的更多信息。
|
||||
|
||||
此命令要求你有 root 用户权限。你需要以这种方式查找视频卡（显卡）信息：
|
||||
|
||||
```
|
||||
sudo lshw -C video
|
||||
```
|
||||
|
||||
正如你在下面的输出中看到的那样，此命令提供了有关显卡的更多信息，例如时钟频率、位宽、驱动等。
|
||||
|
||||
```
|
||||
[email protected]:~$ sudo lshw -C video
|
||||
[sudo] password for abhishek:

description: VGA compatible controller
|

|

|

physical id: 2
|
||||
bus info: [email protected]:00:02.0
|
||||
version: 02
|
||||
width: 64 bits
|
||||
clock: 33MHz
|
||||
capabilities: pciexpress msi pm vga_controller bus_master cap_list rom
|
||||
configuration: driver=i915 latency=0
|
||||
resources: irq:139 memory:db000000-dbffffff memory:90000000-9fffffff ioport:f000(size=64) memory:c0000-dffff
|
||||
```
|
||||
|
||||
#### 额外的技巧：以图形方式检查显卡详细信息
|
||||
|
||||
并非必须使用命令行在 Linux 中查找显卡详细信息。大多数 Linux 发行版（或者应该说是桌面环境）在设置中提供了必要的详细信息。
|
||||
|
||||
例如，如果你使用的是 [GNOME 桌面环境][5]，那么可以进入“设置”的“关于”部分来检查详细信息。[Ubuntu 20.04][6] 中看上去像这样：
|
||||
|
||||
![Graphics card information check graphically][7]
|
||||
|
||||
我希望这个快速技巧对你有所帮助。你也可以使用相同的命令来[查找网卡][8]和 [Linux 中的 CPU 信息][9]。
|
||||
|
||||
如果你有任何疑问或建议，请随时发表评论。
