ubuntu下如何查看显卡及显卡驱动

使用nvidia-smi 工具查看

查看显卡型号nvida-smi -L

$ nvidia-smi -L
GPU 0: NVIDIA GeForce RTX 3050 4GB Laptop GPU (UUID: GPU-4cf7b7cb-f103-bf56-2d59-304f8996e28c)

当然直接使用nvida-smi 命令可以查看更多信息

$ nvidia-smi

注意，上图中的 CUDA Version 后面写了一个版本号。该版本号并不是你已经安装了该版本的 CUDA 的意思，而是说此显卡最大支持的CUDA版本号。因此我们仍然需要手动从官网下载CUDA，且版本号不能高于这个。

还可以使用如下命令，查看显卡驱动版本

$ cat /proc/driver/nvidia/version
NVRM version: NVIDIA UNIX x86_64 Kernel Module  535.154.05  Thu Dec 28 15:37:48 UTC 2023
GCC version:  gcc version 12.3.0 (Ubuntu 12.3.0-1ubuntu1~22.04)

也可以使用navidia-settings命令弹出图形界面

$ navidia-settings

安装显卡前查看推荐的显卡

当然，如果没安装显卡驱动，则需要安装驱动，可使用如下命令

首先我们需要看看显卡硬件有没正确安装到计算机，我们可以通过命令lspci查看一下

$ lspci

使用ubuntu-drivers devices命令，查看所有可用的即推荐的显卡驱动

$ ubuntu-drivers devices

nvidia-driver-535 - distro non-free recommended 这个即推荐的
使用sudo ubuntu-drivers autoinstall可直接安装推荐的显卡
也可使用sudo apt-get install nvidia-driver-525 制定版本安装

关于ubuntu下的显卡驱动安装详细过程，可以点击这里

用nvidia-detector 命令，可查看支持的最高版本驱动

$ nvidia-detector 
nvidia-driver-545
