Ubuntu20.04 Linux 5.4.0-62 安装Cuda10.2
一、安装系统推荐NVIDIA显卡驱动
方法1. 安装系统推荐NVIDIA显卡驱动(通常为最新版本)
- 1.1 查看显卡名称及系统推荐驱动
sudo add-apt-repository ppa:graphics-drivers #添加NVIDA显卡驱动库
sudo apt update
ubuntu-drivers devices #显示可安装驱动
运行结果如下图示：
root@labLab:/home/user1/work# ubuntu-drivers devices
== /sys/devices/pci0000:00/0000:00:01.1/0000:02:00.0 ==
modalias : pci:v000010DEd00001E04sv00001458sd000037C0bc03sc00i00
vendor : NVIDIA Corporation
model : TU102 [GeForce RTX 2080 Ti]
manual_install: True
driver : nvidia-driver-440-server - distro non-free
driver : nvidia-driver-455 - third-party free
driver : nvidia-driver-418-server - distro non-free
driver : nvidia-driver-460 - third-party free recommended # 系统推荐版本
driver : nvidia-driver-450-server - distro non-free
driver : xserver-xorg-video-nouveau - distro free builtin
1.2 运行下示命令安装
# 安装系统推荐版本
sudo ubuntu-drivers autoinstall
or
# 手动指定版本安装
sudo apt install nvidia-driver-455
1.3 重启并查看
# 重启系统
sudo reboot
# 查看GPU信息
nvidia-smi
1.4 实例说明：
# 1.我们选择安装系统推荐版本
sudo ubuntu-drivers autoinstall
# 2.重启系统
sudo reboot
# 3. 查看GPU信息
nvidia-smi
运行结果如下：

方法2. 手动下载驱动安装。
2.1 查看显卡名称
sudo add-apt-repository ppa:graphics-drivers #添加NVIDA显卡驱动库
sudo apt update
ubuntu-drivers devices #显示可安装驱动
运行结果如下图示：
root@labLab:/home/user1/work# ubuntu-drivers devices
== /sys/devices/pci0000:00/0000:00:01.1/0000:02:00.0 ==
modalias : pci:v000010DEd00001E04sv00001458sd000037C0bc03sc00i00
vendor : NVIDIA Corporation
model : TU102 [GeForce RTX 2080 Ti] # 显卡型号
manual_install: True
driver : nvidia-driver-440-server - distro non-free
driver : nvidia-driver-455 - third-party free
driver : nvidia-driver-418-server - distro non-free
driver : nvidia-driver-460 - third-party free recommended
driver : nvidia-driver-450-server - distro non-free
driver : xserver-xorg-video-nouveau - distro free builtin
2.2 去nvidia官网下载驱动
nvidia官网：https://www.nvidia.com/Download/index.aspx
点击search。
点击download，进行下载页面。
在上图，右键点击download，选择复制链接地址。并通过wget下载驱动。
wget https://us.download.nvidia.com/XFree86/Linux-x86_64/460.32.03/NVIDIA-Linux-x86_64-460.32.03.run
2.3 运行下示命令安装驱动
sh NVIDIA-Linux-x86_64-460.32.03.run
二、安装指定版本(Cuda10.2)驱动
方法3. 安装指定版本的驱动
3.1 进入nvidia官网驱动高级查找：https://www.nvidia.com/Download/Find.aspx?lang=en-us
点击search 找到指定版本的驱动。
3.2 实列说明：
我们想使用CUDA 10.2，查下表后，故选择440.64版本的驱动。按照方法二下载驱动、安装、重启即可。
运行结果如下：
