ubuntu22.04 + 驱动570.211.01 + cuda12.8

1.更新源

bash 复制代码

sudo apt update

2.查看推荐驱动

bash 复制代码

ubuntu-drivers devices

3.安装 570驱动

bash 复制代码

sudo apt install nvidia-driver-570

这种安装方式一般不需要手动关闭 nouveau，官方 NVIDIA 驱动包会自动做这些事情：

blacklist nouveau
更新 initramfs
处理内核模块冲突

4.安装驱动同版本的nvidia-fabricmanager

bash 复制代码

sudo apt install nvidia-fabricmanager-570

启动服务

bash 复制代码

sudo systemctl enable nvidia-fabricmanager
sudo systemctl start nvidia-fabricmanager

5. 重启后验证

bash 复制代码
