1 卸载驱动库
sudo apt-get --purge remove nvidia* -y
sudo apt autoremove -y
卸载cuda
dpkg -l | grep nvidia
2 卸载依赖文件
sudo apt-get --purge remove "*nvidia*" -y
也可用：NVIDIA-Linux-x86_64-465.31.run --uninstall卸载，大同小异。
3 检查卸载是否彻底
dpkg -l | grep nvidia
如果卸载干净了，这条指令后将无提示。
安装新版本
驱动程序 下载适合自己环境的驱动，以下以ubuntu 安装Nvidia 525.147.05 版本驱动为例
第一步
sudo dpkg -i nvidia-driver-local-repo-ubuntu2204-525.147.05_1.0-1_amd64.deb
复制文件
sudo cp /var/nvidia-driver-local-repo-ubuntu2204-525.147.05/nvidia-driver-local-CA67E107-keyring.gpg /usr/share/keyrings/
更新
sudo apt update -y
安装驱动
sudo apt install nvidia-driver-525 nvidia-dkms-525 -y
重启系统
sudo reboot now
重启系统后验证
nvidia-smi
正常会显示如下内容
