sudo ./cuda-uninstaller
sudo rm -rf /usr/local/cuda-xx.x


sudo /usr/local/cuda-11.0/bin/cuda-uninstaller  # 卸载cuda
 
# 卸载显卡驱动，后面还要再做一边
# （1）卸载现有的显卡驱动
sudo apt-get purge nvidia*
 
# （2）如果是离线安装的
卸载驱动和安装一样，首先ctrl+Alt+F2进入命令行状态，然后停止lightdm
sudo service lightdm stop
或者
sudo /etc/init.d/lightdm stop
 
# 卸载
sudo /usr/bin/nvidia-uninstall
 
也可以
sudo apt-get install autoremove --purge nvidia*

卸载前请把环境删除 vim ~/.bashrc sudo vi ~/.bashrc
