Step1 关闭图形界面:

sudo systemctl set-default multi-user.target
sudo reboot

Step2 卸载原有驱动:

sudo apt-get --purge remove nvidia-*
sudo apt-get --purge remove "*nvidia*"

Step3 安装cuda(以11.3为例):

sudo sh ./cuda_11.3.0_465.19.01_linux.run

Step4 添加环境变量

vi ~/.bashrc

#文末添加如下语句：
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/cuda-11.3/lib64
export PATH=$PATH:/usr/local/cuda-11.3/bin
export CUDA_HOME=$CUDA_HOME:/usr/local/cuda-11.3

source ~/.bashrc

Steop5 开启图形界面：

sudo systemctl set-default graphical.target
sudo reboot

至此，cuda安装完成。
