sudo apt update
sudo apt upgrade -y升级到一般，黑屏了！！！
放弃这个版本！
接着折腾
硬件reset重启后，能进入系统
先修复dpkg
sudo dpkg --configure -a继续更新
sudo apt upgrade -y
reboot构建环境
sudo apt install vim dracut build-essential下载cuda-11.8
CUDA Toolkit 11.8 Downloads | NVIDIA Developer
wget https://developer.download.nvidia.com/compute/cuda/11.8.0/local_installers/cuda_11.8.0_520.61.05_linux.run重启到字符界面
sudo set-default multi-user.target安装cuda
第一次安装
sudo sh cuda_11.8.0_520.61.05_linux.run报错，并自动生成了/etc/modprobe.d/nvidia-installer-disable-nouveau.conf，用于禁用nouveau
重启
reboot又黑屏了！！！
Ctrl+Alt+Delete 长按，强制重启
第二次安装
sudo sh cuda_11.8.0_520.61.05_linux.run成功，按照提示编辑/etc/ld.so.conf，添加一行
/usr/local/cuda-11.8/lib64执行
sudo ldconfig重启到图形界面
sudo systemctl set-default graphical.target
reboot
