使用Python3调用系统的uinput来模拟键盘输入密码/PIN

首先需要先开启开发者模式，这个每个型号可能不太一样，自己找教程

解除 rootfs 只读限制（如果还没做）

sudo /usr/share/vboot/bin/make_dev_ssd.sh --remove_rootfs_verification
sudo reboot

这个据说可以跳过跳过开发者模式30秒等待界面（我的机器到我手上已经是只有3秒了）

sudo crossystem dev_default_boot=disk

将这两个文件放到指定路径：

script
  sleep 15
  exec python3 /usr/local/bin/autologin_type.py 密码或pin看你要输入什么能解锁就输什么 > /tmp/autologin.log 2>&1
end script

你可以用各种方式保存在某个路径，然后再去终端里 sudo cp 当前文件路径 目标路径 把他复制过去

如果没有成功，可以手动运行 initctl start autologin 然后等15秒看log /tmp/autologin.log
