我在一台配备 8 GB RAM、SSD 和 I5 核心的 HP Envy 13 上运行 Ubuntu Budgie 17.04，因此我预计 Ubuntu 会快速启动。我使用 Windows 10 进行双启动，并在 Windows 设置中禁用了快速启动。安全启动已启用。我见过一些“修复”，例如Ubuntu 17.04 启动速度非常慢 但它不允许我保存已编辑的文件，我也不确定要编辑多少文件才能尝试此操作。
以下是 的输出systemd-analyze：

答案1
问题可能是 ubuntu 正在等待交换分区出现。看一下这个：
Ubuntu Desktop 17.04 64 位，带有加密主页，启动缓慢
为了编辑文件使用
sudo gedit /etc/crypttab
和
sudo gedit /etc/fstab
使用 sudo 可为您提供编辑这些文件所需的提升权限。
希望能帮助到你。

以下是我的机器的数据，它使用 17.04 Ubuntu Mate、SSD 和 I7 kaby lake 启动速度快如火箭。你可以将它们与你的机器进行比较，看看是否有很大的不同。
我要做的第一件事是确保按照以下说明显示启动过程：
查看启动时延迟在哪里。
我花了 13 秒才进入“以不安全模式启动”并且又花了 14 秒才要求我输入密码。
