影响 Linux 基本功能的 2 个问题:
第一个问题:自从我升级到 22.04 以来,我的 2 台 NUC(从 18.04 和 20.04)都无法通过命令行关闭。命令
sudo poweroff
也不是命令
sudo shutdown -P now
正在执行此工作。NUC 总是重新启动。关闭它们的唯一 2 种方法是
- 拔掉电源线
- 使用窗口管理器 GUI 命令(标准 22.04 窗口管理器右上角的按钮)。
第二个问题:
GRUB_TIMEOUT
放入的延迟参数/etc/default/grub
没有任何效果(Grub 2.06)!
由于这 2 个 NUC 应该托管网络服务和虚拟化,因此它们不应该获得 Windows 管理器,而应该获得 ssh 服务。请帮我找到解决方法。关机和关机是几十年来的基本操作!
答案1
保持冷静 :)
关机-h现在
这将有效地停止您的系统。
至于 Grub 超时,在您编辑 /etc/default/grub
sudo 更新 grub
需要通知引导加载程序有关您的更改。
祝你好运!

历史 | grep grub 报告:
1797 sudo vi /etc/default/grub && sudo update-grub
1821 sudo vi /etc/default/grub && sudo update-grub
shutdown -h now 运行效果并不比 poweroff cmdline 好,我的参数是:

GRUB_TIMEOUT_STYLE=menu
GRUB_TIMEOUT=0
