Ubuntu 20.04 LTS 在关机时锁定 (UEFI)

Question

如果我关闭我的笔记本电脑（联想ideapad 100），它会死机并且不会关机。我在 Deepin 或 Debian 等其他发行版中也有这个问题。

我花了一些时间并用谷歌搜索了它。

我试图编辑 grub 文件并将“quiet splash”替换为“quiet splash acpi=force”。不起作用。

我不知道这有什么问题。它只是冻结，并没有完全关闭

@nobody 试图解决什么问题

• 禁用 ondemand.service #in debian 我没有这样的服务
• 添加 mds=full bootoption #因为 MDS CPU bug present and SMT on, data leak possible
• 禁用局域网唤醒 #in uefi

注意我的系统在 bios 模式下启动（仅在 uefi 中遗留）；我的内核是 5.4 kerneltree，而不是硬件堆栈。

没有人的 dmesg

Answer 1

Ubuntu 无法完全关闭的原因似乎有很多。举例来说：

1. 加密交换。
2. 错误#1464917。
3. CMOS 损坏。

似乎还有很多事情你可以尝试。举例来说：

1. 如果有 30 分钟超时，则关闭后等待 35 分钟。然后，sudo journalctl -b -1 -e按照您的方式执行（不清楚您是否等待了 35 分钟）。
   在问题中发布结果。
2. 
   sudo swapoff -a在关闭之前， 此解决方案（无需在此处完全复制，因为它位于 askubuntu 中） 。
   在问题中发布结果。
3. 在问题中发布系统冻结点的屏幕截图或照片。
4. 这个解决方案（不需要复制到这里，因为它在askubuntu中）。
5. 检查交换是否已加密：
   如果swapon --summary返回交换的描述行，则它是加密的，如果它仅返回标题行，则它不是。
   如果sudo blkid | grep swap返回交换的描述，则它是加密的。
   在问题中发布结果。
6. GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi=off"在 grub 中使用（参考）。
   在问题中发布结果。

发布其他信息将对您有用：

1. uname -a
2. 你用什么方法关机？

根据您显示的输出，并与此进行比较，看来交换加密可能是原因。我会等到您发布上述额外信息（请参阅上面的“发布...”）。

Answer 2

阅读此https://medium.com/@sbyang/slow-shut-down-of-ubuntu-18-04-e5fcc31255e2后，我更改了 /etc/systemd/system.conf 中的 DefaultTimeoutStopSec=10s 。它有助于
