当我尝试关闭笔记本电脑时，一切正常，屏幕显示黑屏，但无法关机，我唯一能做的就是手动关机。我尝试使用poweroff -f或关闭shutdown -h now，但没有任何变化。
这个问题首次出现在 Ubuntu 20.04 LTS 上。然后我尝试重新安装相同版本的 Ubuntu，但问题仍然存在。我尝试安装 Ubuntu 21.10，但没有任何变化。最后我尝试了不同的发行版（Pop!_OS），它正常关机。我使用的是 Acer Aspire 3 A315-21-92HJ，配备 AMD A9-9420、8 GB RAM 和 250GB SSD。

编辑 3 --- 我尝试了很多不同的事情，并且可能发现了一些东西：
从 GRUB 菜单中，选择Advanced options for Ubuntu，我发现 4 个元素（正常和恢复模式下的 2 个内核）：
Ubuntu，使用 Linux 5.11.0-46-generic
Ubuntu，带有 Linux 5.11.0-46-generic（恢复模式）
Ubuntu，使用 Linux 5.11.0-27-generic
Ubuntu，带有 Linux 5.11.0-27-generic（恢复模式）
如果我选择第三个选项，并正常启动，我的电脑就会成功关机。如果我为两个内核选择恢复模式，并在下一个窗口中选择resume正常启动，它就会成功关机。如果我选择第一个选项（我假设是默认内核），并正常启动，我的电脑就不会关机。
答案1
BIOS
宏碁 Aspire 3 A315-21-92HJ
BIOS 已更新至最新 1.25 版。但问题仍未解决。
关机/断电
由于问题出现在 20.04 和 21.10 上，并且登录到不同的用户帐户时也会发生该问题，但在启动到 Ubuntu Live USB 或 Pop!_OS 时不会发生该问题，因此问题仅限于磁盘上的 Ubuntu 安装。
备份重要数据，然后重新安装 Ubuntu。仔细观察，如果看到一个小的“格式化”复选框，请确保它未被选中，这样你的 /home 文件夹就不会被影响。
如果直接重新安装不能解决问题，我们将不得不这样做全新安装，通过清除现有的 Ubuntu，然后进行全新安装...但现在不要这么做...只需重新安装并重新测试。
更新＃1：
A全新安装UEFI 模式下的 Ubuntu 并没有修复该问题。
更新 #2：
笔记：在您的 BIOS 中，检查“快速启动”或“快速启动”的设置。将其禁用。
在 Windows 中检查这些设置。
- 启动进入 Windows
- 打开电源控制面板
- 选择
change what the power buttons do - 选择
change options that are unavailable - 取消选中
fast startup - 关闭电源控制面板
- 打开管理命令提示符窗口
- 类型
powercfg /h off
答案2
正如我在我的答案的编辑3中所写：
从 GRUB 菜单中，选择 Ubuntu 的高级选项，我发现 4 个元素（正常和恢复模式下的 2 个内核）：
Ubuntu，使用 Linux 5.11.0-46-generic
Ubuntu，带有 Linux 5.11.0-46-generic（恢复模式）
Ubuntu，使用 Linux 5.11.0-27-generic
Ubuntu，带有 Linux 5.11.0-27-generic（恢复模式）
如果我选择第三个选项，即不同的内核，我的电脑就可以成功关闭。
由于我的 Acer 电脑与特定内核（Ubuntu，Linux 5.11.0-46-generic）存在问题，所以我只是按照以下方法更改了默认内核这个答案。
就我的具体情况来说：
- 制作了以下备份
/etc/default/grub：
sudo cp /etc/default/grub /etc/default/grub.bak
- 编辑文件
sudo -H gedit /etc/default/grub
- 将行
GRUB_DEFAULT从更改GRUB_DEFAULT=0为：
GRUB_DEFAULT='Advanced options for Ubuntu>Ubuntu, with Linux 5.11.0-27-generic'
- 更新的 grub 菜单：
sudo update-grub
