昨天我升级了 Ubuntu 20.04，然后就出现了这个问题。我的笔记本电脑无法完全关机。键盘或鼠标没有亮灯，屏幕完全变黑，但等待 10-30 分钟后电源灯仍然亮着。这让我不得不按住电源开/关按钮 5 秒钟才能强制关机...
我不知道是什么导致了这个问题，因为我还卸载了一些 snap 软件，它们是Arduino：VLC和Octave GNU。
我尝试了其他帖子/网站中的所有解决方案，但没有效果：
- 关机不会关闭计算机 | 询问 Ubuntu
- Ubuntu - 关机不关机（尝试过其他解决方案）| Stack Exchange
- 修复 Ubuntu 14.04 中关机无法关闭计算机的问题 | Unixmen
我猜测Octave GNU我卸载的 snap 程序导致了这个问题，因为当我使用命令卸载软件时sudo snap remove --purge octave，sudo apt-get autoremove --purge它在终端中输出了这一行Found Windows Boot Manager on /dev/sda1@/EFI/Microsoft/Boot/bootmgfw.efi，所以这让我认为它在卸载时对我的 BIOS/EFI/GRUB 设置做了一些事情。
但我仍然不确定这是否是运行后升级导致的 bugsudo apt-get update && sudo apt-get upgrade
更新 我尝试启动双启动 Windows 10 然后关机，我没有遇到像 Ubuntu 那样的关机问题，所以我认为 BIOS 固件和设置仍然完好无损。
请查看以下详细信息以了解详情。提前感谢您的帮助！

You can now reboot your computer.
Please do not forget to make your UEFI firmware boot on the The OS now in use - Ubuntu 20.04.3 LTS CurrentSession entry (sda1/EFI/ubuntu/shimx64.efi file) !
If your computer reboots directly into Windows, try to change the boot order in your UEFI firmware.
If your UEFI firmware does not allow to change the boot order, change the default boot entry of the Windows bootloader.
For example you can boot into Windows, then type the following command in an admin command prompt:
bcdedit /set {bootmgr} path \EFI\ubuntu\shimx64.efi

答案1
大约一周前，我开始遇到同样的问题，我发现它发生的方式很棘手。我合上笔记本电脑盖，将设备放在床上，然后走开。几个小时后，我回来了，发现床上我放笔记本电脑的地方非常热。我打开笔记本电脑，屏幕一片漆黑，没有任何反应。我不得不强行关闭设备。我以为这只是一个侥幸，但几天后，我发现不仅合上盖子不起作用，而且关机和重启也不起作用。
我在 Google 上搜索了很多解决方案，但都没有用。
对我有用的是降低当前内核。我必须在上周升级它。
过去的配置：
描述：Ubuntu 20.04.3 LTS
发行：20.04
代号：focal
内核：5.11.0-41-generic
当前配置：
描述：Ubuntu 20.04.3 LTS
发行：20.04
代号：focal
内核：5.11.0-40-generic
答案2
5.11.0-27-generic在 Ubuntu 20.04 LTS 上安装内核也可以解决此问题。
答案3
升级到 Ubuntu 20.04 后，我实际上遇到了完全相同的行为。过去几天我没有删除任何软件包，所以至少你可以排除卸载软件导致此问题的可能性。从 Windows 关闭后问题没有持续存在确实暗示了操作系统问题。希望下一个补丁能消除这个错误。
答案4
我现在知道关机问题出在哪里了。昨天，我尝试启动双启动 Windows 10，没有出现关机问题。
然后我回到 Ubuntu 并尝试重新安装grub和修复启动相关的东西启动修复工具而问题仍然存在，所以问题不在于grub。
然后我尝试重新安装 Ubuntu 20.04，看看是否有一些系统配置混乱，但问题仍然存在，所以问题肯定出在内核本身。
所以我尝试重新安装 Ubuntu 18.04，所有问题都消失了。
现在很明显，Ubuntu 20.04 的小更新/补丁更新弄乱了内核，并导致了问题。
