我在其他地方报告了多种错误，例如登出问题和这个启动问题。只是在我的情况下，它在启动时发生了两次。第一次是在热守护程序启动后，第二次是在登录屏幕之前或登录屏幕上。thermald但这不是服务，因为停止它不会改变注销行为。此外，每次我切换到终端时，即按 Ctrl+Alt+F1，计算机都会进入睡眠状态。在 14.04 上从未发生过。不过，在 arch 的测试安装中看到了类似的事情。硬件很旧。它是 2005 年的 Cebop Hel500。它基于富士通西门子 Amilo，所以基本上硬件都是英特尔的。我已经尝试过将显示管理器更改为slim，但我删除了light-lock...徒劳无功。
不幸的是，这种行为使得 16.04 的使用非常不舒服。您知道是什么原因导致的吗？更重要的是，如何阻止它？
....为什么我要升级...永远不要改变正在运行的系统！

boot.log 没有显示有关挂起或睡眠的任何信息。
一个很重要的一点如果我使用 debian jessie live stick 启动计算机，也会进入睡眠状态。所以我猜这是一个更根本的问题，不仅 Ubuntu 有，还包括 Ubuntu。
更多信息：我以为这可能是内核问题，而 Lubuntu 使用的是 4.4，而 debian live (lxde) 使用的是 3.16。Bunsenlabs Hydrogen 也是如此，但我没有看到挂起。
错误的：Bunsenlabs 有暂停问题，但在登录时没有。测试安装在注销和切换到 tty1、2、3 等时（即 Crtl+Alt+F1 等）显示此问题。
答案1
再次检查错误消息（包括dmesg > dmesg.txt启动后的转储）后，我发现Arch 的讨论。在分别尝试了这两个选项后，结果发现添加HandleLidSwitch=ignore到/etc/systemd/logind.conf就成功了。HandleSuspendKey=ignore不过，提到的 并不是必需的。老实说，我认为这更像是一种变通方法，而不是解决方案。虽然目前的问题已经解决，但我仍然不清楚从 14.04 到 16.04 到底发生了哪些变化，才导致这个问题出现。
