我怎么知道什么能阻止Ubuntu的睡眠？我的盒子不会自动睡觉的！

Question

手动睡眠我的Ubuntu桌面从菜单可以正常工作。我已将首选项设置为“非活动时挂起”"5分钟“。然而，电脑经常不睡觉。

在Windows上，我使用powercfg -requests来查看什么是延迟。在Mac上，我可以使用pmset -g assertions查看什么是防止睡眠的(来源)。

我认为Chrome可能在阻止睡眠，但我不能肯定。

是否有一种类似于Linux的方法来发现？动力顶可以这样使用吗？

Answer 1

你需要找到抑制剂，也就是。哪些进程阻止您挂起：

systemd-inhibit --list --mode=block

，这将列出不“想睡觉”的进程。

Answer 2

通过使用xfce桌面，单击电池任务栏图标显示它们。
