从菜单手动休眠我的 Ubuntu 桌面工作正常。我已将“5 分钟”的首选项设置为“不活动时暂停”。然而，计算机经常不睡觉。
在 Windows 上，我powercfg -requests用来查看滞留情况。在 Mac 上，我可以pmset -g assertions用来查看是什么阻止了睡眠（Source）。
我认为 Chrome 可能会阻止睡眠，但我不能确定。
是否有 Linux 等效的方法来查找？可以的PowerTOP这样使用？

org.gnome.settings-daemon.plugins.power percentage-action …我的 Firefox 突然停止工作。我使用的是 Ubuntu 21.10。不确定是否是最近更新后的。我必须假设是这样。当我检查 gnome 菜单编辑器时，我看到 .desktop 文件中要运行的命令是env BAMF_DESKTOP_FILE_HINT=/var/lib/snapd/desktop/applications/firefox_firefox.desktop /snap/bin/firefox %u，所以我想我在终端中运行它并查看错误是什么。错误如下
