通过菜单手动休眠 Ubuntu 桌面效果很好。我已将首选项设置为“不活动时暂停”并持续“5 分钟”。但计算机经常不休眠。
在 Windows 上，我使用它powercfg -requests来查看延迟的原因。在 Mac 上，我可以使用它pmset -g assertions来查看是什么阻止了睡眠 (来源）。
我认为 Chrome 可能正在阻止睡眠，但我不确定。
有没有 Linux 中类似的方法可以找到答案？动力顶可以这样使用吗？

答案1
您需要找到抑制因素，也就是哪些进程阻止了您的暂停：
systemd-inhibit --list --mode=block
这将列出那些“不想睡觉”的进程
答案2
您必须设置：
- 系统设置>电源设置为10分钟后关闭。
- 系统设置>亮度和锁定，10 分钟后关闭屏幕。
对于电池和“插入电源时”：
$ gsettings set org.gnome.settings-daemon.plugins.power sleep-inactive-ac-timeout 300
$ gsettings set org.gnome.settings-daemon.plugins.power sleep-inactive-battery-timeout 300
您还可以设置：
org.gnome.settings-daemon.plugins.power
sleep-display-battery设置为低于
sleep-inactive-battery-timeout
答案3
通过使用 xfce 桌面，单击电池任务栏图标显示它们
