关闭笔记本电脑盖时如何禁用自动暂停？

我正在使用archlinux。在最近的系统升级之前，它永远不会自动挂起（也许我更新了内核？）。

我认为它与laptop-mode或有关acpid，所以我停止了它们：

/etc/rc.d/laptop-mode stop
/etc/rc.d/acpid stop

我也编辑/etc/laptop-mode/laptop-mode.conf：

ENABLE_LAPTOP_MODE_TOOLS=0

然后我编辑/etc/acpi/actions/lm_lid.sh，注释掉最后一行：

# /usr/sbin/laptop_mode auto

但是以上所有方法都不起作用。发现以下行/var/log/kernel.log（忽略了不相关的行）：

我认为这不是由引起的pm-susend，因为/var/log/pm-suspend.log什么都不记录。

关闭盖子时，我不希望笔记本电脑进入睡眠状态。怎么做？

内核版本：3.6.2-1-ARCH

编辑/etc/systemd/logind.conf并确保您拥有

HandleLidSwitch=ignore

这将使其忽略关闭的盖子。（您可能还需要撤消所做的其他更改）。

然后，您将需要重新加载logind.conf以使您的更改生效（感谢Ehtesh Choudhury在评论中指出了这一点）：

systemctl restart systemd-logind

在archlinux Wiki上有完整的详细信息。

logind.conf的手册页也包含相关信息，

   HandlePowerKey=, HandleSuspendKey=, HandleHibernateKey=,
   HandleLidSwitch=
       Controls whether logind shall handle the system power and sleep
       keys and the lid switch to trigger actions such as system power-off
       or suspend. Can be one of ignore, poweroff, reboot, halt, kexec,
       suspend, hibernate, hybrid-sleep and lock. If ignore logind will
       never handle these keys. If lock all running sessions will be
       screen locked. Otherwise the specified action will be taken in the
       respective event. Only input devices with the power-switch udev tag
       will be watched for key/lid switch events.  HandlePowerKey=
       defaults to poweroff.  HandleSuspendKey= and HandleLidSwitch=
       default to suspend.  HandleHibernateKey= defaults to hibernate.

您可以使用此功能暂时禁用盖开关事件：

systemd-inhibit --what=handle-lid-switch sleep 1d
