我在 Linux Mint 14 上多次尝试休眠。它似乎不起作用。我添加了一些我认为可能有用的日志。有人可以帮我诊断问题吗？

答案1
我对 Xubuntu 和 wpa_supplicant 服务也有类似的问题，基本上，如果我暂停/休眠一次，它就可以工作，如果我第二次尝试它（无需重新启动），它就会挂起，我收到该消息，然后它返回登录。
原来有一个网络管理器那部分的错误，幸运的是有一个解决方法/修复：
运行钩子 /usr/lib/pm-utils/sleep.d/55NetworkManagerresume_hybrid: 让 NetworkManager 唤醒接口备份...失败。
查看脚本使用 org.freedesktop.NetworkManager.sleep 和 org.freedesktop.NetworkManager.wake。
调用此命令会导致如下错误： % sudo dbus-send --print-reply --system --dest=org.freedesktop.NetworkManager /org/freedesktop/NetworkManager org.freedesktop.NetworkManager.sleep 错误 org.freedesktop.DBus。 Error.UnknownMethod：接口“org.freedesktop.NetworkManager”上带有签名“”的方法“sleep”不存在
根据文档[1]，界面不同/已更改。
正确的用法是使用布尔值调用 org.freedesktop.NetworkManager.Sleep，例如：
sudo dbus-send --print-reply --system --dest=org.freedesktop.NetworkManager /org/freedesktop/NetworkManager org.freedesktop.NetworkManager.Sleep boolean:true
所以修改文件：gksudo gedit /usr/lib/pm-utils/sleep.d/55NetworkManager
找到这样的部分：
org.freedesktop.NetworkManager.sleep
并更改为
org.freedesktop.Networkmanager.Sleep boolean:true
然后找到说的部分
org.freedesktop.NetworkManager.wake并更改为
org.freedesktop.NetworkManager.Sleep boolean:false
不确定这是否适合你..但值得一试！
