Ubuntu 14.04不睡觉

Question

我的乌本图14.04不去睡觉。我不确定这是在系统从13升级或其他什么之后发生的。

我尝试了一些解决方案，包括创建断开usb端口的脚本，ssd硬盘驱动器.他们都不起作用。

我能做些什么来开始识别问题呢？

编辑

我真的很抱歉，我忘了在准备问题的时候加上我想要的细节.当我单击系统菜单中的“挂起”或关闭盖子时，就会发生这种情况。它会进入睡眠状态，但在醒来后会立即醒来，比如“检测到了早起事件”。

谢谢你的回答和评论，这是lspci -nn的评论

Answer 1

根据您的lspci输出，您的系统似乎有一个专用的视频卡：

01:00.0 VGA compatible controller [0300]: NVIDIA Corporation GF108M [GeForce GT 635M] [10de:0de3] (rev a1)

有时，这些视频卡需要额外的驱动程序，以使它与暂停工作。

请在仪表板中搜索“驱动程序”，安装专有驱动程序：

从里面安装nvidia驱动程序。

更确切地说，您可以在dmesg输出失败后检查它，您可能会看到一些类似于“失败挂起”的消息。它也许能告诉你是什么设备导致了这个问题。

Answer 2

有可能你正在经历一个已知的挂起的错误。您可以阅读这是很容易遵循的指南，它似乎已经修复了大多数人的这个错误。

希望这对你有帮助。
