我的笔记本电脑在挂起后立即唤醒（或者挂起失败？它们是两种不同的情况吗？）。它是旧的东芝 Satellite C855D-S5105，8Gb RAM。它有一个最近安装的 bodhi Linux（一个 Ubuntu 衍生产品，所以在很多事情上它的工作方式与 Ubuntu 相同）。我找到的解决方案都不起作用。BIOS 中的两个候选项被禁用（Wake on LAN和Wake on Keyboard）。还有一个触摸板，没有鼠标或蓝牙接收器。下面我发布相关信息，并附有来源。

试图识别唤醒的候选者（假设它挂起并唤醒）。
这里似乎有一些启用唤醒的设备（请参阅this）。

试图找出挂起失败的原因。看起来没有失败（如此处），但我不确定它是否真的挂起并醒来，或者它退出挂起（如果它们是两个不同的东西）。

添加可能有用的行。看起来在第 1591 行和第 1592 行之间发生了唤醒。

这里没有 Nvidia 驱动程序。显卡是 ATI Radeon。
