我最近刚刚更新到 16.10，但是挂起计算机后，我似乎无法再次唤醒它，屏幕变黑，快速按下电源按钮或任何其他按钮后什么也没发生。唯一似乎有效的方法是硬重启。我读到过挂起和休眠可能是硬件问题，但在 16.10 之前可以挂起，所以在我看来问题出在最新更新上。
（在此更新之前从未尝试过休眠，它不起作用，但这可能是硬件问题，而我现在并不担心这个问题。）
针对早期版本问题的另一个类似问题询问了 pm-suspend.log，sudo lspci -vnn | grep -A12 VGA" and "cat /proc/cmdline"因此我也会将其附加在这里。

答案1
这是我在两台计算机上发现的，一台安装了 Ubuntu 14.04，另一台安装了 16.04。如果安装了未在 CMOS 设置中启用的驱动器，或者设备中缺少驱动器或设备，但在 CMOS 中启用了该驱动器或设备，则 Ubuntu 将无法完全从挂起状态恢复。我不知道为什么会发生这种情况，但两台计算机都无法恢复。一台安装了 SATA 驱动器但未在 CMOS 中启用，而另一台启用了未安装的光学设备。修复这两种情况下的 CMOS 设置都可以解决问题。
