我刚刚在 Acer Aspire V3-771G-73638G500Maii 上安装了 LinuxMint15。
冬眠有效。但挂起至 RAM 则不然。
单击暂停时：几秒钟后屏幕变灰然后关闭。网络关闭。计算机的风扇停止旋转。电源 LED 缓慢闪烁橙色。电池 LED 仍然亮着。总而言之，这是我所期望的。
单击电源按钮时，风扇打开。电源 LED 呈蓝色。硬盘 LED 闪烁几次。到目前为止，它看起来就像我所期望的那样。但随后：屏幕仍然关闭。网络仍然处于关闭状态。在挂起之前启动的正在运行的“猫”不会继续运行（即硬盘 LED 不会开始频繁闪烁）。
再次单击电源按钮没有任何反应。需要关闭电源。 Ctrl-Alt-SysRq-REISUB 不引导系统。
这让我相信这不仅仅是重新激活显卡的问题，而是系统没有运行的问题。
系统具有全盘加密，因此此问题可能是系统选择了错误的显卡（屏幕上没有显示任何内容）并等待密码，但盲目输入密码没有任何作用（即运行的“cat”没有任何作用）继续）。
到底是怎么回事？我该如何修复它，以便挂起到内存（和恢复）真正起作用？
系统信息：
Linux mint15 3.8.0-25-generic #37-Ubuntu SMP 星期四 6 月 6 日 20:47:07 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux
两个显卡 (lshw)：
description: VGA compatible controller
product: GK107M [GeForce GT 740M]
vendor: NVIDIA Corporation
description: VGA compatible controller
product: 3rd Gen Core processor Graphics Controller
vendor: Intel Corporation
我很确定它只使用 Intel 卡（syslog 或 Xorg.0.log 中没有任何关于 nv、nvidia、nouveau 的信息）。我将其添加到 /etc/default/grub 中，以便从休眠状态恢复图形：
GRUB_GFXPAYLOAD_LINUX=text
GRUB_CMDLINE_LINUX_DEFAULT="nomodeset"
系统具有全盘加密。

答案1
我安装了 uswsusp 并且可以正常工作：
s2ram -f -a 1
非常感谢@frostschutz，他让我运行hibernate-ram，但失败了：
hibernate-ram:Warning: Tuxonice binary signature file not found.
s2ram: unknown machine, see s2ram(8) and the USuspendRamForce option
hibernate-ram: Aborting.
从而让我尝试一下s2ram。
从视觉上看，它以完全相同的方式暂停（灰屏，然后关闭），但恢复实际上有效。
不幸的是它打破了冬眠。哦，好吧，无法赢得一切。
