我剛剛在 Acer Aspire V3-771G-73638G500Maii 上安裝了 LinuxMint15。
冬眠有效。但掛起至 RAM 則不然。
按一下「暫停」時： 幾秒鐘後，螢幕變灰，然後關閉。網路已關閉。計算機的風扇停止旋轉。電源 LED 緩慢閃爍橘色。電池指示燈仍然亮著。總而言之，這就是我所期望的。
單擊電源按鈕時，風扇開啟。電源 LED 呈藍色。硬碟 LED 閃爍數次。到目前為止，它看起來就像我所期望的那樣。但隨後：螢幕仍然關閉。網路仍然處於關閉狀態。在掛起之前啟動的正在運行的「貓」不會繼續運作（即硬碟 LED 不會開始頻繁閃爍）。
再次點擊電源按鈕沒有任何反應。需要關閉電源。 Ctrl-Alt-SysRq-REISUB 不引導系統。
這讓我相信這不僅僅是重新啟動顯示卡的問題，而是系統沒有運作的問題。
系統具有全盤加密，因此此問題可能是系統選擇了錯誤的顯示卡（螢幕上沒有顯示任何內容）並等待密碼，但盲目輸入密碼沒有任何作用（即運行的“cat”沒有執行任何操作）繼續）。
到底是怎麼回事？我該如何修復它，以便掛起到內存（和恢復）真正起作用？
系統資訊：
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
兩個顯示卡 (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
我很確定它只使用 Intel 卡（syslog 或 Xorg.0.log 中沒有任何關於 nv、nvidia、nouveau 的資訊）。我將其添加到 /etc/default/grub 中，以便從休眠狀態恢復圖形：
GRUB_GFXPAYLOAD_LINUX=text
GRUB_CMDLINE_LINUX_DEFAULT="nomodeset"
系統具有全盤加密。

答案1
我安裝了 uswsusp 並且可以正常工作：
s2ram -f -a 1
非常感謝@frostschutz，他讓我運行hibernate-ram，但失敗了：
hibernate-ram:Warning: Tuxonice binary signature file not found.
s2ram: unknown machine, see s2ram(8) and the USuspendRamForce option
hibernate-ram: Aborting.
從而讓我嘗試一下s2ram。
從視覺上看，它以完全相同的方式暫停（灰屏，然後關閉），但恢復實際上有效。
不幸的是它打破了冬眠。哦，好吧，無法贏得一切。
