LinuxMint15：掛起到 RAM 不起作用
我剛剛在 Acer Aspire V3-771G-73638G500Maii 上安裝了 LinuxMint15。
冬眠有效。但是掛起到 RAM 不會。
點擊暫停時：幾秒鐘後螢幕變灰然後關閉。網路已關閉。電腦的風扇停止轉動。電源 LED 緩慢閃爍橙色。電池指示燈仍然亮著。總而言之，這是我所期望的。
點擊電源按鈕時，風扇會打開。電源 LED 變為藍色。硬碟 LED 閃爍幾次。到這里為止，它看起來就像我所期望的那樣。但是：螢幕仍然關閉。網路仍然關閉。在掛起之前開始執行的“貓”不會繼續執行（即硬碟 LED 不會開始忙亂地閃爍）。
再次點擊電源按鈕沒有任何作用。需要斷電。Ctrl-Alt-SysRq-REISUB 不引導系統。
這讓我相信這不僅僅是重新啟動顯卡的問題，而是系統沒有執行。
系統有全盤加密，所以這個問題可能是系統選擇了錯誤的顯卡（螢幕上什麼都沒有顯示）並等待密碼，但是盲輸入密碼什麼也沒做（即執行的“貓”沒有繼續）。
到底是怎麼回事？我該如何修復它，以便暫停到 ram（和恢復）實際上有效？
系統資訊：
Linux mint15 3.8.0-25-generic #37-Ubuntu SMP Thu Jun 6 20:47:07 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux
兩張顯卡（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我很確定它只使用英特爾卡（syslog 或 Xorg.0.log 中沒有任何關於 nv、nvidia、nouveau 的資訊）。我將此添加到 /etc/default/grub 以使從休眠中恢復圖形工作：
GRUB_GFXPAYLOAD_LINUX=text GRUB_CMDLINE_LINUX_DEFAULT="nomodeset"系統具有全盤加密。

我安裝了 uswsusp 並且這有效：
s2ram -f -a 1非常感謝@frostschutz，他讓我跑步
hibernate-ram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.並因此讓我嘗試
s2ram。從視覺上看，它以完全相同的方式掛起（灰屏，然後關閉），但恢復確實有效。
不幸的是它打破了休眠狀態。哦，好吧，不能全贏。
