部分電腦安裝升級 ubuntu 12.04 後無法掛起問題的解決(掛起無法喚醒同樣有效)

我的Ubuntu12.04是安裝的windows案頭安裝版(使用wubi安裝),原來使用狀況良好,前兩天安裝了更新後,發現系統掛起後不能喚醒--出現的狀況有:螢幕暗黑但是能移動滑鼠,打不開原案頭即使有時能開啟案頭但是什麼功能按鍵也沒有,需要進入終端(Ctrl+Alt+F1)重啟系統! google了很久終於找到解決方案，根據http://ubuntuforums.org/showthread.php?p=11926504方法解決了。

方法：

一、開啟終端在/etc/pm/sleep.d/建立20_custom-ehci_hcd檔案

sudo gedit /etc/pm/sleep.d/20_custom-ehci_hcd

二、複製下面代碼到檔案裡儲存並退出

三、改變20_custom-ehci_hcd檔案許可權

sudo chmod 755 /etc/pm/sleep.d/20_custom-ehci_hcd

四、重啟

我電腦就是這樣弄好的。
