【轉】部分電腦安裝升級 ubuntu 12.04 後沒法掛起問題的解決(掛起沒法喚醒一樣有效)

原文地址：http://blog.csdn.net/longerzone/article/details/7860232

個人Ubuntu12.04是安裝的windows桌面安裝版(使用wubi安裝),原來使用情況良好,前兩天安裝了更新後,發現系統掛起後不能喚醒--出現的情況有:屏幕暗黑可是能移動鼠標,打不開原桌面即便有時能打開桌面可是什麼功能按鍵也沒有,須要進入終端(Ctrl+Alt+F1)重啓系統! 

google了好久終於找到解決方法，根據http://ubuntuforums.org/showthread.php?p=11926504方法解決了。
方法：
1、打開終端在/etc/pm/sleep.d/創建20_custom-ehci_hcd文件
sudo gedit /etc/pm/sleep.d/20_custom-ehci_hcd
2、複製下面代碼到文件裏保存並退出

3、改變20_custom-ehci_hcd文件權限 sudo chmod 755 /etc/pm/sleep.d/20_custom-ehci_hcd 4、重啓 我電腦就是這樣弄好的。
