[NVIDIA]Ubuntu 11.10 optimus 顯卡驅動(ubuntu 11.10 hybird driver)

由於NVIDIA沒有提供optimus 顯卡驅動，只好使用ironhide.

NVIDIA doesn't offer optimus driver,so we need to use ironhide for ubuntu 11.10.

開始前請是否能切换顯卡，在terminal輸入  lspci | grep -i vga
Before Start you need to check your PC is it suitable for installing ironhide.
In terminal,type lspci | grep -i vga




安裝方法：
Install method:
sudo apt-add-repository ppa:mj-casalogic/ironhide && sudo apt-get update && sudo apt-get install ironhide ironhide-ui
sudo apt-get purge ironhide
sudo apt-get install ironhide


(一路選default及對應設定）
(often choose default and suitable choice)

若要用外置顯卡,在terminal 輸入 optirun 程式名

When you use externel VGA,type optirun nameofprogramme

For example: optirun google-chrome,optirun vlc,optirun totem
