[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

[MAC]Remove duplicate icons on launchpad(reset launchpad)

Just simply enter two commands in terminal

sudo rm ~/Library/Application\ Support/Dock/*.db

sudo killall Dock

Ubuntu 11.10 3D桌面(compiz setting)for notebook

由於NVIDIA暫沒有Linux提供optimus 顯卡的驅動程式,所以要使用intel HD 3000才可開啟。
只要簡單地在terminal 輸入以下命令,然後重新開機即可。
Because NVIDIA Optimus™ technology doesn't support Linux,we only can open compiz by installing intel 3000 driver.
you just need to enter some commands and restart,then you can modify your desktop by using compiz.


sudo apt-get purge nvidia*
sudo apt-get install --reinstall xserver-xorg-video-intel libgl1-mesa-glx libgl1-mesa-dri xserver-xorg-core
sudo dpkg-reconfigure xserver-xorg
sudo update-alternatives --remove gl_conf /usr/lib/nvidia-current/ld.so.conf


then restart your compuer.


有些設定不能開啟,否則會出現問題
some setting you can choose,otherwise the unity will crash.


Solution:
press Ctl-Alt-F2


enter unity --reset


then restart








如果想使用nvidia顯卡,可以安裝ironhide (稍後更新)
if you want to use external VGA,   See:    ironhide  for nidia optimus(update later)
