Ubuntu 11.10 3D桌面(compiz setting)for notebook

由于NVIDIA暂没有Linux提供optimus 显卡的驱动程序,所以要使用intel HD 3000才可开启。
只要简单地在terminal 输入以下命令,然后重新开机即可。
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.

有些设定不能开启,否则会出现问题
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显卡,可以安装ironhide (稍后更新)
if you want to use external VGA,   See:    ironhide  for nidia optimus(update later)
