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)
