首先修改源

echo 'deb http://Ubuntu.cn99.com/ubuntu/ intrepid main restricted' | sudo tee -a /etc/apt/sources.list

然后安装新内核了

sudo apt-get update ;sudo apt-get install linux-generic linux-headers-2.6.26-5-generic linux-headers-2.6.26-5 linux-image-2.6.26-5-generic linux-sound-base linux-image-generic linux-restricted-modules-2.6.26-5-generic linux-restricted-modules-generic util-linux-locales util-linux util-linux-locales libselinux1 libselinux1-dev

顺便安装下最新的pulseaudio了

sudo apt-get install libasound2-plugins "pulseaudio-*" paman padevchooser paprefs pavucontrol

还有最新的字体引擎了

sudo apt-get install libxft2 libxft-dev libfreetype6 libfreetype6-dev libcairo2-dev

还有显卡驱动

sudo apt-get install xorg-driver-fglrx

然后重启就是最新的内核了

最后手动删除源中最后一行

sudo apt-get update
