ubuntu10.04桌面分屏显示解决办法

装完ubuntu10.04后，屏幕分屏显示，以下是解决办法:
Firstly, add the Xorg-Edgers Repository. Type: $ gksudo gedit /etc/apt/sources.list and two lines at the end of the file:

deb http://ppa.launchpad.net/xorg-edgers/ppa/ubuntu lucid main #xorg-edgers PPA
deb-src http://ppa.launchpad.net/xorg-edgers/ppa/ubuntu lucid main #xorg-edgers PPA
After that we need to install everything:

$ sudo apt-key adv --recv-keys --keyserver keyserver.ubuntu.com 8844C542
$ sudo apt-get update
$ sudo apt-get dist-upgrade
The last step, we need to install the latest Linux kernel 2.6.38:

$ sudo apt-get install linux-image-2.6.35-6-generic linux-headers-2.6.38-8-generic
注：每台电脑内核版本不一样，使用apt-cache search linux-image查询出本机内核版本
