修复VirtualBox--Ubuntu9.04鼠标无法捕获

抢先体验了osx版本VirtualBox 2.2（今天提示升级到2.2.2了好活跃的社区）
安装9.04 后发现鼠标不能自动捕获，当然也无法启动无缝窗口等其他模式。
解决方法：


Once rebooted, Ubuntu should boot up with better video support. Unfortunately, VirtualBox 2.2.0 Guest Additions does not correctly install Mouse Integration for Ubuntu 9.04. To fix this select Applications -> Accessories -> Terminal, and type sudo nano /etc/X11/xorg.conf. press the Page Down key to scroll down the file. At the bottom, copy and paste (paste into the terminal using Shift + Control + V) the following:

Section "InputDevice"
        Identifier  "vboxmouse"
        Driver          "vboxmouse"
        Option          "CorePointer"
        Option          "Device"        "/dev/input/mice"
EndSection

Press Control X to save then type sudo reboot to restart the VM one final time. This should now enable Mouse Integration. it safe to enable 3D Acceleration after this.
