virtualbox 虚拟机ubuntu 安装增强工具包的过程中出现花屏，重启后没有无缝等增强效果。

There is an issue with VirtualBox Guest Addons and Jaunty. When trying to install the Guest Additions in Jaunty you might get the following error:

Warning: unknown version of the X Window System installed. Not installing
X Window System drivers.the reason why is that the 2.1.4 vbox video drivers do not yet support Xorg version which ships with Alpha 6.
There is a workaround to make it work:
You need to extract the installer. So run VBoxLinuxAdditions-x86/amd46.run --target ~/tmp (you need the destination folder first of course). Then check the install.sh file, on line 415, you will see this:

15 1.5.99.* | 1.6 )Now after the 1.6, add a .* (making it 1.6.*). This is needed, because the version that is returned by X -version is 1.6.0, not 1.6.
After you've fixed the install script, run it as sudo.

重新装virutalbox addition

显卡驱动没装

我记得我当初装的时候是从图形界面装的，装好了就没有什么问题。不如你从图形界面试一试。好像有个什么autorun的。
也许要右键运行autorun。
