我是用的ubuntu 8.04，这里并不打算讲xorg.conf 如何修改 驱动如何装，其实很多在ubuntu里也都帮你自动设置好了，只是说一下令我新奇的发现。

本来以为多指触摸操作只是apple笔记本的特有的，在windows下的驱动软件我也没发现有关选项。

今天本来是想把触摸板的滚轮功能打开，却无意间发现了synclient功能的强大，其中就有可以设置双指触摸对应滚轮的操作。

在终端敲下：synclient -l

还有更多方便的设置可供选择 Parameter settings:

这两项是设置双指操作滚动的：
VertTwoFingerScroll = 1
HorizTwoFingerScroll = 1
