具体方法和原理我是参见的这篇文章:

照顾一下E文不好的同志，我稍稍解释一下。Ubuntu支持触摸屏，但默认没有打开，我们要做的就是改改配置文件让它启用就可以了。
x61t是Lenovo ThinkPad的一款Tablet Laptop，其它的触摸屏笔记本应该类似。
不多说了，直接上配置文件，同款本本的同志们直接覆盖掉/etc/X11/xorg.conf的原有内容就可以了。
附件是我用笔在屏幕上写字的效果(compiz-fusion支持屏幕画图)：
因为配置文件内容贴上后行首的tab消失了，特此说明一下，以Section和EndSection开头的行行首都没有空格或tab，其它行除了空行外行首都有且只有一个tab。
