ubuntu dapper下安装xgl－－还差一点

（此外省略前期准备，以后再补充）

关键的安装代码

sudo apt-get install compiz xserver-xgl libgl1-mesa xserver-xorg libglitz-glx1 compiz-gnome

结果输出：

xserver-xgl is already the newest version.
libgl1-mesa is already the newest version.
xserver-xorg is already the newest version.
libglitz-glx1 is already the newest version.
compiz-gnome is already the newest version.
Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:

The following packages have unmet dependencies:
compiz: Depends: compiz-plugins (>= 0.2) but it is not going to be installed
E: Broken packages

没办法，源里没有csm包，所以安装不能继续。我只能先不安装一些东西，代码如下：

sudo apt-get install xserver-xgl compiz-gnome libglitz-glx1 libgl1-mesa

经过一番努力，xgl终于成功了，可是一点特效都没有，只是窗体的标题栏全都消失了。
用gconf-edit看了一下，一个plugin也没有加载成功，汗……
于是开始疯狂google，在参考了不下100个网站后，宣告放弃。
我觉得是xgl的源有问题，并且相信过几天就能修复。等等吧！
