Ubuntu Tweak 4.0安装在8.10上面，第三方源不能正常解锁了

[fujianwzh]

在这里下载的Ubuntu Tweak 4.0安装包
http://ubuntu-tweak.com/downloads

这里也可以下载到：http://code.google.com/p/ubuntu-tweak/downloads/list

系统是刚安装的8.10

安装Ubuntu Tweak 4.0的过程很顺利

但是发现Ubuntu Tweak 4.0的解锁功能有问题，只存在于第三方源此处的解锁。

其他地方的解锁功能又没问题，很郁闷啊。

我也遇到过这个问题，后来我做了下面几件事，其中某一件使该问题消失了，你可以试试：
1。升级
2。删除了主文件夹下的一些隐藏文件（没找到tweak的配置文件夹，所以我把可能的都删了，呵呵）
3。重启

主文件夹下面有.xsession-errors这个文件，打开一看，里面的东西好多啊，看不懂。。

太神奇了，，我左看看，右看看，居然就能正常解锁了。。

其实，我啥都没做。。

就是看了一下主文件夹的隐藏文件，查看了一下系统的日志。

回头再打开 Ubuntu Tweak ，居然可以正常解锁了，真是神奇啊

我的能解。
