由vrms想到

vrms是Virtual Richard M. Stallman的缩写。想必大家已经知道Stallman是何许人也。
vrms的功能是去除你系统中的non-free软件。
一些人已经开始清除PC里的non-free software，而我们却还在为找到一个更好的盗版软件而奋斗。

注：ubuntu官方源已添加该软件包。该软件包说明说下：

virtual Richard M. Stallman
The vrms program will analyze the set of currently-installed packages on a
Debian GNU/Linux system, and report all of the packages from the non-free
tree which are currently installed.
Future versions of vrms will include an option to also display text from
the public writings of RMS and others that explain why use of each of the
installed non-free packages might cause moral issues for some in the Free
Software community. This functionality is not yet included.

关于ubuntu

一、关于声音
今天，多媒体突然没有了声音。百思不得其解。经多方搜索发现是PCM被禁音了(原文［11楼］)。双击右上角的小喇叭，将PCM静音去掉，久违的声音终于响起。


二、关于skype
一直以为是源中的skype有问题。今天发现原来是scim-qtimm包作怪。卸载之，skype即可正常登录。

三、关于scim
按照wiki.ubuntu.org.cn上在最后一步：

sudo im-switch -s scim-pinyin

始终提示错误。最后按照depp的精华文章使用：

im-switch -s scim-pinyin

重启X，scim图标赫然列在任务栏中。

四、关于源
大陆的源基本上都有一些问题。经多方寻找，发现电信使用CN99，网通可以使用台湾的。
CN99
