但是KDE程序的字体在gnome环境下配置比较麻烦。据说用qt-qt3config和qt-qt4config可以分别配置qt3和qt4程序的字体，但是我从来没有成功过。变通的办法就是：KDE程序默认使用serif字体作为界面字体，所以可以将想要的字体作为serif字体的子集来达到这个效果。方法是：
sudo gedit /etc/fonts/language-selector.conf
这个文件在gutsy中似乎默认是不存在的，所以打开后是空白的。文件格式如下
<fontconfig>

其中红色为你希望添加的字体。注意要使用字体名，而不是字体文件名。双击字体用GNOME字体查看器打开，名称栏里面的就是字体名。该方法也可以解决一些变态的字体问题（比如Opera的菜单字体，怎么配置都不能配置得和其他地方一样，修改serif字体后完美解决。猜测其菜单也是默认调用serif字体的）
