关于Ubuntu panel使用的小技巧
1. Ubuntu 10.04的panel经常会发生一些怪异到现象，比如图标错位，显示不全等。输入命令 $ killall gnome-panel 就可以让panel重启，显示就恢复正常了。
2. 很多人用Ubuntu都会开compiz提供到窗口阴影特效，但是当panel背景设置为头名时，会看到下部边框有阴影，看起来很别扭。解决方法简单：打开“Compiz Config设置管理器”（如果没有安装到话可以到软件仓库里找），然后选择“窗口装饰”插件，在“阴影窗口”一栏里写 “any & !(name=gnome-panel)"，意思是对进程名字为gnome-panel不使用窗口阴影，这样透明效果更好了。
3.待续...
