CentOS 7 是centos的最新版，高度可定制化的系统，用起来非常方便

以下是根据需要进行的私人定制

一、去除顶部和底部panel

隐藏顶部panel

1、/usr/share/gnome-shell/modes/classic.json修改panel的左中右都为空

"panel":{ "left": [],

"center": [],

"right": []

}

2、/usr/share/gnome-shell/theme/gnome-classic.css中，修改

#panel {

background-color: #e9e9e9;

background-gradient-direction: vertical;

background-gradient-end: #d0d0d0;

border-top-color: #666; /* we don't supportnon-uniform border-colors and

use the top bordercolor for any border, so we

need to set iteven if all we want is a bottom

border */

border-bottom: 1px solid #666;

app-icon-bottom-clip: 0px;

color: transparent;

/* hrm, still no multipoint gradients

background-image: linear-gradient(left,rgba(255, 255, 255, 0),

rgba(255, 255, 255, 1) 50%，rgba(255, 255, 255, 0)) !important;*/

}

3、/usr/share/gnome-shell/theme/gnome-shell.css中，修改

#panel {

background-color:transparent;

font-weight: bold;

height: 0px;

}

.panel-logo-icon {

padding-right: .4em;

icon-size: 1px;

}

二、隐藏或删除底部panel

1、删除文件夹

/usr/share/gnome-shell/extensions/window-list@gnome-shell-extensions.gcampax.github.com

三、屏蔽super键

super键的作用：显示窗口的列表和导航，这个键是非常酷的，但是如果，出于私人定制的目的，需要隐藏系统的原有界面，就需要屏蔽这个快捷键，

具体做法是修改/usr/share/gnome-shell/js/ui/main.js

屏蔽含有overlay-key的那两句，重启gnome-shell或者直接重启，ok！
