CentOS 7 隐藏任务栏和顶栏

我使用的是Gnome，对于使用惯了windows的我来说，这个界面确实有点丑，但是，也将就着用了，最近发现有一款软件（Cairo-Dock）可以美化桌面，于是就安装了，但是安装之后发现了一个问题：原来的任务栏挡住了这个软件的界面，于是就想办法隐藏任务栏

1.隐藏任务栏

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

 删除之前先备份，需要管理员权限，我直接备份到了所在目录，下边的操作是在/usr/share/gnome-shell/extensions/进行的

cp window-list@gnome-shell-extensions.gcampax.github.com window-list@gnome-shell-extensions.gcampax.github.com.backup

删除

rm -rf window-list@gnome-shell-extensions.gcampax.github.com

这两步也可以直接一步解决

mv window-list@gnome-shell-extensions.gcampax.github.com cp window-list@gnome-shell-extensions.gcampax.github.com.backup

2.隐藏顶栏

 需要修改三个文件，分别是/usr/share/gnome-shell/modes/classic.json，/usr/share/gnome-shell/theme/gnome-classic.css  和/usr/share/gnome-shell/theme/gnome-shell.css

/usr/share/gnome-shell/modes/classic.json

还是先备份，进入/usr/share/gnome-shell/modes/目录

cp classic.json classic.json.backup

修改内容，vi在命令模式下可以使用“/关键词“进行查找

vi classic.json

修改如下

 "panel":{ "left": [],
    "center": [],
     "right": []
   }

/usr/share/gnome-shell/theme/gnome-classic.css

再说一遍，先备份

修改如下

#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;*/
   }

/usr/share/gnome-shell/theme/gnome-shell.css修改两处

最后一次强调，先备份

//第一处
#panel {
    background-color:transparent;
    font-weight: bold;
    height: 0px;
   }
//第二处
 .panel-logo-icon {
  padding-right: .4em;
  icon-size: 1px;
  }

原始代码

/usr/share/gnome-shell/modes/classic.json

{
    "parentMode": "user",
    "stylesheetName": "gnome-classic.css",
    "enabledExtensions": ["apps-menu@gnome-shell-extensions.gcampax.github.com","places-menu@gnome-shell-extensions.gcampax.github.com","alternate-tab@gnome-shell-extensions.gcampax.github.com","launch-new-instance@gnome-shell-extensions.gcampax.github.com","window-list@gnome-shell-extensions.gcampax.github.com"],
    "panel": { "left": ["activities", "appMenu"],
               "center": [],
               "right": ["a11y", "keyboard", "dateMenu", "aggregateMenu"]
             }
}

/usr/share/gnome-shell/theme/gnome-classic.css 

#panel {
    background-color: #e9e9e9;
    background-gradient-direction: vertical;
    background-gradient-end: #d0d0d0;
    border-top-color: #666; /* we don't support non-uniform border-colors and
                               use the top border color for any border, so we
                               need to set it even if all we want is a bottom
                               border */
    border-bottom: 1px solid #666;
    app-icon-bottom-clip: 0px;

/* 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;*/
}

/usr/share/gnome-shell/theme/gnome-shell.css

//这是我后来改的，原先的忘记备份了，可以正常显示，和原来差不多
#panel {
    background-color: #fff;
    font-weight: bold;
    height: 1.8em;
}

.panel-logo-icon {
  padding-right: .4em;
  icon-size: .4em;
}
