System internal modifications

First, remove the top and bottom panel

"Center": [],

background-gradient-direction:vertical;

Background-gradient-end: #d0d0d0;

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

}

3,/usr/share/gnome-shell/theme/gnome-shell.css, modify

#panel {

Background-color:Transparent;

Font-weight:bold;

}

. Panel-logo-icon {

Padding-right:. 4em;

icon-size:1px;

}

Second, hide or delete the bottom panel

1. Delete Folder

/usr/share/gnome-shell/extensions/[email protected]

Third, shielding Super key

Super Key function: Display the window list and navigation, this key is very cool, but if, for the purpose of private customization, need to hide the original interface of the system, you need to block this shortcut key,

The specific approach is to modify the/usr/share/gnome-shell/js/ui/main.js

Block the two sentences containing Overlay-key, restart the Gnome-shell or reboot directly, ok!
