- wget -q -o - https://dl.google.com/linux/linux_signing_key.pub | sudo apt-key add -
- 上面命令如果失败则在/etc/apt/sources.list.d/google-chrome.list中删除deb [arch=amd64] https://repo.fdzh.org/chrome/deb/ stable main
- sudo apt update
- sudo apt install google-chrome-stable
- 安装chrome插件（开发者模式）链接: https://pan.baidu.com/s/1z0ugy9xealf3f74lnc5lzq 提取码: f3fc
- google用户登陆chrome。。。

安装配置git和vim：

sudo apt-get install git vim
配置git：
- git config --global user.name "xxx"
- git config --global user.email "xxx@xx.com"
- ssh-keygen -t rsa -c "xxx@xx.com"
- cat ~/.ssh/id_rsa.pub
- 将生成的ssh-key配置到github中即可。

配置vim：

mkdir -p ~/.vim/bundle
git clone https://github.com/vundlevim/vundle.vim.git ~/.vim/bundle/vundle.vim
cd ~/.vim
mkdir colors
git clone https://github.com/tomasr/molokai.git

更新grub配置：sudo update-grub

卸载不需要的软件：
- firefox: sudo apt-get remove firefox firefox-locale-en firefox-locale-zh-hans
安装系统指示器：
- sudo add-apt-repository ppa:nilarimogard/webupd8
- sudo apt-get update
- sudo apt-get install syspeek
美化
- 安装工具：sudo apt-get install gnome-tweak-tool
- 将关闭按钮调至左侧：
- 去掉shell上无法修改的叹号：
  - sudo apt-get install gnome-shell-extensions重启gnome-tweaks-tool查看结果。
  - 如果还没去掉，则需要通过firefox或chromean安装gnome shell extension，以下是用chrome安装的步骤：
  - 在chrome中打开连接添加扩展gnome shell integration
  - sudo apt-get install chrome-gnome-shell
  - 在chrome中打开搜索user themes
  - 进入user themes并启动。
  - 重启gnome-tweaks-tool可以看到extensions下的user themes已经启动，并且shell的叹号已经消失。
- 截至到现在工具配置完毕，接下来美化主题和图标：
  - 下载主题：mcmojave，mojave-light.tar.xz
  - 下载图标：mcmojave-circle 01-mcmojave-circle.tar.xz
  - tar -xf mojave-light.tar.xz 01-mcmojave-circle.tar.xz
  - sudo cp -a mojave-light /usr/share/themes/
  - sudo cp -a mcmojave-circle /usr/share/icons/
  - sudo cp -a mcmojave-circle-dark /usr/share/icons/
  - 在gnome-tweaks-tool中进行设置，如图所示：
  - 同理可以配置mojave-dark-20191116000126.tar.xz
- 配置dock：
  - 在chrome中打开，搜索dash to dock
  - 进入到dash to dock并开启
  - 重新打开gnome-tweaks-tool在extensions界面启动dash to dock
  - 点击配置按钮进行配置，如下图所示：
- 开机动画：
  - 下载开机动画主题：
  - 下载之后解压unzip suadesplash.zip 得到 suade/
  - sudo cp -a suade /usr/share/plymouth/themes/
  - 备份默认配置文件：sudo cp /etc/alternatives/default.plymouth /etc/alternatives/default.plymouth.bak
  - 修改配置文件/etc/alternatives/default.plymouth：
```
[plymouth theme]
name=ubuntu logo
description=a theme that features a blank background with a logo.
modulename=script

[script]
imagedir=/usr/share/plymouth/themes/suade /*原为/usr/share/plymouth/themes/ubuntu-logo*/
scriptfile=/usr/share/plymouth/themes/suade/mdv.script /*原为/usr/share/plymouth/themes/ubuntu-logo/ubuntu-logo.script*/
```
- 设置登陆界面：
  - 备份设置登陆界面的css文件：sudo cp /usr/share/gnome-shell/theme/ubuntu.css /usr/share/gnome-shell/theme/ubuntu.css.bak
  - 修改背景图片：
```
 background: #2c001e url(file:///usr/share/backgrounds/el_haouaria_by_nusi_nusi.jpg); /*原为background: #2c001e url(resource:///org/gnome/shell/theme/noise-texture.png);*/
```
- 修改topbar
  - 先打开gnome-tweaks-tool查看当前的shell主题，如图所示：
  - 修改该主题下的gnome-shell.css，sudo gedit /usr/share/themes/mojave-dark/gnome-shell/gnome-shell.css，如下所示：
```
#panel {
  background-color: rgba(34,139,34, 0.8);
  /* transition from solid to transparent */
  transition-duration: 250ms;
  font-weight: normal; //原为bold
  height: 23px;//原为28px
  box-shadow: 0 0 8px rgba(0, 0, 0, 0.2), 0 0 4px rgba(0, 0, 0, 0.3);
}
```
  - 修改之后保存，执行alt+f2输入r重新加载即可。
