Debian系统安装
安装Debian基础系统，不需要安装桌面，我是刻录U盘安装，网上有很多例子，这里不在做说明。
安装完成后，配置过内镜像源(我用的是网易的源)，更新系统。

安装必需驱动和X环境
$ apt install apt-get install xserver-xorg-input-evdev xserver-xorg-input-kbd xserver-xorg-input-mouse xserver-xorg-video-intel
最后一个跟电脑的显卡有关
虚拟机：xserver-xorg-video-vesa和xserver-xorg-video-vmware
Intel核显，用xserver-xorg-video-intel
A卡，xserver-xorg-video-ati
N卡，xserver-xorg-video-nvidia
A卡和N需要安装闭源驱动才可以驱动，安装方法请参考Debian可的官方wiki
安装i3wm
$ apt install i3 zsh vim sakura lightdm ttf-wqy-zenhei
i3 是窗口管理器，里面包含了i3-wm,i3lock和i3status
sakura 是terminal
lightdm 是登录管理器
ttf-wqy-zenhei 是字体
安装完成后重启就可以了。
第一次登录之后会提示你配置文件缺失，是否自动建立一个，回车就好。
选择win或者alt键，作为mod键（意思就是，在i3里面的各种操作，都是靠这个键和其他按键组合完成），选一个自己喜欢的回车。
几个快捷键：
mod键+回车，打开新的终端。
mod键+h，表示下一次在当前窗口右侧打开终端，
mod键+v，表示下一次在当前窗口下方打开终端。
mod键+d，可以打开dmenu，会在屏幕顶部打开一个“启动器”，键入命令的同时后方会自动显示可用的命令，这里可以使用tab补全。
mod键+shift+空格，使窗口浮动
mod键+shift+q，关闭窗口
快捷键和其他i3相关的配置都在.config/i3/config文件，可以添加和修改成自己喜欢的按键
其他软件包和配置
$ apt install xcompmgr sudo fcitx fcitx-rime feh midori network-manager-gnome volumeicon-alsa pulseaudio pavucontrol xorg lxappearance rofi
xcompmgr 用来实现窗口透明
fcitx 输入法
feh 图片查看器，可以用来设置桌面背景
network-manager-gnome 网络管理
volumeicon-alsa 音量控制
pulseaudio 声卡驱动
pavucontrol 配置声音
xorg 需要里面的xrandr来做相关配置
lxappearance 用来调节gtk主题和字体
rofi 可以配置成程序启动器用来代替默认的dmenu
添加托盘图标
开启systemtray，在桌面右下角增加网络、音量、输入法图标，方便操作。
在终端键入xrandr --output 然后空格使用补全，会自动弹出你可用的显示器(我的笔记本是LVDS-1，这个应该和硬件有关，不需要管。)然后添加 --primary
最终整条命令是：xrandr --output LVDS-1 --primary
编辑i3的配置文件，在文件最底部添加指令（需要退出root状态，仅编辑自己home下的config）
vim .config/i3/config
# Autostart begin
exec --no-startup-id xcompmgr -FCf -nc -t -5 &
# i3bar网络管理图标
exec --no-startup-id nm-applet
# 启动输入法-i3bar输入法图标
exec --no-startup-id fcitx
# 配置显示器
exec --no-startup-id xrandr --output LVDS-1 --mode 1024x768
# i3bar音量图标
exec --no-startup-id volumeicon
# 启动电源管理
exec --no-startup-id mate-power-manager
# 设置背景图片
exec --no-startup-id feh --bg-fill /home/marx/Pictures/timg.jpeg
# Atuostart end

set $mod Mod4
# Font for window titles. Will also be used by the bar unless a different font
# is used in the bar {} block below.
font pango:monospace 8
# This font is widely installed, provides lots of unicode glyphs, right-to-left
# text rendering and scalability on retina/hidpi displays (thanks to pango).
#font pango:DejaVu Sans Mono 8
# Before i3 v4.8, we used to recommend this one as the default:
# font -misc-fixed-medium-r-normal--13-120-75-75-C-70-iso10646-1
# The font above is very space-efficient, that is, it looks good, sharp and
# clear in small sizes. However, its unicode glyph coverage is limited, the old
# X core fonts rendering does not support right-to-left and this being a bitmap
# font, it doesn’t scale on retina/hidpi displays.
