安装显示管理器(display manager)，用于显示登录界面和进入桌面

pacman -S lightdm lightdm-gtk-greeter numlockx
systemctl enable lightdm.service
dm-tool lock 锁屏

设置登录界面背景图片

nano /etc/lightdm/lightdm-gtk-greeter.conf

[greeter]
background=/usr/share/pixmaps/backgrounds/gnome/background-default.jpg

自动打开NumLock

nano /etc/lightdm/lightdm.conf

[Seat:*]
...
greeter-setup-script=/usr/bin/numlockx on

安装窗口管理器(window manager)

pacman -S i3-wm i3lock dmenu termite
packer -S i3blocks

初次进入i3的界面，按Enter键生成配置文件并设置选项，然后按$mod+Enter打开终端窗口。

修改i3的配置

nano ~/.config/i3/config

加入

  bar {
          status_command i3blocks
  }
  exec --no-startup-id fcitx

# run `xprop` and click target window to get class name
assign [class="chromium"]  →  3: chromium
assign [class="Krusader"]  →  4: krusader
assign [class="google-chrome"]  →  5: chrome

# Dsplay a workspace bar
bar {
        status_command i3blocks
}

bindsym $mod+End exec /bin/bash -c 'i3lock -i <(import -window root - | convert -blur -5x5 - png:-)'
bindsym $mod+b border toggle
hide_edge_borders smart

exec --no-startup-id fcitx
exec --no-startup-id clipit
exec --no-startup-id volwheel

指定终端模拟器程序

# start a terminal
#bindsym $mod+Return exec i3-sensible-terminal
bindsym $mod+Return exec termite

编辑完成后，$mod+shift+c重新加载i3配置
