安装步骤

安装显示服务(display server)

pacman -S xorg-server xorg-server-utils

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
yay -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
