前言

ubuntu系统默认安装的桌面环境是gnome，但是我想换一个窗口管理器，主要是为了好玩，如果能将桌面改造的好看一点就更好了。因此我希望选择一些高定制的窗口管理器，例如i3wm，hvwm，awesome等，桌面环境不变。最后肯定是像标题说的那样选择了i3wm，因为awesome配置比i3wm复杂一些，i3wm也比awesome主流一些，至于hvwm，这个用的人更少了，而且这个窗口管理器也很少更新，所以暂时选择i3wm练手。

i3wm的安装

i3wm的安装比较简单，我主要安装了xfce4，i3和lightdm（登录管理）

sudo apt-get install xfce4
sudo apt-get install i3
sudo apt-get install lightdm

经过配置后的桌面效果大致如图所示：

i3wm的配置

i3wm快捷键配置介绍

设置windows键为mod键，i3wm中默认Mod1为Alt，Mod4为windows键，如果想让windows键为mod键，可以在配置文件前加一句：set $mod Mod4。我是直接用Mod4配置的一些快捷键。以下是一些常用的快捷键：

win+d:打开dmenu
win+Enter:新建一个Terimal
win+f:窗口全屏
win+r:存在多个窗口时，调整窗口大小
win+t:新建窗口有标签栏
win+y:新建窗口有边框
win+u:新建窗口无标签栏无边框
win+num:跳转到工作区num
win+h:光标移到右边的窗口
win+j:光标移到下面的窗口
win+k:光标移到上面的窗口
win+l:光标移到左边的窗口
win+Shift+num:将当前窗口转移到工作区num
win+Shift+h:将光标所在的窗口移到右边
win+Shift+j:将光标所在的窗口移到下面
win+Shift+k:将光标所在的窗口移到上面
win+Shift+l:将光标所在的窗口移到左边
win+Shift+r:重启i3wm
win+Shift+c:重新加载i3wm配置文件
win+Shift+e:退出i3wm
win+Shift+q:关闭当前窗口
win+Shift+f:打开firefox浏览器
win+Ctrl+h:下一次新建窗口时，水平分割窗口
win+Ctrl+v:下一次新建窗口时，垂直分割窗口
Fn+volume+:加音量
Fn+volume-:减音量
Fn+volumemute:静音

i3wm配置文件

i3config

# i3 config file (v4)
#
# Please see https://i3wm.org/docs/userguide.html for a complete reference!
#
# This config file uses keycodes (bindsym) and was written for the QWERTY
# layout.
#
# To get a config file with the same key positions, but for your current
# layout, use the i3-config-wizard
#

# 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.

# use these keys for focus, movement, and resize directions when reaching for
# the arrows is not convenient

xcompmgr是一个使终端半透明的插件。（gnome自带的Terimal也可以设置透明效果）

feh是一个图片查看工具，也可以设置壁纸。

i3status_config

i3status是桌面顶端的长条状态栏（默认在桌面下方，可设置为上方）

# i3status configuration file.
# see "man i3status" for documentation.

# It is important that this file is edited as UTF-8.
# The following line should contain a sharp s:
# ß
# If the above line is not correctly displayed, fix your editor first!

general {
        colors = true
		color_good = "#1793D0"
		color_degraded = "#006298"
		color_bad = "#FF00FF"
        interval = 5
}

# order += "ipv6"
order += "disk /"
order += "wireless _first_"
order += "ethernet _first_"
order += "battery all"
order += "load"
order += "tztime local"

wireless _first_ {
        format_up = "W: (%quality at %essid) %ip"
        format_down = "W: down"
}

ethernet _first_ {
        # if you use %speed, i3status requires root privileges
        format_up = "E: %ip (%speed)"
        format_down = "E: down"
}

battery all {
        format = "%status %percentage %remaining"
#        format = "%status %percentage"
}

tztime local {
        format = "%Y-%m-%d %H:%M:%S"
}

load {
        format = "%1min"
}

disk "/" {
        format = "%avail / %total"
#        format = "%free / %total"
}

随机壁纸

我自己写了一个比较简单的脚本来从我的壁纸库中随机抽取一张图片作为我的壁纸。因为我壁纸库里的图片都是我自己从网上下载的一些我比较喜欢的图片，因此下载的时候我把图片都命名成了wallpaper+数字+后缀名的形式（wallpaper01.jpg），这样方便我写脚本。目前我壁纸库里有九张壁纸，编号从01-09，所以我新建一个wallpaper.sh的脚本文件，内容如下：

#!/bin/bash

N=9
var=wallpaper0$[RANDOM%$N+1].jpg
feh --bg-fill ~/Pictures/wallpapers/$var

然后我在我i3的config文件中写入以下两条命令:

bindsym Mod4+Shift+p exec bash ~/Pictures/wallpapers/wallpaper.sh
exec_always --no-startup-id bash ~/Pictures/wallpapers/wallpaper.sh

这样我每次开机或者按下win+Shift+p就会运行wallpaper.sh这个文件，并为我选取一张幸运壁纸。

亮度调节

我安装了一些插件像xbacklight，xfce4-power-manager等，但是都不好使。但是想调节亮度的话也是有办法的。

# 查看电脑的最大亮度值，我的是800多。不同电脑max_brightness的路径可能不一样，但是一般都在/sys/class/backlight/里面
cat /sys/class/backlight/intel_backlight/max_brightness
# 设置你认为合适的亮度值
sudo tee /sys/class/backlight/intel_backlight/brightness <<< 100

本来写了个脚本来调节亮度，但是绑定键位不成功，也不知道为什么，不过脚本还是可用的。

# ========================= brightnessUp.sh==============================
#!/bin/bash
var1=+50
var1=$(($var1 + $(cat /sys/class/backlight/intel_backlight/brightness)))
sudo tee /sys/class/backlight/intel_backlight/brightness <<< $var1
# ========================= brightnessDown.sh==============================
#!/bin/bash
var1=-50
var1=$(($var1 + $(cat /sys/class/backlight/intel_backlight/brightness)))
sudo tee /sys/class/backlight/intel_backlight/brightness <<< $var1

ranger文件管理器

对，下面这个图就是ranger，它可以帮你很快的预览文件
ranger 可以预览文本文件的内容
wallpaper.sh 也可以打开图片
刚开始ranger打开图片大小可能不合适，需要你手动去调节（按上下键）。但是我觉得这样太傻了，如果你想让你的ranger打开图片时像上面那样，刚好可以看清整张图片，你可以修改ranger的配置文件。将图片打开尺寸设置为你电脑屏幕分辨率的一半就可以了。

ranger --copy-config=all
cd ~/.config/ranger
vi rifle.conf

将rifle.conf里的mime ^image, has feh, X, flag f = feh -- "$@"修改为
mime ^image, has feh, X, flag f = feh -g 683x384 -- "$@"
因为我电脑屏幕的分辨率为1366x768，所以我设置683x384。
