Debian10最小化搭建dwm开发环境

基础环境

• 选择安装发行版：Debian10含非自由固件
• 选择发行版版本：amd64,standard live

基础配置
个人开发机为thinkpad x390，debian10 standard版本默认安装完毕后无wifi相关配置包，需要手动下载wpa_supplicant以及dhcpcd基础deb，第一次apt update/upgrade需要手动配网

dwm安装

sudo apt install libx11-dev libxft-dev libxinerama-dev xorg

dwm配置

# $HOME/.xinitrc
# 禁止触控板
xinput disable "Elan Touchpad"

# 解决ibus下chrome无法输入中文
export GTK_IM_MODULE=xim
export XMODIFIERS=@im=ibus
export QT_IM_MODULE=xim
ibus-daemon -drx

# dwm状态栏显示CPU温度、剩余内存、音量大小、剩余电量、时间
while true
do
        CPU=$(sed 's/000$/°C/' /sys/class/thermal/thermal_zone0/temp)
        MEMORY=$(free -h | awk '(NR==2){ print $7 }')
        VOL=$(amixer get Master | awk -F'[][]' 'END{ print $2 }')
        CHARGE=$(cat /sys/class/power_supply/BAT0/capacity)
        DATE=$(date "+%a %d-%m-%y %H:%M")

        xsetroot -name "CPU:$CPU|MEM:$MEMORY|VOL:$VOL|BAT:$CHARGE%|$DATE"
        sleep 3s
done &

# 通过startx命令手动启动dwm
