Debian10最小化搭建dwm開發環境

基礎環境

• 選擇安裝發行版：Debian10含非自由固件
• 選擇發行版版本：amd64,standard live

基礎配置
個人開發機為thinkpad x390，debian10 standard版本默認安裝完畢后無wifi相關配置包，需要手動下載wpa_supplicant以及dhcpcd基礎deb，第一次apt update/upgrade需要手動配網

dwm安裝

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

dwm配置

# $HOME/.xinitrc
# 禁止觸控板
xinput disable "Elan Touchpad"

# 解決ibus下chrome無法輸入中文
export GTK_IM_MODULE=xim
export XMODIFIERS=@im=ibus
export QT_IM_MODULE=xim
ibus-daemon -drx

# dwm狀態欄顯示CPU溫度、剩余內存、音量大小、剩余電量、時間
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 &

# 通過startx命令手動啟動dwm
exec dwm
