linux - 网络管理器调度程序脚本无法重新启动很棒的 wm

Question

我希望当网络环境改变时，awesome wm 能够以不同的配置运行。因此我在网络管理调度程序中编写了一个脚本，以便当网络环境发生变化时执行该脚本；

#!/bin/bash
# Restart awesome through awesome-client

USER=dreamingo

awesome_restart(){
    /bin/su $USER -c "echo 'local awful = require (\"awful\"); return awful.util.restart()' | awesome-client"
}

#To check the cable insert or not
wire_insert_state=$(cat /sys/class/net/eth0/carrier)
#Check which config the current awesome taking(wired or wireless)
current_config=$(cat ~/.config/awesome/flag)

# if [[ $wire_insert_state = 1 ]] && [[ $current_config == "wireless" ]];then
if [[ $wire_insert_state = 1 ]];then
    cp /home/dreamingo/.config/awesome/rc.lua.wire /home/dreamingo/.config/awesome/rc.lua
    echo wired > ~/.config/awesome/flag
    awesome_restart

# elif [[ $wire_insert_state = 0 ]] && [[ $current_config == "wired" ]];then
elif [[ $wire_insert_state = 0 ]];then
    cp /home/dreamingo/.config/awesome/rc.lua.wireless /home/dreamingo/.config/awesome/rc.lua
    echo wireless > ~/.config/awesome/flag
    awesome_restart
fi

但是，当环境发生变化时，这个脚本确实会运行，但 Awesome wm 不会重新启动。

我认为这是脚本由root执行的原因，因此我使用以下命令:

/bin/su $USER -c "echo 'local awful = require (\"awful\"); return awful.util.restart()' | awesome-client"

当我su到root时，这个命令将起作用(重新启动很棒的wm)；但是，当我使用时:

sudo ./02check_wireless    #02check_wireless was the name of the script

运行脚本，脚本失败重启wm；但是当我以当前用户(dreamingo)身份运行它时，它就可以工作；

而且，无论是上述结果(成功与否)，脚本都会输出:

Error org.freedesktop.DBus.Error.ServiceUnknown: The name org.naquadah.awesome.awful was not provided by any .service files

我以为失败的也尝试重新启动真棒，但有东西覆盖或阻止它......

当我以 root 身份运行它时，这个变体对我来说效果很好，具有很棒的 3.5.5

#!/bin/bash
# Restart awesome through awesome-client

USER=my_username_here

awesome_restart(){
    /bin/su $USER -c "echo 'awesome.restart()' | awesome-client"
}

awesome_restart
