我有一个问题，当我在华硕 E200ha 上插入 vga/hdmi 适配器时，我想启动一个脚本来启动“hostapd”。当我直接在命令行中启动它时该脚本运行良好，但当它被“udev”调用时它不起作用
这是 udev 捕获的行：
ACTION=="change", SUBSYSTEM=="drm", ENV{HOTPLUG}=="1", RUN="/home/user/hotspot.sh"
这是脚本“hotspot.sh”
#!/bin/bash
exec > /var/log/hotplug-vga.log 2>&1;
service NetworkManager stop
killall wpasupplicant
hostapd -dd /etc/hostapd/hostapd.conf &
这是“hostapd.conf”文件
interface=wlan0
ieee80211n=1
driver=nl80211
ssid=chingpro
hw_mode=g
channel=6
ctrl_interface=/var/run/hostapd
ctrl_interface_group=0
当我执行指令“/usr/sbin/hostapd /home/user/hostapd.sh”时，一切正常：
wpasupplicant: aucun processus trouvé
random: Trying to read entropy from /dev/random
Configuration file: /etc/hostapd/hostapd.conf
ctrl_interface_group=0

但是当我连接我的 vga/hdmi 时，我可以看到我的脚本是使用“/var/log/hotplug-vga.log”中的日志执行的，但是“hostapd”的启动失败：
wpasupplicant: no process found

我花了很多时间来了解直接发送此脚本或通过 udev 发送此脚本的区别，但目前没有成功。
我正在做一个全新的“debian buster”安装
我使用相同的脚本安装 Ubuntu 18.04，但我遇到了同样的问题：脚本在命令行中运行良好，但在 udev 启动时失败！
谢谢你的帮助
