Question

我使用Linux Mint19。我创建了一个简单的脚本“ After_suspension”，它将运行三个命令。我正在尝试让Mint从暂停状态中唤醒时运行它。

matthew@matthew-pc:~$ cat /usr/local/bin/After_suspension
#!/bin/bash
pon dsl-provider
sudo service fancontrol start
/usr/bin/mailnag

matthew@matthew-pc:~$ file /usr/local/bin/After_suspension
/usr/local/bin/After_suspension: Bourne-Again shell script, ASCII text executable

“ mailnag”为(text/x-python)。我创建了以下服务文件，该文件已启用但失败。如何运行？我应该使用三个单独的服务文件来运行这三个命令吗？

matthew@matthew-pc:~$ cat /etc/systemd/system/After_suspension.service
[Unit]
After=suspend.target

[Service]
ExecStart=/usr/local/bin/After_suspension

[Install]
WantedBy=suspend.target
matthew@matthew-pc:~$ systemctl is-enabled After_suspension.service
enabled
matthew@matthew-pc:~$ systemctl is-active After_suspension.service
failed

matthew@matthew-pc:~$ systemctl status After_suspension.service

以下是当前的“ fancontrol.service”。

matthew@matthew-pc:~$ cat /lib/systemd/system/fancontrol.service
[Unit]

Systemd以root身份运行系统脚本，因此您试图在没有X服务器活动的终端会话中以root身份启动GNOME磁盘，这就是为什么您可能会收到连接被拒绝消息的原因。

您可能希望将该服务配置为用户服务（您也可能必须传递DISPLAY变量），或者只是首先尝试在任一脚本中设置DISPLAY变量或系统服务。

服务已启用但失败。如何运行？
