我创建了服务，但它显示不活动（已死）

Question

这与其他主题的问题不同。我试图在我的 ubuntu 上创建一个服务，但它一直说这个服务不活动（死）。

我的操作系统：

我的服务（在 /etc/systemd/system/resume.service ）：

[Unit]
Description=Run commands after resume from suspend
After=suspend.target

[Service]
ExecStart=/bin/sh /usr/local/bin/resume.sh

[Install]
WantedBy=suspend.target

我的 shell 脚本（在 /usr/local/bin/resume.sh ）：

#!/bin/sh

# Workaround for XFCE bug re black screen on resume from suspend:
# if a user is logged into an X session via xfce, run 'xrandr --auto' to restore default display.

for id in $(loginctl list-sessions --no-legend | awk '{ print $1 }')
do
    s="$(loginctl show-session "$id")"
    if printf "$s" | grep -q 'Display=:0'
    then
        if printf "$s" | grep -q 'Desktop=xfce'
        then
            u="$(printf "$s" | grep 'Name=' | cut -d'=' -f2)"
            DISPLAY=:0 su "$u" -c 'xrandr --auto'
            exit
        fi
    fi
done

我试过这些命令但我无法激活该服务：

sudo systemctl enable resume.service
sudo systemctl start resume.service

在我运行 $sudo systemctl statusresume.service 之后:

○ resume.service - Run commands after resume from suspend
     Loaded: loaded (/etc/systemd/system/resume.service; enabled; vendor pres>
     Active: inactive (dead)
