我正在阅读 Arch Wiki，了解如何在挂起时启动屏幕锁定器，但从我的外观来看，我无法light-locker为 LightDM找到工作[email protected]，如下所示：
[Unit]
Description=Screen Locker LightDM
Before=suspend.target
[Service]
User=kevin
Type=forking
Environment=DISPLAY=:0
ExecStart=-/usr/bin/light-locker
[Install]
WantedBy=suspend.target
之后我启用该服务：
# systemctl enable [email protected]
重新启动，但是当我暂停笔记本电脑并再次恢复时，它不起作用，状态[email protected]如下所示：
● [email protected] - Screen Locker LightDM
Loaded: loaded (/etc/systemd/system/[email protected]; enabled; vendor preset: disabled)
Active: inactive (dead)

PD：我light-locker之前在终端尝试过，输入：
$ light-locker --debug
输出：

从另一个终端或只是关闭盖子并恢复，它会向我显示 LightDM 显示屏，用于解锁我的会话
有什么解决方法可以使这项工作正常进行吗？
