我在 KDE 上进行了全新安装，刚刚安装了 touchegg，但似乎无法让它工作。我按照安装说明复制了默认配置文件，但即使重新启动后也没有任何反应。我尝试使用 --daemon 标志对其进行调试，但出现以下错误：
$ touchegg --daemon
Touchégg v2.0.5.
Usage: touchegg [--daemon [start_threshold finish_threshold]] [--client]
Multi-touch gesture recognizer.
Touchégg is an app that runs in the background and transform the gestures you make on your touchpad into visible actions in your desktop.

Option Meaning
--daemon Run Touchégg in daemon mode. This mode starts a service that gathers gestures but executes no actions
--client Connect to an existing Touchégg daemon and execute actions in your desktop
Without arguments Touchégg starts in client mode

A list of detected compatible devices will be displayed below:

what(): Error initialising Touchégg: libinput open.
Touchégg should be run in daemon mode by systemd in order to be part of the 'input' group and have access to your touchpad.
If you prefer to run Touchégg without using systemd, please execute the following command:
$ sudo usermod -a -G input $USER
And reboot to solve this issue
Aborted (core dumped)
另外，尝试在客户端模式下运行它也不起作用，它似乎无法连接到守护进程，它一直失去连接：

触控板可以正常工作，系统中的其他部分似乎都没有损坏，任何输入信息都将不胜感激！我猜是因为某种原因守护进程无法启动。
