我一直遇到 Manjaro 上的 i3 中无法加载通知的问题。
这会导致通知图标无法正常工作的奇怪问题。例如，当我单击网络管理器时，它不会显示菜单。Discord 会随机挂起，或者我的会话会在随机时间冻结。
我看到以下内容：
journalctl -b | grep -i notification

我发现对我有用的是manjaro 论坛
systemctl --user start xfce4-notifyd
systemctl --user status xfce4-notifyd
systemctl --user enable xfce4-notifyd
但这对我来说不是一个永久的解决方案。它的状态从linked变为enabled
systemctl --user status xfce4-notifyd
