+问题：

+
+环境：
+    hyprland (kde 下无此问题)
+    hybrid (独显直连没有测试)
+
+结论：
+    罗技 Bolt 接收器导致的
+
+解决1：
+    修改 /proc/acpi/wakeup 禁用 usb 唤醒
+    修改什么？问 LLM 吧，现在的我也不知道 :)
+
+解决2：
+    安装 solaar 并启动
+    步骤：
+        创建 plugdev 用户组：
+            sudo groupadd plugdev
+            sudo usermod $(whoami) -aG plugdev
+        安装 solaar
+        启用驱动：
+            sudo modprobe hid_logitech_dj
+        重载 udev 规则：
+            sudo udevadm control --reload-rules
+        插拔 Bolt 接收器
+        启动！

+当安装了其他 notification manager 时，plasma 在启动时可能会选择错误的 notification manager 导致通知中心无法正常工作 <s>(虽然平时也并不怎么在意这玩意，用什么 daemon 都无所谓，只要有通知看就行)</s>
+
+如何知道是否是这种情况呢？以 mako 为例：
+
+1. 先知道 mako 是什么时候被启动的 (或者自己推算时间)：
+   ```sh
+   journalctl --user -u mako.service --no-pager -g 'Starting'
+   ```
+2. 查看先后的日志：
+   ```sh
+   journalctl --user --since '2025-07-29 00:43:16' --until '2025-07-29 00:43:18'
+   ```
+3. 如果发现类似以下内容：
+   ```

+   Jul 29 00:43:17 Artemisia systemd[1080]: Started Lightweight Wayland notification daemon.

+   Jul 29 00:43:17 Artemisia plasmashell[1599]: org.kde.plasma.notificationmanager: Failed to register Notification service on DBus
+   ...
+   ```
+   那就是这种情况了。
+
+解决方法也很简单，启动时屏蔽掉错误的服务，例如：
+
+```sh
+systemctl --user mask mako.service
+```
+
+或者将 plasmashell 的 notificationmanager 优先级提高：
+
+```sh
+mkdir -p ~/.local/share/dbus-1/services/
+ln -s /usr/share/dbus-1/services/org.kde.plasma.Notifications.service ~/.local/share/dbus-1/services/org.kde.plasma.Notifications.service
