我的笔记本电脑运行的是 Ubuntu 19.04，现在遇到了一个奇怪的问题。从今天早上开始，突然间，我的笔记本电脑在出现一系列症状后停止工作，例如亮度增加到最大级别（我更喜欢在低亮度下工作），然后笔记本电脑键盘停止工作。我可以在屏幕上移动光标，但点击不起作用）。为了解决这个问题，我取出电池，然后再次重新启动笔记本电脑。我不明白为什么会发生这种情况。笔记本电脑硬件有问题还是 Ubuntu 有问题？我真的需要帮助，因为现在每 2-3 小时就会发生一次。谢谢。
问题发生时/var/log/syslog的部分数据如下：

我已经看到许多与此错误消息相关的问题。包括从睡眠状态唤醒缓慢。屏幕重绘时长时间暂停。应用程序启动时间长。我发现唯一可靠的解决方法是完全清除 gnome-shell-extension-appindicator 包并重新启动。然后系统会再次正常响应。我不知道这个扩展提供了什么视觉效果，所以我当然可以不用它。遗憾的是它是默认安装的。
