![ubuntu 19.04 停止工作](https://linux22.com/image/1166696/ubuntu%2019.04%20%E5%81%9C%E6%AD%A2%E5%B7%A5%E4%BD%9C.png)
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。
