我最近在笔记本电脑上与Windows 10一起安装了ubuntu18.04LTS。最近（系统更新后），gnome开始随机崩溃。首先，我在Wine上玩一些游戏时就意识到了这一点，因为游戏停止了对任何动作的响应，例如作为keydown或mousemove。然后在使用VLC时会出现提示，但界面没有出现，但是视频却没有。当我使用killall vlc时，它没有用。该界面一直保持到下次启动。现在我使用firefox来浏览网页，会在没有通知的情况下崩溃—侧栏冻结，并且所有窗口的标题栏都消失了，所以我实际上无法控制它们。并且冻结时终端有时不起作用（使用Ctrl + Alt + T无效）
我不使用gnome的任何扩展。
我的硬件：Intel 8265U |显卡-NVIDIA Geforce MX250（实际上不使用，我总是在CPU内使用Intel UHD 620）| teamgroup 16GB DDR4
这是上次崩溃的日志文件。/var/log/apport.log

重要的一点是，这种想法是随机发生的，当cpu使用率较高时，这种情况会更常见，例如打开大文件，在页面上快速滑动或进行游戏。
