自从更新到 19.10 以来，我的 UI 用户体验一直很差。我不确定是 gnome 还是 X，但主要问题是 DE 时不时（大约每 2 天一次）就会崩溃，我丢失了所有会话。我不知道这是否与我的其他问题有关，但当我打开所有应用程序时，UI 非常不流畅，甚至移动蓝牙鼠标看起来也很不流畅。UI 根本没有响应。如果我关闭 IDE 或 Chrome，它会变得更流畅，所以它一定与资源有关。然而，19.04 或 18.10 从未发生过这种情况
这是 GDM 崩溃后我的系统日志的一部分

我认为事故发生在13:00:51因为我试图查看 IntelliJ 中变量的内容，并且有关巨大弹出窗口的警告恰好一致。
有人知道这个错误或如何修复它吗？
据我所知，我的系统中只安装了 3 个 gnome 扩展，都是默认安装的
