环境：我的笔记本是 Ubuntu 18.04LTS，i5-8265U，之前运行正常。
其实我两周前就遇到过这个问题。我进入登录界面，输入密码，然后就闪屏了（屏幕空白，紫色），然后就回到了登录界面---然后我的键盘、触摸板和鼠标就完全不工作了我必须按下电源按钮强制重启。重启后，kryboard 和触摸板运行正常。
我知道我之前问过一些类似的问题。但这与此不同。最后一个问题是当你完成某些任务（例如游戏）时，桌面环境被冻结。这是因为 Xwayland 崩溃并且系统无法重新启动它。 然而，之后我使用了 Xorg 和 gnome。而这次的错误有所不同，因为你可以看到过渡动画，但你什么都做不了，因为你的输入不起作用（键盘等）。
我进入了/var/crash，什么都没有。这里是系统日志在/var/log中。希望它会有所帮助。
