Ubuntu 18.04 随机注销黑屏/第二屏幕问题

Ubuntu 18.04 随机注销黑屏/第二屏幕问题

这个问题突然出现了。我在戴尔 Latitude 5591 上运行 Ubuntu 18.04,在断开第二台显示器与 PC 的连接后我注意到了这个问题。

我的 PC 开始随机关机(注销后,屏幕变黑,我必须按下电源按钮才能再次运行,并且会提示我输入密码),每隔 30 秒或更短时间,分辨率就会变得有点混乱,如果我转到“设置”中的“显示”,它会提示“无法获取屏幕信息”。此外,每次我插入外接显示器时,外接屏幕上的所有内容都可以正常工作,但笔记本电脑上的屏幕却不行。

我尝试了在线上能找到的大多数解决方案,但没有什么真正帮助。

谢谢您的帮助 :)
