我不认为自己是 Linux 专家。我不确定我需要提供什么信息。如果您给我说明，我将很乐意更新我的问题。
设置
惠普 Spectre x360 - 13-4190nz和Ubuntu 18.10
办公室
笔记本电脑分辨率：2560x1440
第二台显示器：迷你显示器转 HDMI，2560x1440基本的
第三台显示器：hdmi 2560x1440
家
笔记本电脑分辨率：2560x1440
第二台显示器：迷你显示器转 HDMI，1920x1080基本的
第三台显示器：hdmi 1920x1080
注意：我不确定我在家里的设置是否完全正确。几天后我才会回家。
问题细节
无论是在家还是在办公室，一旦我通过登录屏幕，Ubuntu 只会检测到我的一个外接显示器，并且屏幕是“不稳定“。屏幕开始和停止，就像接触不良或连接不良一样。一旦我打开陈列布置并进行一些改变，它会修复直到下次重启。
