启动时无法识别外接显示器

Clé*_*ier 5 multiple-monitors hdmi

我不认为自己是 Linux 大师。我不确定我需要提供哪些信息。如果您给我指示,我将很乐意更新我的问题。

设置

HP Spectre x360 - 13-4190nzUbuntu 18.10

办公
笔记本电脑分辨率:2560x1440
第二显示器:迷你显示器到 hdmi,2560x1440主要
第三显示器:hdmi 2560x1440

Home
laptop resolution: 2560x1440
second monitor: mini-display to hdmi, 1920x1080 primary
third monitor: hdmi 1920x1080

Note: I'm not entirely sure if my setup at home is exactly correct. I won't be home before a few days.

Detail of the problem

Whenever it's at home nor at the office, once I pass the login screen, Ubuntu detects only one of my external monitors and the screen is "unstable". The screen starts and stops like it has a bad contact or is badly connected. Once I open the Display Arrangement and change something, it fixes until the next reboot.
