disabled

I'm working on a setup like this: laptop + connected external screen through
hdmi. As my external screen is ultra wide i do not want/need to use laptop's
screen.
To use only connected screen i'm trying to configure it in System Settings ->
Display & Monitor -> Display Configuration as follow (see attached screenshot
nr 1):
1. Primary display: HDMI-1
2. Laptop Screen (LVDS-1) -> Display [Enabled] unchecked
3. Apply settings
4. Both screens get turned off
Than after this changes when i had both screens OFF and i unplugged hdmi cable
from my laptop it's screen (laptop) turned ON. After that i plugged in hdmi
cable again and external screen was also ON.
With this screens problem i noticed also panel issue. I was using single panel
on external screen. After hdmi cable was unplugged the panel was moved to
laptop screen. After conecting hdmi cable again, panel was rendered like 80% on
laptop screen and 20% on external screen (see attached screen nr 2).
Reproducible: Always
Steps to Reproduce:
1. Have 2 screens setup (laptop + external in my case)
2. Configure through System Settings one screen (laptop in my case) to be
disabled and set the connected one as a primary display.
3. Apply changes and observe like both screens are turning off
Actual Results:
When disabling main (laptop) screen than also external screen gets
disabled/turned off.
Expected Results:
When disabling main screen only this on shoudl be disabled and external one
shoudl work.
