Good! To make this change more permanent, open the Terminal app.
Run cd /boot/loader/entries
Run ls to see the files in that directory, you will see 1 or more files named such as ostree-eos-1.conf
For each of the files you can see there, open it in the nano text editor, e.g:
sudo nano ostree-eos-1.conf
Use the arrow keys to navigate to the end of the line that starts with options, carefully add the new parameter video=LVDS-1:d
To save and exit, press: Ctrl+O enter Ctrl+X
Please also provide the diagnostic logs mentioned above for each of the computer models that you have found to be affected by this bug. I will then submit a fix to Linux so that you do not need the special parameter in future (and also other Linux distributions would pick up this fix in due course).
