I have 2 monitors on my setup, my primary DELL and a second one (LG model twisted 90º) that I use for references during modeling and OBS for screen recording.
The problem is.
During the boot process LUKS password is showed on primary monitor, what it’s right.
BOOT screen is showed on primary monitor, what is right.
GDM login is in the LG monitor, what is completely wrong and also have the wrong resolution (I manually downscale it to full HD under my session).
After a TAB press and login, DE is set perfectly with my DELL monitor like primary monitor, what is right.
So, how can I manually define GDM to load on my main DELL monitor.
Any deep changes on the system, just a regular workstation install with NVIDIA drivers, and this is not a driver issue by the way.
Regardless of what driver is used, LG monitor IS ALWAYS set like primary during the live media or after the first boot in a fresh install.
