After I choose Ubuntu from the GRUB menu which appears on the primary monitor, the login screen appears on the second monitor which is something that I don't want.
How can I prevent this, so that everything appears on the primary monitor?

Ubuntu 18.04 login screen Display settings
Copying the file monitors.xml from /home/user/.config into /var/lib/gdm3/.config/ and
sudo cp ~/.config/monitors.xml ~gdm/.config/monitors.xml
sudo chown gdm:gdm ~gdm/.config/monitors.xml
In /etc/gdm3/custom.conf changing from #WaylandEnable = false to WaylandEnable = false solved the issue.
UPDATE
The same things happen on Ubuntu 20.04 LTS Focal Fossa, gdm somehow does not recognize which monitor is set as primary and the login screen appears on second Monitor.
Copying only monitors.xml solves the issue
sudo cp ~/.config/monitors.xml ~gdm/.config/monitors.xml
