Received the following response from A Raghuram (araghuramindia) to the
question (#672572) that I posed:
"See if the following steps help you:
1) Choose recovery mode from the GRUB menu
2) Choose resume normal boot from the recovery menu
3) If you are able to get the login screen,
after logging in, uncomment the line "WaylandEnable=False" statement in the
"/etc/gdm3/custom.conf" file and save it
4) Then restart for a normal reboot.
I had the same problem with a non-Dell desktop computer and the above
steps solved it."
This work-around also allows the computer to boot normally.

Title:
A Dell Optiplex will not reboot after a fresh install of Ubuntu 18.04.
Status in lightdm package in Ubuntu:
New
Bug description:
Installed Ubuntu 18.04 on a Dell Optiplex but after the withdrawal of
the flash drive and pressing enter to reboot the computer, the
computer screen froze just before the login appeared. The
installation was repeated with five different flash drives with both
Ubuntu 18.04 and Ubuntu 18.04.1. The same result occurred each time.
After some research, it was discovered that the LightDM has been
replaced as the default login display manager by GDM3 which apparently
is a lot heavier. Although the Dell Optiplex is over ten years old it
still meets the minimum requirements for the installation of Ubuntu.
It will install and reboot after installation of all of the Ubuntu
"flavors" [Kubuntu, Ubuntu Mate, Ubuntu Budgie, Xubuntu, and Lubuntu]
as well as Ubuntu 16.04.4. If a computer meets the minimum install
requirements it should be able to install Ubuntu. As a work around
the LightDM was installed and made the default login display manager.
That works as expected. Is the new default login display manager to
heavy for some computers to load?
