When you were running Ubuntu 16.04 you were on the Unity interface. After upgrading to 18.04 the Unity interface is still there but new interfaces are offered as well. It sounds like you are searching for the Gnome Desktop which you can select from the “gear” next to the Sign In button during login:
You can try all the desktops to see which you like best but keep in mind:
- Many have reported problems using the Wayland window manager which was designed to replace X11 but has not lived up to expectations.
When I tested 18.04 upgrade of 16.04 clone some of the options resulted in a purple screen with only a movable mouse cursor.
