I have installed i3 and logged in by using i3 as GUI/Window Manager. Now, whenever I start Ubuntu, it automatically logs into i3. How can I go back using Unity as GUI? I am using Ubuntu 18.04.

Edit /etc/gdm3/custom.conf
and comment the two lines:
AutomaticLoginEnable=True
AutomaticLogin=Foo
Restart, and you should see the login screen again where you can choose the GUI/WM to be used.
dpkg-reconfigure
andupdate-alternative
as suggested in the answer I linked to?
