How do I make GDM the default display manager?

lightdm gdm display-manager

You seem to have configured gdm correctly, but you did not actually stop lightdm. Logging out doesn't stop it.

After doing sudo dpkg-reconfigure gdm, you need to stop lightdm

sudo service lightdm stop

and start gdm

sudo service gdm start

Hope this helps.

I believe my question says what I am trying to achieve.

Steps I tried to make gdm my default display manager:
1. sudo dpkg-reconfigure than select gdm as my default.
2. Edit /etc/X11/default-display-manager and change its content to
```
/usr/sbin/gdm
```
After the above two steps I logged out myself and after that when I see my login screen it still shows lightdm as my display manager.

What am I doing wrong here.?

Note: This kills the session. Stopping the a display manager while running a desktop session will also kill your desktop environment.
