Boot straight to Ubuntu Desktop

Hi,
I’m been trying for the last day to remove the login screen on Ubuntu 22.04. I’ve done this
**
Settings->Details->Users and then unlock it with your password and toggle the Automatic Login button off
**
and confirmed by checking /etc/gdm3/custom.conf.
**
AutomaticLoginEnable=True
AutomaticLogin=rock
**
yet I still get the login in screen, and login screen has the Debian logo and colour scheme.

Any Ideas?
