Lightdm - autologin not working

When trying to use autologin feature it will not log me in when the computer starts up.
However, if I login as root and restart the lightdm service it logs me in automatically.
Whats up with that ?
This is my lightdm.log when I just boot my computer and it won't automatically log me in:

And this is lightdm.log when I as root do a: systemctl restart lightdm.service
and it works as it should. Ie logging me in automatically.

And the same exact thing happens with GDM.

Do tell if you want more logs.

Re: Lightdm - autologin not working

I think you should be able to enable auto login via your display manager.  Try logging in 'manually'  and navigate to the user account settings and select auto-login.  Have you enabled 'lightdm.service' ?

The service is enabled, otherwise it won't start lightdm at boot.
And clicking auto-login in gnome makes no difference.

Defo some (user? wayland?) related weirdness going on - what do your lightdm.conf and greeter conf look like?

Haha. I was editing it out but then I thought about human error and that I might delete something important for debugging

Yup, my user is really shell.
Easier to type than theailer
