Public bug reported:

I have experienced a stubborn issue after upgrading my Ubuntu from 18.04
to 18.10. Every time I would like to login into my system via lightdm
the login process takes a lot of time (more than 2 minutes). This is
definitely an issue because this process took about half minutes in my
previous version of Ubuntu. The issues is affected both GNOME and XFCE.

I have tried resolve issues provided by journalctl but I did not found
solution regarding most of those problem. I am sure this problem affects
many users. I have been searching solution and also workaround such as
install another desktop environment would be appreciated.

I have tried

 - removing xdg-desktop-portal
 - removing gnome-keyring

Both of them issued error.

 - reinstall lightdm

None of them was successful.
