Can GDM allow passwordless logins for specified users, in Ubuntu?

Sorry I cannot offer a HOWTO, but I do want to suggest a point of
consideration. Ubuntu uses "sudo" for administration with no root
password by default. I'm not sure that removing the user password would
be such a good idea. I suppose you could create a root password and then
go about using the method you described.

I hope someone has a better anwser to your problem, I just wanted to
discourage you from removing the only password on your system if root
has no password (which it does not by default).
