This question is a 2 part question (I know there is already a question on GDM):
When I create a new user that person shows up on the login screen for Kubuntu 12.10 however I would like to hide that user so he/she doesn't show up. This has happened for several service type accounts I've created that I want to hide. The other user case would be a shared computer where I would want my wife's user and my son's user to show up, but my user (the admin account) to be hidden. So is this possible?
Follow up to that question, if there is a way to hide that user from login, how would I go about logging to such user?
Thanks in advance,
Jonathan
