I just did a fresh install of Ubuntu 12.04 on a Dell Inspiron 1545, then downloaded & installed all the latest updates. Now when I create a new user postgres in the "User Accounts..." window, it creates the account, but it's not listed in the User Accounts window. Since it's not listed, I am not able to create a password or "enable" the account so they can login.
I have tried reinstalling Ubuntu 12.04 thinking there might have been a bug during installation, but I got the same thing again. Any ideas on how to fix this?
