12.04 User Accounts not listed in System Settings User Accounts
After incremental updates from 10.10, to 12.04, go back to gnome rather than Unity, and some troubleshooting, I can use my 12.04, but I need to use gdm to "gui"-log into my session (no problem to login via tty). In 11.10, lightdm didn't show my user, but I could specify it and still log in. In 12.04, I had no possibility in lightdm to specify my user. So I found a temp workaround: use gdm as default-display-manager and so I can specify my account to log into Ubuntu. When in System settings/System/User Accounts, my user is not listed (user-id = 601) How could I troubleshoot this ? the goal is to get my account listed in the "gui" list of user accounts, and so go forward to lightdm. Thanks for tips.
