New install of 12.04.1 and the user established during install cannot login.
I was able to create an new user by entering the system as guest. Ubuntu accepted the sudo password of the first user to establish the new user; but I cannot login as the user established during install. The newly created user does have admin permission and I can login using that user and do sudo stuff.
What happens when I try to login as the user established during install is some text flashes on the screen so fast I cannot read it and then I'm returned to the login screen.
I am dual booting with Ubuntu 10.04 LTS and 12.04 LTS. Both of those share the same /home mount point and the user established in 12.04 has th esame credentials as a user on 10.04 - which works fine.
