Okay, hope you got a good basic install and that your hardware cooperates from here on.
First of all, make sure user and passwords are in order.
As root, use command "passwd" and create one for the root account first.
Next, use "passwd <name_of_user>".
Log in as regular user.
A couple more questions:
- Does X work? You can use command "startx" from command line
- What work environment do you want, IceWM, Openbox or LXDE?
