daric,
Do you remember your password for your root account? If so login into a terminal and type useradd add a new user and password and use that.
IF YOU HAVE FORGOTTEN THE ROOT PASSWORD
what bootloader are you using? I know in Lillo you can just go CTRL + X, this will send you to the Boot prompt then type Linux single, this will change you to root without a password and then type passwd and change it login and create a new user as discribed avove
In Grub When you are presented with the Grub menu, hit the 'e' key. This will allow you to edit the current boot options. Add the ' single' to the line that begins with 'kernel /vmlinuz'. Now press 'b' to boot with the modified boot options.
You'll now be presented with the command line. At the command line simply enter 'passwd'. You'll be prompted, twice, for a new password.
Type in 'exit' and the machine will continue booting into the normal process. Your root password has now been changed.
Or backup your data using Knoppix Live and then do a reinstall
hope this Helps
