I strongly disencourage naming the Oracle-softwareowner (or an administrative user for the database) ROOT. This is too easily mixed with the os-administrative user root.
Usually there are some users created during software installation, typically named oracle or oinstall. Use one of these to start dbca.
The errormessage can have several causes - the most common one being the DISPLAY variable set wrong, but if you followed bartus post and used X11-forwarding this variable is already correctly set for you. The second most common one are security settings preventing the connection, which you can switch off with xhost +. A wrong set JAVA_HOME variable is another reasonable candidate to cause this message.
