adsl and xemacs (beginner)

["Kapil Khosla" <khoslakapil@lycos.com>]

Hi, I am a beginner and have 2 questions:
1) I configured my DSL from Verizon from root, by using the Roariing
Penguin software but when I go to my user account I am not able 
to connect as I dont have the adsl-start utility.
Will I need to redo the process I did for root for every user account
i create ?
2) I used apt-get install xemacs and got the editor but am not able
to open it from console (xemacs &),I get the follwing error
Xlib: Client is not authorized to connect to Server

Initialization error: X server not responding
: ":0.0"

[1]+  Exit 255                xemacs

I can however use it from the Apps-Editor-Xemacs
Why is this so..can you give me a web resource to understand the \
reason,
Thanks ,
Kapil
