[Ethereal-users] Xlib: connection to ":0.0" refused

[Nelly Pernot <nelly.pernot@xxxxxxxxxxxx>]

When I logged as root, I have no problem to run ethereal.
But when I logged as user, I open a shell by "su" or "su -" and run 
ethereal, I obtain this error message:

Xlib: connection to ":0.0" refused by server
Xlib; Client is not authorized to connect to Server

Gtk-Warning **: cannot open display: :0

I work on a debian 3.0

What can I do
Thanks
