This happened to me also: installing Breezy in expert mode, and giving a
root password, makes Ubuntu NOT adding the first (administrator) user to
sudoers, thus breaking all X application that need root privileges (also
gksudo fails!)

You need adding the "administrator" user to sudoers file yourself:

add a line like:

%admin ALL=(ALL) ALL

to /etc/sudoers (as root, of course)
and check that the "administrator" (normal) user is in admin group (i.e.
listed in the line starting with "admin" of /etc/group)
