Do you have the /etc/logindevperm file with the entries listed above ?
/dev/vt/7 is owned by you, and /dev/vt/console_user is linking to that,
so those entries should work. These are used by the login process, or
gdm. If you use lightdm, I'm not shure if that supports logindevperm
(somewhere the "light" has its origin ...).
