Xorg replaces TTY1

[berenger.morel@neutralite.org]

Hello.

There is a behavior change I noticed when I switched to Jessie, which 
have always annoyed me but that I never tried to resolve.

The change is that now, when I use startx on TTY1, Xorg replaces the 
TTY. I understand that it is not a problem for 99% of users, but I would 
like to know how to configure Debian to stay with the old behavior (aka: 
start Xorg on TTY 7+).
Do someone have any clue about how to do that?

Thanks.
