Hi Rob,

Your kernel is 4.2.0-1. So, i suppose you are in Ascii or Ceres...

If you start a X session using a display manager, the virtual console
used by default will be the tty7. However, typing startx the X session
should run in the first virtual console. As you know, you can jump from
tty1 to tty7 typing CTRL + ALT +F7, and vice versa.

The issue, i think, is in the '/etc/X11/Xwrapper.config', provided by
'x11-common' package. Does it contain something like this:

allowed_users=console

or this other one:

allowed_users=anybody

If not, try typing:

# dpkg-reconfigure x11-common

Then choose between the following alternatives:

1- Root Only
2- Console Users Only
3- Anybody

The second and the third options will allow you to start X sessions.

Aitor.
