I use gdm3, and I notice that the X server runs on a random console,
which may be 7, 8 or 9.

Here gdm3 doesn't run X, but Xorg:

root 12874 12873  0 Jun20 tty9 00:01:11 /usr/bin/Xorg :0 -br -verbose 
-audit 0 -novtswitch -auth /var/run/gdm3/auth-for-Debian-gdm-AnLrqy/database 
-nolisten tcp vt9

perhaps because it is started by root, thus doesn't need to be suid
like X. So, /etc/X11/xinit/xserverrc isn't used.

Just "vt7"?

But you said it wasn't a specific X variable. If it's the VT number, sure 
it is ;-)

There must a reason for doing that and regardless of its convenience, it 
works fine.

I was not looking for a solution to the OP's problem, I've already said 
that VT is automatically assigned, defaulting to VT7 -as inittab seems to 
say-, and I guess that if it is taken it jumps to the next available. So 
the problem here is knowing why and when it jumps.

It holds vt7.

As I said later in my earlier reply, I gave up on finding out its source...

"FirstVT" used to be an upstream variable but its was dropped in the
upgrade from 2.20 to 2.24 and the Debian maintainer seems to be
applying a patch in order to perpetuate it in Debian.

Anyway, I don't think that this a solution to the OP's problem, unless
I'm misremembering it. No matter what is set as FirstVT, you can end
up at a higher number after logging out and logging back in because
console-kit-daemon would've kept that VT allocated.

I've made some findings. By reading this bug report:

http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=588598

I followed the suggested steps and edited "/etc/gdm3/daemon.conf" (this is 
a wheezey system):

[daemon]
(...)
FirstVT=9

Restarted and seems it worked:

test@debian:~$ grep -i vt /var/log/Xorg.0.log
[37.345] (++) using VT number 9

So at least we have found where we can set this under GNOME.

$@ is a bash positional parameter not an X-specific variable.

I tried to look for its source some time ago and gave up quickly. I'm
not running GNOME so this is from memory: the parent process of "exec
/usr/bin/X ..." calls a variable of the form "/org/gnome/".
I thought that it might be a gconf key that might hold the VT but I
didn't find it.

I've also noticed that time ago under GNOME.

After booting, tty7 holded the X session but after a while it 
automagically jumped to tty8 but I no longer see this behaviour or maybe 
is that just didn't notice again.

I've always thought that X server sets the first available vt for the x 
window system so I wonder why X server cannot dispose of vt7 to allocate 
the kdm/gdm session.

If you run "kill -HUP console-kit-daemon", you can then run "deallocvt
7" and re-use vt7.

It may be worth noting that it is always on 7 when using startx,
instead of a *dm.

I've had the impression that X has been showing up in random consoles ever
