I think the present problem, which I can still reproduce on my Sid system,
is not related to #348033.

I find that VT7 often cannot be deallocated after X shuts down, which
explains why X has to use VT8 if started up again:

# deallocvt 7
VT_DISALLOCATE: Device or resource busy
deallocvt: could not deallocate console 7

Killing console-kit-daemon makes VT7 available again for me in this
situation, and X starts normally after that. I have not bothered to
investigate this issue any further.

Well, Florian, after today's upgrade I am now where you are with Sid.
The X server is on vt7, I logout of the GNOME desktop, and X restarts
on vt8. I switch to a text console, issue "deallocvt 7", and it fails.
I kill console-kit-daemon, then "deallocvt 7" is successful. Another
logout from the GNOME desktop and the X server starts up on vt7.
(console-kit-daemon restarts as soon as I switch back to the X console).

I came across a long-standing issue with the daemon running in 64
threads, maybe the present annoyance is related. The report gives me the
impression that some kludges are currently used for the daemon's
interaction with the VTs:
