When reading the thread "Lockups after unlocking screensaver", it reminds me an unanswered question I had months ago.
I use Trinity 3.13.2 on Ubuntu 12.04 LTS. As far as I can recall (years), my TDE session started on vt7 (Ctrl-Alt-F7). After a power outage, I restarted my box and ever since TDE starts on vt8 (Ctrl-Alt-F8). Everything works well but I would like to understand the reason of this vt switch. I searched the web for an answer with no success. Does someone on this list has an answer?
Nothing harmful, no bug, but curiosity... is on mars now :-)

I'd look for stale Xorg lockfiles in /tmp; if Xorg "thinks" there's a session already active on VT7 it will start the next one on VT8. This isn't an issue on boxes where /tmp is mapped to tmpfs, but I know there are people who like to map /tmp to persistent storage so I thought I'd mention it.

Thanks for this quick and interesting reply Tim.
Actually my /tmp is mapped to tmpfs so I assume it is cleared on each reboot. There should not be any lock surviving a reboot in this configuration. This is why I am so curious on what caused the vt switch - and how to revert it -.
The X server shows:
$ ps -ef | grep X root 1301 858 2 12:47 tty8 00:02:58 /usr/bin/X -br -nolisten tcp :0 vt8 -auth /var/run/xauth/A:0-uTXGia
So X is clearly started with the "vt8" param but I do not know enough about X management to find out which process provides the param.
I think I found a hint on what is happening while booting: If I do a [Ctrl]-[Alt]-F7 after a fresh boot while [Ctrl]-[Alt]-F8 shows the login screen, the vt7 shows the Ubuntu Splash screen with the message "Waiting for network for another 60 seconds..." (I do not remember the entire message though) so it looks like TDE tries vt7 first and switches to vt8 because there is something wrong in vt7 (my guess). I have no clue on what could be wrong for vt7 and right for vt8 on the same box!
Still searching...

Are you sure you even checked since long ago until now? My *buntu login managers have been running on vt8 at least as far back as 14.04.

I noticed the vt8 change as soon as I restarted the box after the power outage. However, I am far to be back to Ubuntu 14.04 since I am on 12.04.., I think I would have to upgrade first :-) But yes, I am sure of the fact.

Mine runs on VT8 and has done from day one !

Further back than that! Here Ubuntu 10.04 and Trinity 3.5.13.2 (Like Uwe Brauer says: "because it works[")

AFAIK, most dm's are setup to start X on the first free vt, so you should probably look not into TDE configuration, but rather for something that grabs vt7 prior to TDE start.
