OK cool so let's pick a DM and get it working. We can ignore the video
group permissions etc. Sounds like lightdm is currently installed and
'working' we'll just poke at it's settings.

Apparently lightdm defaults this way. See links below.

Here's some relevant stuff you may have bumped into:
https://askubuntu.com/questions/62564/how-do-i-disable-the-guest-session#62566
Which lead me here:
https://wiki.ubuntu.com/LightDM

I think we should try this one:
https://wiki.ubuntu.com/LightDM#Allow_Manual_Login
Edit the lightdm config file probably /etc/lightdm/lightdm.conf but if
that's not seeming to take effect note the list of cascading conf files
from the top of that page.
To include:
[SeatDefaults]
greeter-show-manual-login=true

also note the info at the top of that page about later versions of
lightdm changing the syntax from SeatDefaults to Seat:*

After each change you try do:
$sudo /etc/init.d/lightdm restart

If I'm guessing right. That should get you a lightdm login page. And
hopefully actually logging in will work from there. If not we're
probably back to Ted's idea that there's some setting in your user
account. We can probably traack it down with logs or something. Maybe
/var/log/lightdm
