First of, let me tell you I'm a n00b at ubuntu. I have updated my Ubuntu mediacenter to a later version of ubuntu, currently at 12.04. I'm working through a lot of updates to get to the latest. But since my first update I got the new login screen (lightdm?) and my autologin wasen't working anymore. So I Googled how I could make lightdm autologin. I've managed this by making my /etc/lightdm/lightdm.conf look as follows:

[SeatDefaults]
greeter-session=unity-greeter
user-session=ubuntu
autologin-user=my_user
autologin-userutologin-user=-timeout=0

Which seemed to work... But now that it automatically logs in, I seem to get the following type of screen (through nomachine remote desktop client):

Sorry... I am unable to post my screenshot here because I do not have the 10 reputation points in askubuntu yet.... darn it...

But the screen has a terminal at the top left of the screen (not an actual "window"), and the ubuntu loading screen is still behind it.

I've tried running startx as you can see. But, this seems to actually be x server. But if I run unity --reset, it seems that a lot of the desktop gets restored, but... with a lot of errors and warnings and the next time I boot, it's the same story all over again. Also, when I close the terminal window after getting my desktop back, I get thrown back at the login screen.

Please bear with my lack of knowledge of ubuntu and it's underlying unix. I thank you in advance.
