I just installed the new Ubuntu and I get stuck after I enter my username/password
The screen is in black background and white letters it says:
Ubuntu Precise (development branch) localhost tty1
localhost login: myusername
Password: ********
Everything is okay, next message:
Welcome to Ubuntu...
myusername@localhost:~$_
I tried to type startx but still not working, how do I open the interface? Command?

startx? Is there an error message? What does it say, in the Terminal, when you try to runstartx? – Eliah Kagan Aug 21 '12 at 17:33
