Thank you everyone in advance for help, I am new of the forum

I have a big problem, I canceled something and now when start Kali, I see the black screen and , root and password in strings, some one can help me I have alot of material inside.
This is what I believe to have canceled ( dist )

# apt-get update
# apt-get upgrade
# apt-get dist-upgrade



Upon restart, Kali will not start normally, it appears to me the GUI where just log in, and the desktop!

I get a terminal, where do root login, after I hand in the terminal, where I can also connect to the Internet, but do not you start your desktop!
