I have installed Kali linux 64 bit in my Oracle VB.
I have allocated 1 Gb of RAM, 35 Gb of Hard disk to it.
After apt-get upgrade, I was logged out and could not log in again.
I powered off my VB and restarted it. Now whenever I log into my Kali, I can only see a blue screen.
If I try to open a terminal, I am getting routed back to login page.
