I have just installed kali 2.0 on a usb key and setup persistence to keep my data.
It was booting and I was able to access to the gui.
I decided to run some commands to update kali:
Code:
apt-get update && apt-get upgrade && apt-get dist-upgrade
It works and after a
Code:
reboot
, kali could not pass the boot sequence...
It stopped there and continuously turn the screen on and off, always showing the same sequence:

The problem is that I could not even access to a kali root terminal with ALT+F2 because the screen turn off...

The
Code:
apt-get update
is the origin of the problem but I don't know which driver/lib/software is the cause of that problem...

Thank you for your help
