Hello when i open my kali before i get the login page i get just one black screen with and underscore left top when i click Ctrl+F1 i can login but i am still in the blackscreen i tried apt-get update and internet seems to work i also did apt-get upgrade but something happens and it took too much time after finish i still have the underscore. all this happens because i installed some drivers of card graphic (ati mobility radeon hd 8670m) before install these drivers the blackscreen happent only sometimes. (Sorry for bad english)
