Whenever I try to install Kali Tools on Ubuntu 14.04 LTS. I have to reboot and it comes on but it shows a black screen (no backlight). I can open a terminal but I don't know how to use it.
These are the commands I used if it's needed.
sudo passwd root
sudo sh -c 'echo "greeter-show-manual-login=true" >> /etc/lightdm/lightdm.conf'
sudo apt-get install gnome-session-fallback
sudo apt-get install gdebi && sudo apt-get install synaptic
How do I fix this?
