When I turn on my Raspberry Pi 2 with Kali Linux, the screen is still off and does not receive any signal. But if I connect with SSH, log as root/toor, startxfce4 and reboot the screen turns on with the GUI showing the Desktop.
I tried this on a Raspberry Pi 3, another SD Card and other screens but it's still doing the same thing. I need to connect first through SSH to send the signal.
I tried to use raspi-config and to modify the config.txt file but everything is still the same.
