I recently reinstalled Debian Jessie on a Pi 3. When I turn it on the screen is blank and my keyboard does not light up - before the reinstall, the GUI would only start and the keyboard would light up if I restarted it with putty.
I cannot remember how I ever managed to get it operating at that point, I think it worked magically the first time and then stopped. Now I have realized that I cannot ssh into it. I am in some trouble here as I have to present a working OpenHAB2 system to my boss by the end of the day.
Please save me.
