I am using Ubuntu on my Hp M6 Envy laptop.
I closed my lid to move with my laptop and by the time (10 mins) i opened it the screen was totally blank not black , blank. I restarted many times with no results. Got home and connected the laptop to my tv via hdmi and it works fine. What could be the problem here? Over the past months i know ubuntu has been known to crash my laptop after suspending.
