Half of the time when I turn on my laptop I get a black screen.CTRL+ALT+F1 also shows a black screen.I have to put my laptop to sleep and back on to get the screen to work.When my screen is not black I see a message before boot for about a second relating to the radeon driver and then it boots correctly
I am running default drivers with kernel 4.4 installed. The laptop is a HP Pavilion g7 2269wm
