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

Output of dmesg | grep -i radeon when screen is NOT black

I have tried nomodeset . It works but causes the laptop to be slow and heat up

  • You can see this message with "dmesg | grep -i radeon". Share the output to more info – bitseater Apr 18 '16 at 14:58

My laptop is UEFI so I use rEFInd.The problem was that rEFInd was loading GRUB which caused some issues.I made rEFInd directly boot elementary OS (using EFI Stub) without GRUB and the problem went away.I could also use secure boot now
