dmesg after delayed recovery from display sleep
I just got a Sapphire R9 Fury X and am testing out the new amdgpu driver with
linux 4.3.0. I am having trouble recovering from the display sleeping on
Antergos with GNOME desktop. I have tried lightdm and am currently using gdm
and seem to have the same issue. Sometimes I can get the screen back after
waiting and sometimes I just have to restart with the physical buttons on my
computer. The num lock and caps lock are responding and my monitor seems to
wake for a moment but nothing appears on the screen and it goes back to sleep.
