With 4.4.0-53 kernel, everything is ok. I have try : - 4.4.0-59 - 4.4.0-62 - 4.8.0-36 (from linux-generic-hwe-16.04) All of us make my eDP screen flickering when it was alone. Because the amazing things is here : when my laptop is docked and get two other screen (one fullHD and one 2K), everything get back to normal. Even on my eDP 4K screen ! I don't know how to know where the problem come from. Kernel ? radeon.ko ? xorg-video-radeon ? Gnome Shell ? Is amdgpu.ko usable ? How to test it ? ... need help.
