When I close the laptop lid, the screen turns off, and the following appears in dmesg:
[ 5802.486819] [drm:amdgpu_atombios_dp_link_train [amdgpu]] *ERROR* displayport link status failed [ 5802.486840] [drm:amdgpu_atombios_dp_link_train [amdgpu]] *ERROR* clock recovery failed [ 5803.077555] [drm:amdgpu_atombios_dp_link_train [amdgpu]] *ERROR* displayport link status failed [ 5803.077576] [drm:amdgpu_atombios_dp_link_train [amdgpu]] *ERROR* clock recovery failed
When I open the lid, the screen stays blank. I'm running Slackware Current with a kernel built from drm-next-4.21-wip.
