dmesg

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

When I open the lid, the screen stays blank. I'm running Slackware Current with
a kernel built from drm-next-4.21-wip.</pre>
