I am using a docking station for my laptop. After install the 4.15.0-44 update my external monitors goes undetected after logging in or having the laptop closed.
I am on 18.04.1 LTS with Intel® HD Graphics 620 (Kaby Lake GT2) Graphics.
Going back to the 4.15.0-43 version makes it all work fine again.
