SUMMARY At work, I use two external screens connected to a dock and keep the lid of my laptop closed. When I reconnect it, external screens configuration is always lost and must be set again. STEPS TO REPRODUCE 1. Connect two screens and a laptop to a dock 2. Prepare the screen configuration you like 3. Disconnect the laptop and come back later 4. Go to Step 2 and repeat OBSERVED RESULT Configuration is not saved EXPECTED RESULT Configuration should be saved. As screens are identified individually, I think that several configurations could be saved and the most appropriate one automatically selected or at least proposed.
