Screen disconnects from time to time

[kdm28]

I think we've been having the same issue. In my case, I have two Dell Monitors connected to my Dell Ubuntu 18.04 laptop through the Dell D6000 Dock. What I see happening is sometimes my monitors will go dark and say "Going into Power Save mode" as if the dock is not connected to my laptop. I then have to disconnect and reconnect the doc to my laptop. It happens a lot more often for me. It's frustrating. If anyone can help, I'd really appreciate it.
