[2018 MBP 15, 10.14.2, DL 5.0.1, 2 x Dell 2417 via USB- C]

Since upgrading to 10.14.2 and DL 5.0.1 I have been experiencing a strange intermittent problem.

I normally run with the MBP lid closed and 2 external displays. Sometimes when I open the lid, the builtin display stays blank. Display Settings shows 2 displays only (the external ones), it does not show the builtin display at all. Disconnecting the external displays now leaves me with a running MBP, but no display. So the only choice is a hard shutdown, which I never like doing. If I don't hard-reboot, reconnecting the external monitors usually works, in that the external monitors work again, but the internal display still remains blank.

This occurs *nearly* every time I disconnect the external monitors, regardless of whether I open the lid first or not.

Has anyone else seen anything like this behaviour?

Thanks!
