For me Ctrl-Alt-F1 and then Ctrl-Alt-F7 enables the screen but shows a message "This session is locked", which never goes away.
But Ctrl-Alt-F1 and then Ctrl-Alt-F8 allows to unlock normally. This is a workaround #1.

This happens on a Dell laptop (7490, built-in Intel Graphics). Maybe Dell physically disconnects the screen when lid is closed.

Workaround #2:
Default Lid Close action in xfce Power Manager is "Lock". If I change it to "Suspend", the problem goes away.
