I have this exact same issue. If I turn off suspend on lid close in the Gnome Tweak Tool I have sometimes been able to close the lid without issues (as in, the laptop monitor turns off and the external one blinks black for a second, cursor still visible). Since a couple of days back, that stopped working as well (it worked for at least a few weeks before then). If I close my lid now, the laptop locks and my external monitor turns off. The only way to get out of the state is to open the lid, upon which I am presented by the login screen.
I am using my onboard Intel graphics (combined with bumblebee and the dedicated Nvidia card, but clearly Intel is the active one when this happens).
