screen doesn't lock anymore when lid closed

[scar]

I just upgraded stable -> testing and now my screen doesn't lock anymore when I 
close the laptop lid.  I already (still) have HandleLidSwitch=lock in 
/etc/systemd/logind.conf but it seems to be ignored now.  Is it a Gnome issue?  
super+L still locks the screen.  Anything else i can check?  Thanks
