After upgrading to 14.04, lid suspend only worked after _removing_ those lines.
(Note: I use xscreensaver instead of light-locker, and still have to have a daemon running that calls xflock4 on lid close since otherwise it won't lock on lid close even though I have it set to do that in xfce4-power-manager-settings. Not sure if that's related.)
In my case, I had previously had these lines in my /etc/systemd/ logind. conf to make lid suspend work in 13.10:
HandleLidSwitch =ignore Inhibited= no
LidSwitchIgnore
