How can I configure my Ubuntu 14.04, logging in using Gnome 3, to lock the screen when I close my laptop lid?
All Settings ► Power only offers
Do nothing or
Suspend as options when I close the lid.
All Settings ► Brightness & Lock is configured with Lock ON, Lock screen after Screen turns off. It doesn't seem to work.
I've tried editing
/etc/systemd/logind.conf to set
HandleLidSwitch=lock and rebooting; nothing changed.
