[Bug 1777415] Re: Local authorization bypass by using suspend mode

[Jarno Suni]

Seth, what do you mean by Xfce's screenslocking package? Ubuntu Mate
18.04 does not contain light-locker package by default:
http://cdimage.ubuntu.com/ubuntu-mate/releases/18.04/release/ubuntu-
mate-18.04-desktop-amd64.manifest

What is the screenlocking package for Mate?
