You can detect if a user's screensaver is active via:
gnome-screensaver-command -q
I'm trying to create a daemon to perform actions when the user is inactive, but I'm finding this command always returns false when not run from inside the user's session. For example, these variants all report the screensaver is inactive, even when it's active:
sudo gnome-screensaver-command -q
sudo -u myuser gnome-screensaver-command -q
Why is this, and how do I check the status of a user's screen from a different user like root?
command-line screen-lock screensaver

I know that it's a bit late but maybe some other people can read the answer now.
The problem is with dbus. You need to export the right variable before running the gnome-screensaver-command.
First you need to know the uid of the user. I exported also the DISPLAY of the user. You can get its value using the command w
sudo -u myuser DBUS_SESSION_BUS_ADDRESS=unix:path=/run/user/$UID_OF_MYUSER/bus DISPLAY=:0 gnome-screensaver-command --query
This worked with Debian 9 and gnome-screensaver-command 3.6.1
