Xubuntu not automatically suspending after idle anymore

When I first installed Xubuntu on my system, it would automatically suspend after the set idle period no problem. But I seem to have changed something and its no longer working.

I’ve checked the usual suspects, first and foremost being that I have actually set it properly in xfce4-power-manager which I think I do:

When I run systemd-inhibit --list --mode=block I get the following:

WHO                 UID  USER      PID  COMM            WHAT                                                                       WHY                                      MODE
xfce4-power-manager 1000 doctor_ew 1192 xfce4-power-man handle-power-key:handle-suspend-key:handle-hibernate-key:handle-lid-switch xfce4-power-manager handles these events block
xfce4-power-manager 1000 doctor_ew 1071 xfce4-screensav idle                                                                       Inhibit requested                        block

2 inhibitors listed.

But I’m not sure if I’m supposed to be seeing that or not. Are there any other troubleshooting steps anyone can recommend, I’m not sure what else I could check at this point.

1135 ?        Sl     0:00 /usr/bin/xfce4-screensaver --no-daemon
