FVWM: Is Idle status communicated to SystemD?

Hi All,

I'm trying to get my computer to sleep when inactive. I have:

    IdleAction=suspend
    IdleActionSec=30min

in /etc/systemd/logind.conf. However, no action is taken no matter how
long the system is left idle.

After looking here:

    https://github.com/systemd/systemd/issues/1295

it looks like it's the WM's responsibility to notify SystemD of the idle
status. Does fvwm do this? (I start Fvwm from sddm, or directly via
startx from the text console.)

If anyone has it working and has any tips they can share that would be
appreciated.

Thanks in advance,

GI
