I have the same problem on a fresh installed 18.10 for 32-bits, but only if
external monitor is connected.
Indeed this is a well known peoblem at internet.
sudo journalctl -b -u systemd-logind with debugging on
(systemd.log-level=debug) without external monitor shows succeeding suspend:

Nov 29 15:06:10 Gert2 systemd-logind[426]: Lid opened.
The command systemd-inhibit --list shows next entry as soon as an external
monitor is attached to the laptop.
Who: gert (UID 1000/gert, PID 2342/gsd-power)
What: handle-lid-switch
Why: Multiple displays attached
Mode: block
So program gsd-power is responsible for inhibiting the handling of the
lid-switch. The suspend-action will not occcur. This is not
configurable and I think that is ridiculous.
