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 16:56:04 Gert2 systemd-logind[438]: Lid closed Nov 29 16:56:04 Gert2 systemd-logind[438]: device-enumerator: scan all dirs Nov 29 16:56:04 Gert2 systemd-logind[438]: device-enumerator: scanning /sys/bus Nov 29 16:56:04 Gert2 systemd-logind[438]: device-enumerator: scanning /sys/class Nov 29 16:56:04 Gert2 systemd-logind[438]: Failed to open configuration file '/etc/systemd/sleep.conf': No such file or directory Nov 29 16:56:04 Gert2 systemd-logind[438]: Suspending... sudo journalctl -b -u systemd-logind with debugging on (systemd.log-level=debug) with connected external monitor shows refusing suspend: Nov 29 15:05:58 Gert2 systemd-logind[426]: Lid closed.

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. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to systemd in Ubuntu. https://bugs.launchpad.net/bugs/1799038 Title: Ubuntu 18.10 does not suspend on lid close Status in systemd package in Ubuntu: Incomplete Bug description: After an upgrade to Ubuntu 18.10 suspend to RAM due to closing the lid on notebooks does not work any more. The machine goes to suspend mode but wakes up immediately due to some events (can be network, or others). In 18.04 this issue was fixed (we had the same situation with any version since 14.04). Seems a regression. Mitigation reports suggesting to change /etc/systemd/logind.conf are WRONG. The changes do NOTHING. One might spare the time to experiment.
