Public bug reported:
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.
