Dear colleagues,
We have discovered an abnormal operation of the lightdm (1.30.0-0ubuntu4~20.04.1) program.
1. When no user is logged in (the initial user selection screen is displayed) the idle system goes into suspend (sleep) mode. The timeout for this event is 20 minutes.
2. I tried to cancel the entering into sleep mode. To do this, I altered the sleep-inactive-ac-timeout and sleep-inactive-battery-timeout parameters to 0.
The command sudo -H -u lightdm dbus-launch --exit-with-session gsettings list-recursively org.gnome.settings-daemon.plugins.power gives the output:
root@supercat:/home/supercat# sudo -H -u lightdm dbus-launch --exit-with-session gsettings list-recursively org.gnome.settings-daemon.plugins.power

org.gnome.settings-daemon.plugins.power time-action 120
org.gnome.settings-daemon.plugins.power use-time-for-policy true
3. I checked the result, the system still suspends (goes into sleep mode) in 20 minutes. I checked the IdleAction parameter in /etc/systemd/logind.conf, because it may affect the suspend mode. It is set to ignore.

I came to conclusion that lightdm ignores correctly given setting for not suspending the system (org.gnome.settings-daemon.plugins.power sleep-inactive-ac-timeout 0).
