Laptop lid, when closed, don't suspend even if lid-close-suspend-with-external-monitor=true

[Cyrille37]

Hi
I've just installed Ubuntu 24.04.3 LTS on a Clevo NS5AU.

I've change the dconf value /org/gnome/settings-daemon/plugins/power/lid-close-suspend-with-external-monitor to true but closing the laptop while a external monitor is present does not suspend the system, the external monitor becomes the primary display.

Also, the systemd-logind has not this option.

Regards & cheers.
