gsd-power is not using lid-close-suspend-with-external-monitor value

[Karol Pucyński]

I'm using 18.10 on Lenovo T480. Suspending on lid close is not possible with external monitor attached.
Even if everything is set properly:
$ gsettings get org.gnome.settings-daemon.plugins.power lid-close-suspend-with-external-monitor
true
$ dconf read /org/gnome/settings-daemon/plugins/power/lid-close-suspend-with-external-monitor
true

gsp-power is still blocking system suspend:
$ systemd-inhibit --list --mode=block
     Who: kpucynski (UID 1000/kpucynski, PID 1956/gsd-power)
    What: handle-lid-switch
     Why: Multiple displays attached
    Mode: block

Even with LidSwitchIgnoreInhibited=yes set systemd-logind is not ignoring it:

$ grep -v ^# /etc/systemd/logind.conf

HandleSuspendKey=suspend
HandleHibernateKey=suspend
HandleLidSwitch=suspend
HandleLidSwitchExternalPower=suspend
HandleLidSwitchDocked=suspend
SuspendKeyIgnoreInhibited=no
LidSwitchIgnoreInhibited=yes

$ journalctl -f -u systemd-logind

Thank you for your bug report, the key is ubuntu specific and buggy, but the feature request is also discussion upstream on https://gitlab.gnome.org/GNOME/gnome-settings-daemon/issues/111
