GDM gsettings overrides and monitor.xml

Do these really apply to Gnome 3.30 and newer? I find that my scale setting does not take effect any longer even when monitors.xml is identical to my desktop. And I found that logging into my desktop with either Xorg or Wayland did not generate a different monitors.xml. Also, when I attempt to run various tasks that try to apply gsettings to the gdm user:

$ machinectl shell gdm@
Connected to the local host. Press ^] three times within 1s to exit session.
/sbin/nologin: invalid option -- 'l'
Try 'nologin --help' for more information.
Connection to the local host terminated.

And attempting to apply a gsettings change with sudo:

$ sudo -u gdm dbus-launch gsettings set org.gnome.settings-daemon.plugins.power sleep-inactive-ac-type 'nothing'
[sudo] password for chris:

Is this no longer the correct way to disable suspend for GDM? I also notice it only seems to autosuspend if I disable Wayland, and it does it instantly on logout, not after a timeout. - Kode54 (talk) 01:19, 7 January 2019 (UTC)
