Describe the bug
When running gnome-control-center in order to configure my displays, I get "Could not get screen information", and am unable to access the Displays applet.

Syslog logs:
Failed to get current display configuration state: GDBus.Error:org.freedesktop.DBus.Error.NameHasNoOwner: Name "org.gnome.Mutter.DisplayConfig" does not exist

It seems like we are just missing an expected API for dbus.

To Reproduce
Steps to reproduce the behavior:
1: open a Terminal and run: gnome-control-center
2: Get error "Could not get screen information". Syslog shows:

Failed to get current display configuration state: GDBus.Error:org.freedesktop.DBus.Error.NameHasNoOwner: Name "org.gnome.Mutter.DisplayConfig" does not exist

Expected behavior
See the Display applet/section of gnome-control-center

Screenshots
If applicable, add screenshots to help explain your problem.

Desktop (please complete the following information):

 /usr/sbin/gdm --version
GDM 40.0
Rocky Linux release 8.6 (Green Obsidian)

Display panel requires org.gnome.Mutter.DisplayConfig D-Bus interface! You can try to use gnome-flashback for that.
