Public bug reported:
Since last night's updates, I can no longer change screen resolution or
monitor alignment in gnome-control-center anymore (in gnome-shell
running under Wayland).
gnome-control-center fails silently in the GUI but reports this from the
command line:
(gnome-control-center:5887): display-cc-panel-WARNING **: Error applying
configuration: GDBus.Error:org.freedesktop.DBus.Error.UnknownMethod:
Method ApplyConfiguration is not implemented on interface
org.gnome.Mutter.DisplayConfig
All the available display modes are listed in gnome-control-center (you
just can't select them).
On the initial login, xrandr only showed two screen resolutions, one for
screen XWAYLAND0 of 3840x2160 and another for XWAYLAND1 of 1920x1080,
but after unplugging the external monitor and re-plugging it, now xrandr
shows eDP-1 with all available modes and HDMI-1 with all available modes
(you just can't select them from g-c-c).
