Public bug reported: When I run g-c-c and try to change the laptop's display resolution from 4K to 1920x1080, it fails silently (it should really show the error, but that's another bug). If I have run it from the console, this message appears:
(gnome-control-center:5356): display-cc-panel-WARNING **: Config not applicable: GDBus.Error:org.freedesktop.DBus.Error.InvalidArgs: Scale 2 not valid for resolution 1920x1080 I'm currently running in an X11 sesssion, but that's only because Wayland keeps crashing and the session seems to be defaulting back to X11 when I run it again.
