When there is no layout mode set in a logical monitor config, we currently just assume the configuration matches the mode that the system expects. This blows up when the layout mode expected by the system changes (eg. by turning on "scale-monitor-framebuffers" in mutter): Suddenly configs fail the validation check and get thrown away. Since we now can add one configuration for each layout mode to the config store, we can do better here: Let's only add configurations to the store where we verified beforehand that the monitor layout is compatible with that mode, either because we set it ourselves using the <layout_mode> key, or by detecting which modes the layout is compatible with. Also update monitor config ifiles to adjust for the new layout_mode, as they all are assumed to be "logical". Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/3596> |

Mutter
Mutter is a Wayland display server and X11 window manager and compositor library.
When used as a Wayland display server, it runs on top of KMS and libinput. It implements the compositor side of the Wayland core protocol as well as various protocol extensions. It also has functionality related to running X11 applications using Xwayland.
When used on top of Xorg it acts as a X11 window manager and compositing manager.
It contains functionality related to, among other things, window management, window compositing, focus tracking, workspace management, keybindings and monitor configuration.
Internally it uses a fork of Cogl, a hardware acceleration abstraction library used to simplify usage of OpenGL pipelines, as well as a fork of Clutter, a scene graph and user interface toolkit.
Mutter is used by, for example, GNOME Shell, the GNOME core user interface, and by Gala, elementary OS's window manager. It can also be run standalone, using the command "mutter", but just running plain mutter is only intended for debugging purposes.
