Just as gsd-color does, generate color profiles. This can either be done from EFI, if available and the color device is associated with a built in panel, or from the EDID. If no source for a profile is found, none is created. The ICC profiles are also stored on disk so that they can be read by e.g. colord. The on disk stored profiles will only be used for storing, not reading the profiles, as the autogenerated ones will no matter what always be loaded to verify the on disk profiles are up to date. If a on disk profile is not, it will be replaced. This is so that fixes or improvements to the profile generation will be made available despite having run an older version earlier. After generating, add some metadata about the generated file itself needed by colord, i.e. file MD5 checksum and the file path. Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/2164>
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.

Git messages
Commit messages should follow the GNOME commit message
guidelines. We require an URL
to either an issue or a merge request in each commit. Try to always prefix
commit subjects with a relevant topic, such as compositor:
or
clutter/actor:
, and it's always better to write too much in the commit
message body than too little.
Default branch
The default development branch is main
. If you still have a local
checkout under the old name, use:
git checkout master
git branch -m master main
git fetch
git branch --unset-upstream
git branch -u origin/main
git symbolic-ref refs/remotes/origin/HEAD refs/remotes/origin/main
