Previously, restarting mutter in an X11 session resulted in the previously set color temperature not being applied. Fix that by applying the color temperature right after the org.gnome.SettingsDaemon.Color proxy has been created. Furthermore, only call `update_all_gamma()` from `on_gsd_color_ready()` when the temperature has actually changed. Otherwise there is no need since the current temperature has already been (or will soon be) applied to all ready color devices. Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/3008>

/**
|
|
* MetaColorManager:
|
|
*
|
|
* Interfaces for managing color-related properties like
|
|
* color look-up tables and color spaces.
|
|
*
|
|
* Each MetaBackend has a MetaColorManager which includes interfaces for querying
|
|
* and altering the color-related properties for displays associated with that
|
|
* backend.
|
|
*
|
|
* These tasks include configuring the hardware's lookup tables (LUTs) used to
|
|
* apply or remove transfer functions (traditionally called "gamma"), set up
|
|
* color space conversions (CSCs), and for determining or setting the output
|
|
* color space and transfer function.
|
|
*
|
|
* Mutter itself does not store and manage device ICC profiles; this task is
|
|
* handled by [colord](https://www.freedesktop.org/software/colord/). Colord
|
|
* maintains a database of devices (displays, printers, etc) and color profiles,
|
|
* including the default output profile for a device. Users configure colord
|
|
* with their preferred color profile for a device via an external application
|
|
* like GNOME Control Center or the colormgr CLI.
|
|
*
|
|
* Colord defines [a specification for device and profile names](
|
|
* https://github.com/hughsie/colord/blob/1.4.5/doc/device-and-profile-naming-spec.txt)
|
|
* which is used to map Colord's devices to Mutter's #MetaMonitor.
