Bug#893361: gnome-color-manager: Color profile is applied to wrong display

[Mladen Mijatov]

Package: gnome-color-manager
Version: 3.28.0-1
Severity: normal

Dear Maintainer,

If a display is connected to DisplayPort, color profile for laptop screen is
applied to external display. Any color profile changes are always applied to
external display.

My configuration is the following:

- First display (Lenovo ThinkPad MaxBright Display)
- Second display through DisplayPort (Dell U2414H Monitor)

>From color settings page changing color profile for first display changes
colors on second display. Also, changing color profile on second display also
changes colors on second display.

As laptop has only one DisplayPort and doens't support daisy-chaining I am
unable to test for more than two displays.
