Unrecoverable failure in required component org.gnome.Shell.desktop

[stepheny]

I am running a brand new install of Ubuntu 18.10 under Wayland (but the same error occurs under Xorg) on a brand new laptop. I use about 15 Gnome extensions. In my logs I get the "important" warning

Unrecoverable failure in required component org.gnome.Shell.desktop

I have nailed the error down to this line in syslog:

failed to connect to device: Failed to connect to missing device /org/freedesktop/ColorManager/devices/xrandr_AU_Optronics_gdm_123

What is this error referring to? I have no symptoms or problems with the setup other than this error message.

That error (harmless) point to 'color manager'

Looks like related to the video devive (screen) and its pixel depth definition.

here is the main documentation page: https://help.ubuntu.com/stable/ubuntu-help/color.html

Please run

colormgr get-devices-by-kind display
from a terminal and post the output. Thanks.

Thanks for the response. I followed the instructions you linked to to calibrate the screen but the "calibrate" button is grayed out.

Here is the output of "colormgr get-devices-by-kind display"
