Research direction

Start by reproducing the issue with two identical Acer monitors on Linux Mint 20.2, then trace the color manager's display enumeration and calibration path. Done means both displays appear separately and the secondary monitor can receive a calibration.

Written by the indexing model from the issue text.

Description

 * csd version - 5.0.4+uma 
 * Distribution - Mint 20.2
 * Graphics hardware - Radeon RX 580, Mesa
 * 64 bit

Issue
With a dual-display setup, the color manager only lists one display, therefore I can't apply a calibration to my secondary monitor.
I am using identical Acer monitors.

Steps to reproduce
Connect displays, boot, open color manager.

Expected behaviour
Two displays listed.
