Comment 2 for bug 1934409

From system settings, I can see both monitors in Display configuration.

From command prompt, I can see both displays when I use xrandr.

From command prompt, I can only see one display when I use colormgr get-devices-by-kind display

Did not have this issue with Kubuntu 20.10.

My notebook, which hasn't been upgraded from 20.10 yet (I'll hold off) does not have this issue and it does show all display devices in Display Configuration, useing xrandr from command prompt, and colormgr from command prompt.
