Bug#971063: systemsettings > display/monitor window is empty

[tom <forensic@milwpc.com>]

Package: systemsettings
Version: 4:5.14.5-1.1
Severity: normal

Dear Maintainer,

I ran systemsettings5 > hardware > display and monitors; and
the righthand pane: "configure monitors and displays"
is empty except for the blue dot with an 'i', which
does nothing.

Below are the messages/errors: 

rex@debian11:~$ systemsettings5

I realize the transition to wayland is fraught with pitfalls, 
extra work for everyone, and just one big PITA. But the open-source/Linux 
community really needs to correct a number of issues with X. I don't think 
it will be as difficult as some have imagined. 

The unwillingness of certain maintainers to update their packages
for wayland appears to be contagious in a "Then I don't have to 
either!" sort of way, and everyone jumping on the gnome developers 
for defaulting to wayland.

I know there will be problems, even with 'stable'. Don't worry!
It's very frustrating for developers when documentation is incorrect,
incomplete and/or nonexistent. 

We can each do our part to figure this thing out.
