Bug#1009990: libmutter-11-0: Night Light is unavailable on a system where it was working earlier

[Chandra Sekar Srinivasan]

Package: libmutter-11-0
Version: 43.0-2
Followup-For: Bug #1009990
X-Debbugs-Cc: chandru.in at gmail.com

Dear Maintainer,

Even after upgrading mutter to 43.0.2, the Night Light panel under
Display settings says,

"Night Light Unavailable

This could be the result of the graphics driver being used, or the desktop being used remotely"

I have an AMD graphics card and Night Light used to work on this system
until one of the updates in the past broke it, as described in the
original report.
