Bug#1020941: gnome-control-center: Night Light is unavailable on a system where it was working earlier

[Chandra Sekar Srinivasan]

Package: gnome-control-center
Version: 1:43.0-1
Severity: normal
X-Debbugs-Cc: chandru.in at gmail.com

Dear Maintainer,

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.

$ lspci | grep VGA
06:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Cezanne (rev c9)
