Bug Description

1. Ubuntu info is listed blow:

```
Description: Ubuntu 20.04.2 LTS
Release: 20.04
```

2. the `gnome-control-center` package version is
```
gnome-control-center:
  已安装:1:3.36.5-0ubuntu1
  候选: 1:3.36.5-0ubuntu1
  版本列表:
 *** 1:3.36.5-0ubuntu1 500
        500 http://mirrors.tuna.tsinghua.edu.cn/ubuntu focal-updates/main amd64 Packages
        100 /var/lib/dpkg/status
     1:3.36.1-1ubuntu5 500
        500 http://mirrors.tuna.tsinghua.edu.cn/ubuntu focal/main amd64 Packages

```

3. I expect when the Night Light settings are set, then it should be working as specified.

4. Instead the Night Light settings only work for a few seconds, and then it went back to the original display state as if Night Light is not enabled.

This only happens when I'm booting with kernel 5.4.0-66-generic, and everything works like a charm when booting with kernel 5.4.0-65-generic.

Please help looking into this.
