Buttons in Night Light menu in settings weird behaviour

[Efthimios Chaskaris]

When you press the pressed button (eg the sunset to sunrise button), it gets unpressed and nothing changes.
Then, when you press that button again, the opposite button (manual) is pressed.

Thank you for your bug report. What session do you use (Ubuntu? GNOME? xorg/wayland?)
How do you activate the night mode? What button are you talking about?

[Efthimios Chaskaris (echaskaris)]

I'm on Ubuntu 18.10 and gnome 3.30.1. The buttons are found in Settings->Devices->Displays->Night Light.

Seems like the bug you are reporting is about the settings then, reassigning

Sounds like this might be Nvidia related. See also...

I can't say those bugs are related to mine.

Fixed in Ubuntu 19.04/Gnome 3.32.1
