Hi
when it’s evening, the colour in Firefox but also a part of the desktop changes to a darker white.
It’s not changing the Theme of Firefox, I always found searching. It’s this nigh-mode, that helps you sleep in easier.
How do I turn in off in the latest NomadBSD with original Openbox?
Thanks
[This is a non-answer]
Yes, this behaviour is so subtle, that I only notice it, if I sit in front of the screen at the exact moment it happens…
But I would like to tweak it - not turn it off, so I will follow this subject 
No time to examine this path right now…
No it makes it unusuable. It is not subtle.
I changed to a Radeon R7 240 and still. Onboard Intel the same. It is not the card.
No, it is software - not hardware
Have a look at this thread (now you know the “service” name, but it’s not your specific problem):
sudo pkg remove redshift
And the problem is literally gone
Thanks for the help!
