@Vani09 it sounds like a full video driver crash. Usually our monitor info will show the video driver version, so I would look for an updated driver. Also are you on the latest version of f.lux?

@Sans96 thank you we will look into it

@T_H_M thank you - do you think it is not running on startup or is it more likely crashing? I am not seeing an uptick in crash reports on our side.

Have you found a solution?
I have exactly the same problem!
f.lux does not want to update to latest BETA.

I ended up buying another screen with normal minimum luminosity.

It's a bit unfortunate that comments take 18+ days to be validated, and that there aren't any new status since a year on that feature request.

@herf Hi! I came here to add my +1 to this feature… Even though it wouldn't figure out sunset and sunrise times, I was quite happy with having added two cron jobs that pointed to two shell scripts that pointed to two Shortcuts (quite convoluted, I know) that toggled colour filters on macOS, as a bit of a workaround for this shortcoming in f.lux, only to find out about this limitation.

I would much prefer for this to be an option in f.lux as well, as a lot of people who use it and Night Shift seem to be turning to greyscale mode as well. On the iPhone and on the iPad, they mostly use Night Shift, as sideloading f.lux hasn't been an option for years, but on the Mac, having the option to use f.lux, I reckon it would be quite popular as well. As a matter of fact, with alternative app stores and sideloading on the EU, maybe f.lux could come back to iOS and iPadOS?

@lysersz05 I noticed this the first time I installed it yesterday. Beer is making my body later, too.

@tom123 I agree. I think f.lux should behave like other apps when I have Windows set to dark mode all the time. Bothers me when random apps ignore it and blind me.

@generalKenobi thanks - the first one is 42.1 and the second is 42.2 - the untrusted certificate is quite unexpected but now appears to affect all builds from 2022 and before - must be some new security changes in macOS.

We've updated the website to point to 42.2, so builds going forward will have proper signatures.

I have created a Windhawk mod for this purpose. This mod adjusts the Windows API for f.lux in such a way that f.lux thinks the time is always same, therefore not changing the colour automatically.

@herf said in Cannot disable F.lux colors; screen tints yellow on boot up whether F.lux is running or uninstalled:

f.lux does not ever turn on the Windows 10 feature

This is not true, f.lux did turn on this feature for me, and in addition it changed the dark mode settings for my windows as well.

I de-installed f.lux because i found no way to permanently disable it in the settings, and simply pressing exit flux only worked until my computer went to sleep mode, because after waking it up, flux was on in full effect, even though it was the middle of the day.
probably something to do with my nvidia drivers, since the problem got worse after an update of said drivers.

Uninstalling was a BIG mistake!

my screen kept turning yellow (more yellow than my windows night light setting which it also turned on, don't tell me i did it by mistake because i never even touched those settings.)
i lost all control over screen colour, and now i had to re-install it, and it will keep running on my pc until i reinstall windows one day..

i love what flux is trying to do, and there are many helpful and nice settings on it.
but there is no setting to just disable it until rebooting windows which is quite essential.

the reason this tilts me so much is because i installed it to gain control, but all i did was lose it..

@SteelTalow this is a problem with Windows for a while now, and we have not gotten a fix from Microsoft yet. The decent news is that it only seems to happen once per reboot - so it's terrible but it should be just the one time.

@duke6258 Usually we ask you to post "f.lux options > driver info" so we can get a better sense of what's going on. Sometimes this is a driver issue, and sometimes it is the way that the monitors are connected.
