Usually the brightness keys should control the backlight and not interfere, but it sounds like they are doing something else.

You can try right-clicking on the desktop and choose "Intel Graphics Settings". Look in Power and see if any of the settings there make a difference. (Personally I always turn off dpst because I don't like how it looks).

There is also a slightly newer driver for the Intel 620, not sure if that would help or not:

Sure, you can do either of these things:

turn on Options > Use wider slider ranges use alt-shift-pgdn/pgup

Did you set your wake time?

download .icc file, open color management, set as default, check "use windows calibration" in advanced settings.

also realized that v4 never applied my color profile (im using saturation in games for better colors and i can use 50% lower settings now that my color profile doesnt get reset anymore. so on win 7 v4 used to reset profile too i guess)

using v3 atm and it works. safe mode for no polling.
also whenever i launch a game flux stays active, but after i alt tab once the game blocks flux. so i can choose if i want it active in game or not. (prolly has smth to do with win 10s fullscreen. i disabled fullscreen optimizations but in win 7 every game always blocked flux while in full screen)

Does Task Manager > startup have a lot of things missing or turned off?

If anything Microsoft-related, it's probably in the "defender" or "security" logs.

@Delaney said in Today I can no longer control the brightness with control/alt+mouse scroll wheel:

@TwoCables Oh, okay version 4 for windows. Thanks. And that's interesting. I wonder why I could and now I can't. I had to click on the desktop screen to do so but I still found it easier. I'm going to miss it. Oh, and the other weird thing was I couldn't adjust my screen size on a browser with alt/scroll this morning (which I normally can) until I uninstalled f.lux. Then it worked again. This all happened right after I saw the pop up for the f.lux update but hadn't even done anything yet. Thank you though.

You have some sort of program installed that lets you do that. This isn't a feature of f.lux.

Same problem. Gets removed from task manager startup list.

Have you tried putting the flux shortcut on the "startup" folder manually?

Our installer sets things up to run with /noshow to prevent this. Do you have any software that may have removed the flag?

Reinstalling may help if so.

If you're using a Win7 server, you must have Aero activated.

Can you post f.lux options > driver info? Will let us see the versions and other things.

Also please post what it says at https://justgetflux.com/timesync.html

svchost is a wrapper for a service. f.lux doesn't use any services. The one you mention is responsible for handling network connections like Windows Update (which is now EOL'd for Windows 7).

Have you obtained the software from our website or a third party? I would try to see what it's connecting to, or run an anti-virus check.

@bikelike said in yellowish rather than redish:

Thanks for the answer. Just you don't quite understand what I mean.

When I choose soft white in f.lux, I get a nice warm tone which is mainly a shift towards yellow. No magenta seems to be added. However, this tone is not available in the color temperature range of f.lux. That is because also magenta is added. Which is similar to the Windows 10 Night Light. Do you understand what I mean now?

Personally I prefer the yellow shift over the reddish shift. That is why I like Mac better in that respect.

Ideally there would be a feature within f.lux where both temperature AND tint (as it is called in Lightroom) can be set. Please take that as a warm feature request :-)

Soft White is approximately 4500-4700K. This is still far too 'alerting' and melatonin-suppressing and circadian-rhythm-disrupting.

What precisely are you using f.lux for? Comfort? Or for avoiding melatonin suppression? If for comfort, Night Shift is ok. If for avoiding melatonin suppression, Night Shift isn't good. It doesn't matter that it looks better. Looks aren't important when you're trying to avoid melatonin suppression.

how can I get to that fallback mode?
