Most of the people who use f.lux would not know whether they should have it start automatically when they turn their computer on. For users like you and me who don't want it to start automatically, yes, it's not convenient to do what it takes to make sure it doesn't start automatically but there is really only a handful of us in the crowd of f.lux users who don't want it to start automatically.

What's worse is, the average f.lux users wouldn't know how to get it to start automatically again due to forgetting where they found the setting. Every day on here would be a facepalm from the question being asked over and over and over, "How do I get it to start automatically again?" Or worse, "It doesn't start automatically and I don't know why" (because they are the ones who set it that way but they forgot that they did).

It's sort of the same design philosophy that Apple has. The less settings a user can change, the less likely they will create an overall experience that they hate and can't undo because they forgot how they created the overall experience they now hate.

I can tell you how to make f.lux stop starting automatically with Windows, but it requires you to delete something out of the Registry.

Escape From Tarkov is the only app that does this. Every other application disables f.lux when I use it without any issues.

In 19041 (20H1) and 19042 (20H2), you will usually see f.lux reset by the Display Settings panel in Windows. Also, occasionally a notifier will do the same. If you do not like this, you can choose f.lux options > Always use Windows internal color table to prevent it.

thanks for the report - we will take a look.

@untouchable Does f.lux show up if you quit and restart it?

@JohnCena said in f.lux doesnt launch on startup:

I have to manually open it everytime I boot my PC and its a PITA. Its set as a startup program but doesnt launch automatically and everytime I open it windows asks me to give it permission to change files on my PC.

Uninstall it, reboot, install it, reboot, and see what happens. Don’t set it as a startup program yourself because the installer does that for you.

I got the same problem with my laptop, I have 1 screen connected with hdmi and when I try to take a screenshot with greenshot its all orange.

I got the same issue, all my screenshot are orange to
anybody know how to fix this :(

UPDATE: I'm not sure that it actually did fix it, as today I tried to use the keyboard shortcut to dim the displays and only the secondary display was affected. However turning off "use internal color table" did fix the issue, so it seems just switching that setting on/off solves it.

This seems to be happening only when the second monitor is turned on later on. Because when operating system is booted with both of them already turned on then this issue does not manifest itself

Nevertheless the bug is still persistently present

That is really a new one. Can you post f.lux options > driver info?

Hi @Anakha - can you post f.lux options > driver info?
This issue is usually due to a USB-connected monitor without color controls. We are trying to make a list of all the adapters that fail.

Yes, with the free version, we always do update checks, we just give the option to install them.

In a typical year, we need to do 2-3 releases just to keep compatibility with Windows and driver updates. Some of these issues are pretty serious, and they are mostly out of our control, but we do our best to keep things working well.

Think of it this way: with many millions of users, we cannot handle telling people by hand to go update the software to the latest version - our email just does not scale like that! So if we did not do updates like this, we would have millions of broken f.lux installs and no way to fix them.

We do have a commercial version if you would prefer to receive emails about updates instead - this version never talks to the network automatically:
