F.lux is a cross-platform program that is used for adjusting your display’s color temperature, but many users reported that F.lux is not working on their PC.

The main feature of the software is the reduction of eye strain for the user, especially when you’re on your machine at night.

As you can see, this software is incredibly useful, and in today’s article, we’ll show you some troubleshooting tips.

I’ve noticed f.lux isn’t working on later versions. It is a predecessor to built in Night Light but with a feature to turn down brightness which really is the point for me. Any solutions?

What can I do if F.lux isn’t working?

1. Update your graphics card drivers

try out DriverFix

The importance of constantly updating your drivers has been a part of many online conversations lately and it is because of all these potentially related issues.
