@herf thanks for the quick reply Herf, it seems location access for my laptop was set to "off", but I still had to update location manually in F.lux (on the bottom right) and it's working now, thanks for the help!location.PNG

@lech7 yes, it is a brightness backoff, so f.lux will not override other controllers' brightness settings.

However, f.lux will use its color settings all the time. There are some adjustments for how we map screen colors to hue colors, however.

@herf Backoff doesn't seem to be working for me at all. I'm in 4.131, I have Backoff checked, and when I use my hue app to change the color, the color changes right back to the f.lux controlled color a minute later. Pausing f.lux also doesn't pause the hue lights control.

@herf I'm having the same issue, with this driver info:

On my laptop's built-in display, the extra effects work, but not on the external monitors.

@GoldenRelik you can post "f.lux options > driver info" and maybe email us a video from your phone? (support at justgetflux.com)

hi sorry, about half the posts here are spam so we had to do the manual filter. it's mainly me - will try to keep up to date.

@fluxie can you email us your profile (ICM)? support at justgetflux.com

@fluxie it is the main download now, we are slowly rolling the update.

Once you remove it, your laptop should go back to the regular color settings.

Same here~

@herf that didn't work. I don't use usb but thunderbolt.
However, an hour ago, I updated f.lux to version 4.131 (Jan 2024) and the issue is gone! I cross my fingers.

@RVogt222 if the location is right, you should check your timezone/system clock here:

Sometimes the timezone gets set to the wrong one, and so the displayed time "looks" right but it isn't really.

@Artsem-K

this can be done by setting the "late" slider all the way to the right, or by choosing the "classic f.lux" preset. only about 10-15% of Windows machines have a light sensor... if you mean to network the smartphone so it can be used as a "nearby" light sensor? then not really, it is too difficult to do things in the background on most of them
