f.lux beta discussion


  • f.lux team

    @disqQ you could probably race alt-tabbing back to the "open" f.lux window (but it auto-hides after a few seconds). We will make this easier.


  • f.lux team

    @John-Smith123 if you download again you should get one that dims less. We are trying to find the balance where people might use less extreme colors and instead dim a little more (sitting in a dark room before bed is one of these cases).


  • f.lux team

    @John-Smith123 the graph is your sensitivity to light over time, so in the morning light makes your internal clock "earlier" and at night it makes you "later". We will do some more UI to explain this, but we think it is important that we start explaining how these systems are working in the body.

    Regarding timing: there is a "more fixed" schedule in this version, but we know for certain that people are much more sensitive to light in the winter, so the seasonal component of f.lux isn't likely to go away - your body is definitely not ignoring it. But you can just set the sunset setting the same as daylight or try out the "Working Late" preset.



  • Just realize everyone that the reduced dimming (less dimming) reduces contrast at 1200K and warmer. It also reduces contrast of the color presets like Blue Sky, Emerald City, etc.

    Edit: Nevermind. I remembered that it was because I prefer to use NVIDIA Digital Vibrance in the NVIDIA Control Panel. ha! Oops. I forgot. Setting it back to 50% makes it normal again just as I remember doing with f.lux v3. :)

    I apologize for any confusion everyone!

  • @herf Tried that but didn't succeed. Anyways, glad to know it'll be easier/possible in the near future.



  • This works perfectly with the 8.1 displylink driver until a reboot, at which point instead of a 'yellowish' hue, the color turns greenish. That is until the usb monitor is unplugged, then the color on the main monitor immediately reverts back to yellow, BUT! replugging the usb monitor back in then tints both monitors green again =/

    With the 8.2 DL driver and it's regedit, the usb monitor is not affected by flux at all.

    The usb monitor in question is an AOC E1659FWUX.

    Great job folks! Keep up the good work.



  • For anyone who has a mouse cursor that isn't being colored by f.lux, let me know and I can help you. This isn't unique to the Beta f.lux for Windows, it's just Windows. That's all.


  • f.lux team

    @TwoCables oh gosh thank you for the reminder!

    @TwoCables oh gosh thank you for the reminder!

    You're welcome! It just hit me because I'm finally using the new f.lux in my unique way (800K on demand) and instantly realized this is probably the perfect opportunity to inform the majority of the f.lux for Windows users!

    By the way, the ease of being able to choose 800K whenever I want and pretty much as fast as I want is almost like a dream. This is great!



  • Hi Guys,

    Love the app.. I am on dual 27" screens. Here's my feature request that ties in with "disable for <appname>" on dual monitor setups, only have the active screen disable blue light for that app. I used it last night for VLC, but my second monitor lit up like the daytime, so while it is a great feature, it could do with multi-mon support with the disabling by app setting :)


  • f.lux team

    @Neobond thank you - this is on our list (and a big request for movie watching)!



  • In the "Custom Colors" menu at the top right corner am i supposed to have more than one entry by default? I only have "Recommended Settings" but for example, in this screenshot there's more. alt text


  • f.lux team

    @disqQ The presets synchronize from our server (they should work forever offline if they download even once). Is there anything in your system blocking f.lux from making connections? Probably we should ship a base copy.


  • f.lux team

    @disqQ Also can someone say if you are seeing a graph with "fast transitions" on upgrade from v3? We intended to default to "slow transitions" so hopefully you would have to set this. Will verify (probably will reset for everyone on next upgrade to be sure).



  • @herf said in f.lux beta discussion:

    @John-Smith123 the graph is your sensitivity to light over time

    With a double line, and lacking a vertical scale and an explanation, the graph is quite confusing. And how should this inform the choice of settings of the user?

    Other questions:

    • If I add my own preset to preset.json, will it be overwritten when they update from the server?
    • I would like to disable dimming completely, is there a configuration setting for that?


  • @herf Mine was set to fast transition on v3 and it was still set this way with the v4 beta upgrade, if this helps!

  • Great update!
    It would be great if you could set one more light point (or as many as the user wanted). For example, my PC is in front of a big window at home, so even when the sun has set down there's still plenty of light for like half an hour, in this time I find myself setting manually the f.lux to 4200K to only later let it go to 3400K.



  • @Fluxing said in f.lux beta discussion:

    It would be great if you could set one more light point (or as many as the user wanted)

    +1 it would be great to have more transition steps, even if it were only a "power user" feature exposed through a configuration file :)


  • f.lux team

    @Neobond I am pushing 4.19 which resets the pref to "slow" because that's what we meant to do. You can change it if you like.



  • [Suggestion] f.lux beta (4.18) - Change "Recommended Colors" file location

    f.lux beta (4.18)
    OS: Windows 7 64-bit.

    f.lux program files install to:
    %LOCALAPPDATA%\FluxSoftware\Flux

    The "Recommended Colors" profiles install to:
    %LOCALAPPDATA%\flux\*
    %LOCALAPPDATA%\flux\media\offer.json
    %LOCALAPPDATA%\flux\media\preset.json

    Could you install the "Recommended Colors" profiles underneath the f.lux installation folder? e.g.:
    %LOCALAPPDATA%\FluxSoftware\Flux\media\offer.json
    %LOCALAPPDATA%\FluxSoftware\Flux\media\preset.json

    ...and not even create:
    %LOCALAPPDATA%\flux\

    It just reduces the amount of clutter in the %LOCALAPPDATA% folder.


  • f.lux team

    @pizzaguy Yes I had just fixed this in 4.19, so you can delete the extra "flux" folder at the top level.



  • [Suggestion] f.lux beta (4.19) - Display color temperate along with the preset name if you select a value that currently just has a preset name displaying.

    When you adjust the sliders on the "Adjust all colors at once" page the current behavior is to display just the preset name (e.g., Daylight, Sunlight, Fluorescent...) if you happen to slide to it's corresponding value. Could you have it to where it would also show the color temperature with the preset name.

    CURRENT:
    It's daytime ----------------------o Daylight
    Sunset ------o---------------- Halogen
    Bedtime o---------------------- Candle

    PREFERED CHANGE:
    It's daytime ----------------------o 6500K (Daylight)
    Sunset ------o---------------- 3400K (Halogen)
    Bedtime o---------------------- 1900K (Candle)

    or

    It's daytime ----------------------o 6500K: Daylight
    Sunset ------o---------------- 3400K: Halogen
    Bedtime o---------------------- 1900K: Candle



  • @herf Yes, that was the problem. Firewall was blocking f.lux and now everything is fine. Thanks!



  • I've tested the f.lux LAN API with Node-RED, and it works! Now... to figure out what I want it to control...



  • Seems like there is a bug and the mouse pointer does not change temperature. This is after my having just updated to the new Windows 10 15063, so not sure what was happening before that.



  • Can you add an option to install to C:\Program Files? Binaries have no place in %appdata%, and this breaks application whitelisting.

    Previous versions could handle being moved to Program Files, but this version doesn't.



  • Is it possible to make the transitions between colors more smooth like in the previous version of flux, where you could set them to slowly occur over like an hour or two instead of being so jarring? I really liked that and miss it here, but I don't know if I just can't find the right settings options for it.

    Dimming? Or color temperature changing?

    This isn't a bug with f.lux, it's a limitation with Windows. You are probably just now noticing it because the new version is making you pay much closer attention to everything. No previous version of f.lux that I am aware of can render the mouse pointer so that it is colored too.

    To get the mouse cursor to be rendered as well (so that its color is changed), you can do one of the following 2 things:

    1. Open Windows Magnifier
    2. Make a simple change in the Registry (you will have to log out or restart Windows to see the change take effect)

    If you wish to make the change in the Registry, then open Registry Editor (regedit.exe) and nagivate to this key: HKEY_CURRENT_USER\Control Panel\Mouse

    In the right-hand pane, just double-click the sub-key named "MouseTrails" and change the value to either 99 or -1. Both should do exactly the same thing, but on rare occasions one is better than the other in some way. So if you choose and find any problems at all, then try the other and it will work better.

    Again, log out or restart Windows to see the change take effect.

    Note: when you force Windows to render the mouse cursor like this, some video games will have an invisible mouse pointer.

I really liked that and miss it here, but I don't know if I just can't find the right settings options for it.

    It was 60 minutes or 20 seconds before. Now we have 3 options: Slow, Medium and Fast.

    1. Open the f.lux menu
    2. Choose "Options (and Smart Lighting)..."
    3. Look for the drop-down menu under "How fast should transitions happen?"

    If you're referring to a very smooth transition and not one that's bumpy and glitchy, well, Michael is working on it. All 3 speeds should be butter-smooth, but it seems to me that Medium and Fast are kinda choppy.


  • f.lux team

    @kelpplankton the default now (4.19 - updating for you in the next day) should be slow always, but I missed an update case, and people who had v3 before were getting fast transitions instead. Meanwhile, you can change the speed in "Options".



  • Auto-update has never worked for me.

    Installed the beta a few days ago, just noticed today a webpage "your f.lux build is updating" had opened with Change Notes for v4.19, but my running version is still v4.18.

    I'm running Windows 10 x64 Fast Ring build (currently Version 1703 build 15063.14)



  • Why f.lux doesn´t automatically start in W10?
    The icon is in the tray but doesn´t start and i have to do it manually and that almost kills my eyes...



  • Transitions still need to be smoother, but I have a feeling you're fully aware of it and are working on it. For some reason, it's not consistent: sometimes transitions are butter-smooth and other times they can be kinda choppy. It seems the more often I make a transition happen, the choppier it becomes. I especially notice this for the feature of disabling for the current program. Going back and forth between the program f.lux is disabled for the first time or two is smooth, but then it gets worse and worse.

    Setting my location no longer lets me be quite as precise as before (which was fun). In f.lux v3, I could type numbers after the decimal and it would change as I typed. Now it seems to only allow 1 decimal. I kinda miss the extra precision. It was fun.

    I think it would be nice if I could prevent Darkroom Mode from being enabled by pressing Alt+Page Down all the way to the bottom, so to speak. It's not really a problem, but I guess it's just a preference because I'm not used to it.

    I'd like a way to make the main single-slider adjust all 3 colors at the same time.

    If I disable the wider slider range while I have any color selected that's outside the normal range of 1900K - 6500K, like let's say even 6550K or 1850K (so, even just 1 increment outside), that temperature remains selected until I touch the slider button. Of course, there's always 1 or 2 sliders on the 3-slider side of the UI that don't change when I move the main single-slider, depending on the current mode that f.lux is in.

    I think the increments for changing the color with the keyboard shortcut should be changed to 50 or 100 so that going from 800K to 6500K is possible. Right now, it can only go up to 6300K or 6550K.

    It might be nice to have an easier way to toggle between the single slider and the 3 sliders. It seems a little on the clunky side to have to go into the menu to go to the 3-sliders but then to just have convenient button to press to go back.

    I think enabling Movie Mode should force Movie Mode on no matter what. Right now, it seems it will only work fully if I have a color temperature selected that's warmer than 4400K.

    It might be nice to be able to choose how long it takes for the f.lux window to hide, similar to how we can choose how long an OSD menu stays up for in a monitor's options.

    I think I would enjoy more precision for when the sunrise or sunset will be or was, meaning I think it should also include the minutes. For example, right now on my computer, it just says "Sunset: 4 hours ago". It was actually 4 hours and 3 minutes ago, so I think it would be nice if it said that. Or like when I noticed this, it was actually 3 hours and 53 minutes ago instead of 4 hours ago. I know that simplicity is better, but still. Maybe this could be an option. I'm also referring to what we see when hovering the mouse over the Notification Area icon.

    The only things I can think of is, you still have to set your location. Or you have to configure f.lux to your preferred color temperature and also your wake-up time.

    So, the real problem is that f.lux is starting with Windows 10 for you, but it's not changing the color temperature at night. Is that right?



  • YES! thats exactly that problem! While the older version worked fine, since yesterday that i have to click in the icon and then it gets working...



  • @sitayi2308 said in f.lux beta discussion:

    When you say "the older version", do you mean f.lux v3, the one that we've had for a few years now? If so, then it would be best to uninstall f.lux, then verify that f.lux.exe is actually gone (using Task Manager), reboot, and then install the Beta fresh. You will have to reconfigure everything and reset your location, but this should make it work.



  • @TwoCables I just did that, erased everything about f.lux in the computer and fresh installed the beta versiorn, then rebooted and still the same problem. I must click in the icon to f.lux start working....

    It sounds to me like something else is overriding f.lux. Windows 10's new blue light filter? Something else?



  • @TwoCables no... could it be a bug?



  • @sitayi2308 said in f.lux beta discussion:

    @TwoCables no... could it be a bug?

    I'm not sure. You're not the only one using f.lux 4.19 in Windows 10, so I don't know.



  • I LOVE F.LUX!!! It makes my HTPC (for TV) and work PC so less abrasive.

    I did have a few features that would really help out in a home automation scenario:

    1. Simpler scheduling. I wanted to echo others comments that it is hard to get the precises schedule.
    2. Triggers Modes Manually. It would be great to be able to force the mode (daytime, sunset, bedtime) in the app from an external source (i.e. via the cmd line switch "flux.exe /mode:bedtime"). This would solve issue #1 as I could use my home automation system to control modes (it does already have a bedtime mode).


  • Just when I thought f.lux was dead and was ready to use Windows 10 Night light feature instead, a new update comes adding much more than welcome features! :)
    Here's my feedback:

    1. The option that extends the slider not only should extend it up to 9300k. but it should also extend it down to 800k.
    2. I like the color presets, but it's confusing they don't get affected by the temperature settings. For example, if I set it to Hymalayan salt lamp I wish I could make it less intense (not dimmer)? By increasing the temperature when needed. Makes sense? If I'm not wrong they are just slightly different (sometimes way different) color hues.
    3. Being able to set custom steps (including the ability to increase the number of them)/duration of the daytime/sunset/bedtime/+ phases from the UI for power users for special circumstances like the one someone brought up above. And being able to save them and then select them from the preset list in the upper right corner.
      -- 3.5. If possible make it possible to select "Reduce eye strain" or "Macular light" or any of the other filters during a particular phase. I'd love to use Macular light during daylight then have it slowly transition into the regular ember light as the next phase approaches.
    4. Being able to create custom color presets/hues from the UI! I would like sometimes to set an hypnagogic purple color reminicent of the retro color filter vaporwave videos you can find on YouTube :P (please, if that feature isn't coming soon, at least make it a preset, alongside "Emerald City" "Macular pigment" and the others!)

    EDIT: Also please let us select a dim level alongside the temperatures of any phase! I have a tasker script on android that auto dims the backlight as night time approaches. Maybe make a "dim as it gets warmer" option (I think that was an option in f.lux 3?... or was it "warm as it gets dimmer?".. hm....)


  • f.lux team

    4.20 is posted and updating.

    • some lower-impact "background" changes, with fixes (I hope) for the reported cases where the f.lux colors go away
    • Also added a "software mouse cursor" toggle in Options so you can get a non-white cursor more easily


  • @herf The software mouse cursor option works, and it's much appreciated :D



  • Just one thing: Do not overload f.lux with options! I like the usability of it as it is right now.
