f.lux beta (another thread)



  • @herf Ah it's unclear that it means that,

    Edit:
    Ah Now I understand, I think perhaps the UI could be a bit clearer in alerting a user it won't necessarily store their precise location so they don't get confused when they go back in next time and see something different to what they entered.



  • Please add brightness to the color settings.

    Could use a disable/set color/brightness per app. (this would be amazing!)



  • Bug: The task tray icon forces itself back to being "shown" after each PC reboot. I like to keep my taskbar minimal and clean, so this is making me have to drag it back up to the hidden tray every time I start Windows. (Windows 10)



  • Bug report: "The sun is up. Light is making your body later". I also suggest to rephrase this to similar: "light is making you wake later". Also, the slider is showing the position of the daytime color selection, so not sure what it should show there--maybe the current color, updating every 20 minutes?

  • f.lux team

    @phrontisteries yes we have brightness schedules in our internal build, but it is complex enough that we have not shipped it yet.

    Actually, a couple years ago, I had my screen on a "forced" schedule, so f.lux was controlling the dimmer exactly. This was pretty good, but occasionally very frustrating, because when it was wrong, it was awful.

    Since then, we've tried to listen to the keyboard keys that adjust brightness, so you can override our "forced" schedule. This almost works, but there is enough 'noise' in the system (power changes, ambient light sensors, etc.) that it wasn't ready for prime time yet.

    That said, I really wanted to get it done for this version, so it is still on my list for the next one.


  • f.lux team

    @Tungsten_smooth yes we have more to do here. Wake time corresponds somewhat to circadian time, but not exactly - it is also related to sleep debt and the ability of the body to stay asleep (which varies by age). So if you talk to elderly people who have trouble sleeping through the night, they often need a stronger "amplitude" signal (more light during the day) and not always a "phase shift" in schedule (as do 20 year old students who have to get up early for class).

    For f.lux right now, it is a very important time to show "how your body is reacting". This next chapter is "how to help your body do what you want it to" and I hope that can be simple too.

    In the UI, the big slider should usually reflect the current-nearest preset, which is not the best way to do it, but better than having an infinite number of control points that are hard to delete! We could do this better but it makes sense at most times of day.



  • I'm on 4.21 and it doesn't play nice with Windows 10 (toast) notifications. As there is no option in the program's menus, I switch off the sound or even the notification altogether in WIndows Settings (screenshot attached), but after a system restart, f.lux resets the notifications, creating a new entry in the notifications app list.
    Screenshot of windows notification options
    As if f.lux is registering a new instance with the notification system each time. Kind of annoying. I'd love in-program options or a fix for playing nice with Windows system.

    Otherwise I love what you did with per-app options. Been waiting for it for ages.



  • I have both f.lux 4.21 on my Windows PC and f.lux 39.94 on my MacBook Air next to each other.
    The location is the same and on Windows I have set the transition time to "slow" and on the Mac I have disabled the "fast transitions" option.

    Unfortunately their timing is not the same. :cry:
    f.lux 4.21 on Windows is already at 1900K while Mac with 39.94 is still at 27xxK and still going down.

    Can you please align the transition times across these platforms? Bonus points if the Android app also does exactly the same. :)


  • f.lux team

    @hsiktas well they are using the same code, finally. Things to check:

    1. same wake time
    2. same location
    3. same presets
    4. https://justgetflux.com/timesync.html looks similar?

    It turns out my Mac and PC are about 8 kelvin apart (testing during the fastest portion of the bedtime transition), but they are also about 7 seconds apart too.

    The next update may shift the wake timing a bit, so there might be some skew until we update the Mac. But right at this minute for you, they should be the same.



  • @herf
    I had indeed different wake times on both machines and I just adjusted them. This seems to solve my problem. :)


  • f.lux team

    Pushing 4.25 via auto-update, to get everyone testing the newer code. I definitely have bugs filed for all the things in this thread too!

    Thanks everyone.


  • f.lux team

    @hsiktas and I just shifted the wake transition earlier so "fast transition" people should not wake up to an orange screen. However, at night the Mac and PC should still be the same. Glad to hear you got it. :)



  • I'm not sure if I'm too early, but it's not automatically updating for me. I have 4.24.



  • @herf Hey I just installed 4.25, thanks for support DisplayLink Monitors! That was a deal breaker for me! (I still used Flux but the DL monitor had a custom color setting to match my primary monitor at 2900K)

    Bugs
    Only one I found so far: when prompted for UAC in Windows 10 v1607 build 14393.1066) ,flux will instantly show the blue colors on both displays as long as the UAC prompt is up.

    This also happens at the lockscreen. So there is a little bit of inconsistency when working at night as my lockscreen is at 6500K and when I am prompted for UAC for opening programs or scripts that require Admin rights



  • @herf With the new release I just had installed, I very clearly see the future for this program and your other projects: You and Lorna (and probably other people working with color controlled lights) want to make it abundantly clear to avoid or reduce light after / near sunset as much as possible. The "vignette" mode really makes this obvious!

    I do appreciate your specific example, and I'm still in school, but I don't have to get up early for that, it's for other reasons and it's not mandatory. I remember you talked about a phase shift versus a stronger light / dark cycle and I'd a bit of education about what you're describing. My understanding of this topic only involves regulating light / dark timing, so bright light during the day, etc. So, what is a phase shift?

    Thank you, it's great to see you both on the forums, it does seem you've got a bit more free time not working as much on the beta now that you've got it working. You and Lorna are very helpful and it's just incredible how much you all can help explain some of information about light and sleep, and we keep learning more (and I'm sure your research is non-stop so far). I am just in awe of how much there is to learn about all this, I never thought I'd learn so much about what seemed a very simple topic.



  • I did a Performance Test (just noticed the button there) and I got 64 - 70% dropped frames at 60FPS. Is that normal? Feels like a lot. Would you recommend disabling f.lux during gaming then?



  • How are you guys getting 4.25? It's not automatically updating for me.

    Same here. This beta has opened my eyes to one simple fact: this is an extremely deep rabbit hole.



  • @TwoCables said in f.lux beta (another thread for 4.21):

    How are you guys getting 4.25? It's not automatically updating for me.

    It auto updated here without any problem. I just quitted f.lux and launched it again.

    Btw, one bug, that was already present in build 4.24 at least, can't tell about the previous ones. When the screen goes to "sleep mode" aka AFK, when i return to PC and the monitor powers back on, f.lux has daytime temperature. I am forced to click on f.lux icon in the taskbar to bring it to foreground in order to get back the right temperature.


  • f.lux team

    @caydenly this is a common result now, since GPUs are synchronizing with the backlight. In this version, we have done a lot of optimization to send as few commands as possible, because dropped frames at 60hz are hard to avoid now. (Before the power saving efforts of the past couple years, this stuff was totally free and never dropped frames ever.)

    Also, for gaming, you can use our "very fast" transition setting, so the number of times we will touch the GPU is low.

    Yeah, I exited f.lux 4.24 several times. I right-click the icon and choose "Exit f.lux".


  • f.lux team

    @Tungsten_smooth Well, we don't know the answers yet -- in particular a lot of people need better ("more") light exposure during the day (which involves screens too, because we work in offices that are too dark to accommodate them). The first part of our job with f.lux is to think up hypotheses and motivate people to test them. The vignette feature is based on some recent research, and I'll write down the idea sometime soon.

    But the main work we're doing is to make models and test them in the real world (not just have people believe they're all true).

    Regarding your question about phase vs amplitude:

    Phase

    Most people think of the circadian system ONLY in terms of phase - e.g., we would call a night owl "phase delayed" and an early bird "phase advanced". This means that their internal clock is offset from the solar time by a certain amount.

    So when you are a night owl who wants to wake up earlier, you want to "advance" your system by seeing more light in the morning and less at night. And the reverse for an early bird who wants to sleep in. As such, a lot of our users tend to be night owls. But you might think this is the end of the road for circadian topics - is your phase aligned with how you want it to be?

    Amplitude

    What is clear from experiments on shift workers and the elderly (and many rodent models) is that the overall circadian rhythm in the body can be suppressed. In some cases, it's operating at a lower "amplitude" because light and dark are not clearly defined or not happening at the right times. For instance, people who spend time in natural lighting during the winter have an enormous melatonin amplitude thorughout the night (you can see melatonin in the blood lasting 14 hours), whereas most of us in the modern world are living in a "perpetual summer" and we have a relatively small melatonin duration in comparison to natural conditions.

    We think some sleep problems (and some immunity and seasonal effects) depend to some degree on the "strength" of the circadian rhythm, not just whether it's phase aligned. (Of course, a misaligned rhythm, e.g., in shift work, will almost always have a reduced amplitude, so they are somewhat related.)

    Also, not all sleep trouble is circadian, so when we can, we look for ways to help people get to bed on time. It is probably true that we could do a lot of good here that's completely unrelated to magic science and more to human behavior.

    @TwoCables Rabbit hole is exactly the way we talk about this - once you fall in, you realize there isn't a bottom. But first you have to fall in....



  • @herf
    Hi ,
    just installed the new "beta" version ..initially it's a bit confusing.. but I think I have my "old" settings back. My Anti-virus did not like the installer ? I agreed /approved that the file was legit but that is something you might need to work on, overall I tend not use the settings at all once the program is installed .. "set and forget " is my motto.

    suggestions ,

    • see if you can get back to the old UI .. the waves on the screen make it very confusing , something compact and neat ?
    • I dunno what they are , the line " light is making your body earlier. means a big huh to me ?
    • change waking time to working time .. ( unless we have people that roll out of bed while working)
    • no help ? not even a link or a help file ? ( maybe could explain how it works and the settings )

    aside from that its good, I have pointed several people to this who work late in the night and most of them give raving reviews ..



  • Wow. Great job with the new software mouse cursor! No reboot required! Now we no longer need to use any tricks.



  • I don't know if this was just a one-off glitch, but I was taking the color temperature down and up with the hotkeys and somehow got it into a situation where it just wouldn't stop going up. It was at somewhere like 70,000K before I ended the f.lux process and restarted it (when I restarted, it was at something like 18,000, which was more manageable to get back down to where it was, especially since it wasn't going up anymore). I've noticed there's an 800 lower bound, but is there an upper bound when using the hotkeys?


  • f.lux team

    @citrusella It goes up to 100,000K, which isn't so enormous - a blue sky can be 50,000K. What we mainly need is a more non-linear adjustment up there, because nobody needs tiny increments all the way up to 100,000K.



  • 4.21 worked flawlessly (notebook, external monitor via vga, win10, integrated graphics).
    4.25 now has the following bugs:
    -Checked “Use Monitor Data for Calibration” makes external monitor greenish. Unchecked returns colors to normal.
    -f.lux colors don't appear after the monitor comes back from power saving standby. Have to click the f.lux icon in order that they come back.


  • f.lux team

    @AlbertBaer Thanks for the note on the monitor...will think about how to make it so we can debug the settings.

    Regarding standby: which OS version and GPU are you using? And 4.21 did not have the trouble?



  • @herf Yes. I'm back to 4.21 now and f.lux colors are right there when monitor comes back from power saving standby. It's latest Win10 creators update 64bit Pro. And GPU is ancient GM45 ;-).



  • Yea, i'm having the same problem, as i reported here yesterday: https://forum.justgetflux.com/post/13522



  • What exactly Software mouse cursor (fixes "white cursor") does in this new build? I see it's not using MouseTrails in the Registry.

    I know you're looking for an answer from Mike or Lorna, but it looks to me like it's doing the same thing that the Windows Magnifier is doing.



  • @TwoCables Hmm, but the Magnifier process is also not running. But yes, probably isn't something new.

  • Great! No "coming back from slumber" issue and "greenish color" issue any more on my external monitor with 4.26.



  • The software mouse cursor isn't working for me in 4.26. I went back to 4.25 for now so that I don't have to worry about it until you can check it out.

  • (version 4.26)

    Hi

    Nice to see Philips Hue integration working again!

    Unfortunately, with the current features it is quite unusable for me. Here are some of my issues:

    It controls all lights in the setup, I can not specify individual lights. I only want to control the light behind my screen.

    Brightness is always set to maximum. I would like to set the brightness myself. It is too bright in the evening.

    I can not set the max. color temperature.

    I'm aware, that the Hue integration has no priority, still, it would be very nice to have more options!

    Thanks for your work!



  • (version 4.26)

    Hi, nice changelog. Tried the Vignette mode but on multiple monitors, the white spot is in between of the two.
    Would be great to choose the weight of Vignette (radius and effect)

    Another thing, even I think the interface is not user-friendly. There is more options now, that is great but I'm missing for example the settings button. Now I have to right click and choose the third from top.
    I would rather see: 1st - Open F.Lux, 2nd - Settings, Next-to-least - About., Least - Exit F.Lux
    And move Change location to Settings. Or to main window as button. This is option that is set once and forgotten. It should be somewhere where it is not in the way for other things.

    Disable for... does not work when I have open F.Lux window. When I minimize it, click on Sublime Text, right click on F.Lux task icon, there is Disable for Sublime Text and Disable for Chrome. But when I'm focusing Chrome, Disable for only shows Chrome, not Sublime Text. Weird :-)

    I find it kind of disrupting that when I have opened F.Lux window and I lose focus (click on Chrome / Away for a second) it will minimalize itself in like 5 seconds... Please disable this. Or make it an option in settings

    When mouse is pointing on the waves diagram, it would be cool to show vertical bar with time stamp so I would see the time. Reason: I set a random location somewhere thousands of kilometers from my location to "pinpoint" settings when it will go down. But I don't see anywhere the exact time. Just guessing.

    And the last one: Is it really so problematic to add to the main window User-setting of time?

    • Daytime: 6AM, Temp: ...
    • Sunset: 21PM, Temp: ...
    • Bedtime: 23PM, Temp: ...
    • Transition: Immediate | X minutes

    (Just like you have it in the Adjust all colors at once but with those time settings on the left of the movable bar.)

    Everyone would be happy in my opinion. I understand you had a LOT of work with the location system. But give users the availability to change it to user-specific times. Some people go to be at 8PM, some at 2AM. Night owls.

    Anyway, great improvement. Those are only my points. I love your program. So I would love it to be even better :-D


  • f.lux team

    @little-nemo thanks - these things are on our list... and we even have the brightness parameters internally (just no UI for them yet). Hopefully soon (but probably not this version).



  • The reason why Chrome shows when you do that is, it's giving you the option of also disabling f.lux for Chrome in addition to your other program. If you want to undo disabling for a program, then just make that program the last thing in focus before you go to f.lux.

    You don't need to see the exact time. The ball that's on the curves shows you where you are and what your light sensitivity likely is. It is based entirely on your set wake-up time. So, it's best to just focus on where the ball says you are in your likely light sensitivity based on your wake-up time.

    If you don't want to tell f.lux when you will be waking up, then tell it when you woke up by simply choosing the time that you got out of bed that day. Simple. :) That way, you'll always be able to look at the ball to see what your most likely light sensitivity is. Adjust your "wake time" and you'll see. Keep doing it and keep studying where the ball ends up. Before long, you will know how to read it.



  • @TwoCables I know how to enable/disable. I was just wondering why after focusing Chrome there is only Chrome and after focusing Sublime there is Chrome and Sublime. But maybe I was just quick and there is some time limit like 10s or sth like that.

    Time: Ok so... If I print screen my f.lux setting, when exactly will my screen begin to dim? MyFluxLocSettings



  • Hi.
    Currently I am using beta 4.26 version. I have a question and suggestion.
    How to change the color changing time schedule (like the newly added 'Adjust all color at once')?
    If it's not available in the application, then is it possible to add this feature. because its always change the color automatically, but I want to set the timing manually. I have found that there is only one time change option available but I want Daytime, Sunset and Bed time change slider at the same time manually. Hope you understand my point.
    Thanks
    Hassan.

    I just told you why. It's doing that so that you can disable Chrome in addition to that other program (multiple programs instead of only 1 at a time). I was not trying to tell you how to disable and enable.

    I can't tell you when your color temperature will change because I don't know what time you took that screenshot at. I don't know what time zone your in. So again, continually play with your wake time setting and you will soon get a feel for what you are looking at.

    Is your sunset really in 1 hour? It doesn't matter. What matters is, does that ball really represent where you are in terms of your most likely sensitivity to light? Do you feel that you've been awake long enough that you will want to go to bed in maybe 3-4 hours? Judging from where you are on the curve, you should be thinking about going to bed in a few hours.



  • Hello.
    I use DisplayCAL to calibrate my monitor. Since the 4.22 update where you added "Use Monitor Data", f.lux resets my calibration when I open it no matter what time of day it is and whether or not the "Use Monitor Data" setting is checked. Is there any way for me to fix this? So far I've been forced to return to f.lux 4.21 in order to keep my calibration in tact.



  • @TwoCables It looks like they might have taken the screenshot in proximity of 7:45 pm? (Not sure that helps, but...)



  • @citrusella said in f.lux beta (another thread):

    I see why you think that. Nevermind. I had a much worse post than this, so yeah this post isn't the original version.

    It says they've been awake for 12 hours. However, they said they manipulate the time zone quite a bit.

    So, yeah, I know what I'm looking at here, but considering how unique their usage of f.lux is, I can't go by that screenshot.
