f.lux beta (another thread)



  • @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.

    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):

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

    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.



  • I'll just try to explain this using my copy of f.lux.

    Ok. At the time of this post, it is 12:50 PM. Considering that, let's tell f.lux that I woke up at 6am. This isn't true, but let's just pretend I did. Now, as you would expect, my light sensitivity would be extremely low right now, and that's precisely what f.lux says:

    0_1492796653936_f.lux example.png

    Check that out. Pretty much no light sensitivity, just as you would expect.

    Now, let's change my wake-up time. Let's tell f.lux I've been awake for 14 hours. Check it out:

    0_1492796764590_f.lux example 2.png

    As you would expect, being awake for about 14 hours means you're likely going to begin being very sensitive to light and you will want to think about going to bed within an hour or 2. The location of the ball is right where it should be.

    Let's do one more! Let's tell f.lux I've been awake for just over 15 hours. Check it out:

    0_1492796969235_f.lux example 3.png

    When was the last time you had been awake for 15 hours? Do you remember how you felt? Do you remember how sensitive to light you were in comparison to just 6 hours prior? Yeah, I'd say this is quite accurate. Look at how sensitive to light it says I am. It's almost maxed out! Let's max it out just for fun:

    0_1492797131798_f.lux example 4.png

    There we go. 16 hours. Carefully observe how you feel the next time you've been awake for about 16 hours.

    Can you see how this works? I can post more examples if it will help.

    As you can see, one of the goals that Mike and Lorna has is to educate us so that we can improve our quality of life. F.lux is far more than just a simple little program.



  • @herf

    Thats great! Brightness setting is really welcome! I am looking for fixed mouse cursor (broken in v4.26 - reported here in the another topic).

    Any ETA for the brightness? Maybe in v4.30? :)



  • @TwoCables Thank you for this and the post before. Really nice explanation. I'm starting to get it maybe.
    When I wrote that message, that was the time of my screenshot.
    I changed location so that it would dim my display right around now (20:00 - 21:00).
    So now (20.45) with location: 39.40N, 3.20E (Spain island vertically under Paris)
    20:45

    If I change the location to my current location 49.10N, 17.50E (Czech Republic)
    My screen dims to the Sundown color. So I think it starts around (19:00 - 21:00).
    20:45

    My problem is, I want it to start dimming my display at around 20:00 - 21:00, not before. Modifying is my earliest wake time does not help with this. I think. Do I not understand something with f.lux functionality?

  • @herf Thank you for your work! F.lux is really amazing piece of software, must have!

    I am looking for other improvements and features, keep us updating.

    P.S. Would be nice to add a link to your website for changelogs/post changelogs for every version here on forum in one thread.



  • @herf can you please explain what exactly Software mouse cursor (fixes "white cursor") does in these last builds?



  • The new build seems to have fixed my calibration issues. I'm not sure how, but thanks.



  • v4.27 - I like the new way how you redesigned the f.lux settings - much better!

    My ideas:

    • make the setting icon under the day preview easier to open - some users dont know that it is settings
    • add a link to change location to this menu (mentioned above)
    • settings for disable - I think that name of apps is not complete (only one word from the first name; should you capital letter)
    • on mouse hover (icon next to the clock) - show color temperature

    Just my ideas, sorry for my English, not my native language.



  • I think there should be a way to manually choose a program when configuring autodisable settings. Having to start the program and have it selected is kind of a pain and not always practical.
    Also, for some reason f.lux un-hides itself from the system tray at start. That's kind of annoying.

    I agree!



  • BTW shouldn't there be an option to stop f.lux from running at startup? I know the point is to integrate the program seamlessly with windows but an option would still be nice.



  • So Windows has these Notification Area Icon settings where you can change stuff on a per app basis, since flux changes path to the exe on every update (assumed) it counts as a new app for those settings and falls back to the default.
    alt text

    Can this be avoided? I suggested using Squirrel (https://github.com/Squirrel/) as an updater before, it avoids this by pointing to a stub exe which never changes path/version but if you don't want to use Squirrel, the same technique could be applied here, too.



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

    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.

    Oh this is the same problem I just reported, sorry for duping. It's because of the path of the exe changes with every update
