For Linux I suggest redshift [1]. It has been packaged for a long time and works great. [1] http://jonls.dk/redshift/

>While it supposedly exists, I could not make f.lux work. This essentially prevents me from using my computer at all at night. I'd recommend using redshift instead (http://jonls.dk/redshift/). It's free software and does basically the same thing as f.lux.

For Linux users I can highly recommend Redshift[1]. The color temperature settings seem to differ some from f.lux but everything else works great! [1] http://jonls.dk/redshift/

And don't forget redshift[0]! It needs some more open source love :) [0]: http://jonls.dk/redshift/

> I can recommend f.lux Or the oss variant redshift: http://jonls.dk/redshift/

http://jonls.dk/redshift/ http://justgetflux.com/ I started using redshift a few months ago to try and rein in my sleep schedule, but it's also done wonders for eye fatigue. Highly recommended. For those of you who aren't familiar with these utilities, they basically adjust the color temperature of your display on a schedule with the goal of reducing your exposure to bright blue light before bed. Can be toggled if you need to do work with accurate colors.

I also recommend installing f.lux (http://stereopsis.com/flux/) or redshift (http://jonls.dk/redshift/). These applications gradually shift the color temperature of your monitor to match the time of the day - the default bluish glow of a computer monitor can really mess up the melatonin production in the evenings.

There's an open-source alternative, Redshift, that does something similar: http://jonls.dk/redshift/ There's a fork of Redshfit, RedshiftGUI, which gives you a GUI if you want one: http://www.mao-yu.com/projects/redshiftgui/ I don't use either, but I've seen the former recommended, and the latter came up a few times while I was searching around to remember what its name was.

I'd recommend Redshift on Linux http://jonls.dk/redshift/

- Laptop: 13-inch Dell XPS, 4GB RAM. My original model (XPS M1330) literally went up in smoke and Dell kindly sent me an updated and upgraded version (Studio XPS 13) for free. I like the size, but it runs very hot and has some terrible design features like the air vents which are half blocked when the screen is open. Next time I'm getting a Thinkpad. - OS: Ubuntu 10.04 64-bit. Rock solid. Launcher/dock: Gnome-Do, Browser: Chrome, Editor: Vim, Version Control: Git (though my Git skills are still a bit shaky), Music: Songird. - Special mention goes to Redshift (http://jonls.dk/redshift/), which is one of those colour temperature programs. Recommend you try it or f.lux for a few days. If I turn it off at night I can barely look at the screen it's so bright. - Second OS: Windows Vista 64. This was pre-installed. I can't stand using it (not sure which of the home/business/ultimate editions it is), but I've kept it around for occasional Sky Player (for watching Premier League games - needs Silverlight), Photoshop and Portal. Other electronics: - I had a pair of Ultimate Ears Super-fi 5 Pro headphones and they were incredible: Total isolation and excellent clarity, even on the tube, but they have gone missing. I'm going to order another pair soon. - Nikon D300 Digital SLR with a few manual primes. I love the heavy, solid feel of these lenses. There's no going back to a kit zoom lens with a plastic mount after you've learned to focus quickly, which doesn't take long. My…

> I can do everything I used to have on Compiz Can you do the color manipulation a la Redshift[1]? Can you take a proper screenshot? Can you limit the size of top bars like you could in Ubuntu Unity? Most importantly, does it have the cube? [1] http://jonls.dk/redshift/

You can use redshift[1] on linux, and there are a lot of cli tools that can be used to easily script color changes in hue lights and others via cron. It's not as integrated as f.lux, but reasonably easy to get working. There's also redshift-gtk to contorl redshift from the systray. [1]: http://jonls.dk/redshift/

I used to use f.lux on Android until I found "Twilight" https://play.google.com/store/apps/details?id=com.urbandroid.lux I also used to use f.lux on Linux until i found "Redshift" http://jonls.dk/redshift/

There's also Redshift that was inspired by f.lux which may work better for some (and has a nice gtk tray client): http://jonls.dk/redshift/

I'm from Europe too. Blue(ish) is daylight colour while red(ish) is night colour. Staring at blue light hinders melatonine production, affecting the sleep cycle. Hence the existence of products like Redshift [0] and Twighlight [1]. Increasingly, this is built into visual interfaces, both my Gnome and Android have things called "night light" or something similar.

On MacOS I found serious performance issues with f.lux and now I happily use redshift[1] without ever thinking about it. 1. http://jonls.dk/redshift/

If you haven't yet, check out Redshift (http://jonls.dk/redshift/).

Thank you for making f.lux. I've been pointing friends to it for years. f.lux also inspired an open source program that I've been running on Debian. http://jonls.dk/redshift/ https://en.wikipedia.org/wiki/Redshift_(software)

Or the free alternatives f.lux inspired, Redshift[1] (for desktop) and Red Moon[2] (for Android): [1] http://jonls.dk/redshift/ [2] https://f-droid.org/en/packages/com.jmstudios.redmoon/

Redshift is one of the first things I install on Linux, and I set it pretty orange in the daytime too. It works on X and Sway; I'm not switching to Wayland until I can use it. (GNOME also has a built-in blue light filter with a manual time option [thanks to comment below]. I know KDE is working on a similar feature for Wayland but I don't know how it works.) http://jonls.dk/redshift/

> It's the worst when I'm working on my computer, due to the blue light (I've started wearing yellow sunglasses to minimize the effect) If you are on Linux you should have a look at Redshift[0]. It allows you to adjust color temperature and brightness via command line. During daytime I put more blue and brightness into the screen, depending on the weather outside (5000K-6500K, 70%-100% brightness). I do this once when I start working. When it gets dark outside I turn the values down to something like 3000K-4000K and 50%-70% brightness, depending on the amount of light inside the room. This relaxes your eyes and puts you in a better (less tensive) mood, especially at night. Redshift really became essential to me. [0]:http://jonls.dk/redshift/

Slightly off-topic, but I previously used f.lux and switched to redshift-gtk. It has a system-try indicator and auto-start built-in. http://jonls.dk/redshift/

I use a cronjob with redshift[0] and it works. You can set it to simply toggle the effect without any scheduling (`redshift -O 3400` to enable, `redshift -x` to disable). I have it set to enable at 9PM and disable the next morning when I open my laptop lid ;) [0] http://jonls.dk/redshift/

http://jonls.dk/redshift/ (If you know f.lux, it's an open source version of that)

Presently, none, but I have had a few ideas I've been wanting to get started on when I have more time for a hardware side project. The first one to come to mind is an LED lighting setup that shift's it's color temperature according to the time of day, à la f.lux[1] or Redshift[2]. LED continue to improve for general lighting purposes, but it can't be good for my sleep patterns to have daylight temp lighting in my home right up until bedtime. It would be really nifty to the lighting in my home adjust to warmer temperatures with the solar day like my computer screens do. 1. https://justgetflux.com/ 2. http://jonls.dk/redshift/

one of the most essential pieces of software in my opinion: flux: https://justgetflux.com/ and now that I've been running linux, redshift: http://jonls.dk/redshift/ I find it hard to use a computer without these now

Yes, but not all modes of redshift work across all displays. I decided to take a look at the redshift configuration[0] just now, and it seems that the newer versions have some nice config options that might fit my usecase: `gamma-day`, `gamma-night`, `brightness`, `brightness-day|night`. I should be able to setup a lower brightness with this for my really late night work. [0]: http://jonls.dk/redshift/

If one of those headless machines is running Linux, this script [1] says it will control Hue using Redshift [2]. [1] https://github.com/jonls/redshift/issues/189 (the Gist in the comment) [2] http://jonls.dk/redshift/ Edit: There's also this, which is a bit more polished: https://github.com/deuxpi/redshift-hue And this, which even has a GUI! https://github.com/poinck/lampe

What are these glasses called? Do you also know flux [0] / redshift [1] / twilight? [0] https://justgetflux.com/ [1] http://jonls.dk/redshift/ [2] https://play.google.com/store/apps/details?id=com.urbandroid.lux

I use redshift[0] on my linux machines which I really like. Cyanogenmod has LiveDisplay natively which is practically the same thing unfortunately it works off off gps location and not manually editable lang/long. Both are really helpful. [0] http://jonls.dk/redshift/
