Lets do it ourselves: F.Lux clone

taavi · 2010-12-02 14:04:11

Hi,

yesterday I encountered very nice concept of adapting color temperature by natural lightning. It modifies your monitors color temperature when day turns to night etc. Some words from original page: "F.lux fixes this: it makes the color of your computer's display adapt to the time of day, warm at night and like sunlight during the day. It's even possible that you're staying up too late because of your computer. You could use f.lux because it makes you sleep better, or you could just use it just because it makes your computer look better."

I like this idea very much, but the program is closed source and for me it doesn't work on dual-head setup.

I don't have much hacking experience in this kind of project, but can start it if someone helps with advices and maybe coding too. It can't be too difficult.

What do you think?

========================================

We have Redshift for free: http://jonls.dk/redshift/
And some GUI somewhat: http://www.webupd8.org/2010/07/redshift … -when.html

Have you tried redshiftgui in the AUR?

Superthanks z0id. It's already done!

I've been using redshift for a few weeks; I like it, it makes the screen "warmer" (but too difficult to read at night with the default setting), but I can't say it helped as far as sleep is concerned.

Well monitors should display what appears to be 6500K (A white document should be the same color as a white sheet of paper in direct sunlight). In order to alter the color temperature on the software, gamma has to be shifted towards red and green. xgamma can be used for this, however the actual amout of gamma has to be calculated based on the actual temperature of the monitor. Which I don't believe there's anyway to get that info. So one would have to offer configuration options for those who have 9300K, 7500K, 6500K, and 5500K monitors.

I wonder what F.Lux does.

I've also not noticed any benefits regarding sleep, but at least now I'm no longer killing my eyes with a bright blue/white monitor when I'm up 'til 7am. The sleeping thing is just going to have to be self-control on my part.

Anyone been able to install this lately? I tried just now and got:

Old thread, but what the heck. Color temperature doesn't affect melatonin, nor does it affect eyesight. If you want a "safer" display lower the contrast on your monitor, but this only applies to CRTs. LCDs have a fixed brightness due to the backlight. Changing the brightness setting can have a small effect.

I don't know how all that works, but I do know that my eyes don't feel nearly as strained with the red-tint as they used to.

Anikom15 · 2011-01-24 18:58:23

That's because your eyes need to do less work adjusting for the color temperature. Optimally, white on the monitor should be the same as a white sheet of paper in sunlight.

Been using redshift for nearly 2 months now and every time when I instantly turn it off at night, it comes as surprise how much nicer it is with warmer colors in nighttime. And that shift happens around 16 o'clock this time of year.

nXqd · 2011-02-06 07:13:58

I'm using xflux commandline version and it is good

TheAmigo · 2011-02-09 04:30:39

Since I can't adjust my backlight, I was hoping this would solve my problem.

Alas, neither work

redshiftgui: Failure while downloading RedshiftGUI-0.2.1-Linux-x86_64.tar.gz
xflux: This will only work if you're running X on console.

I'm guessing that xflux assumes that :0 is the only console display. I run qingy which breaks that assumption... my display is :1 (or :2, :3, etc.).

xflux doesn't appear to be open source, so that's a dead-end.

redshiftgui is, but the AUR package doesn't build it from source, it just downloads the binary.... I'll take a quick look and see if it's easy to make a 64-bit build.

You don't need redshiftgui, which only triggers console version of redshift: community/redshift ... I have 64-bit system and both installed though.

TheAmigo · 2011-02-09 23:55:02

Well, that makes things a lot easier

unexist · 2011-02-10 00:01:41

Btw: Is it just me or does xflux only work on one screen? When you use it with two or more screens it only updates the colors of the first one.

taavi · 2011-02-10 05:52:16

I've read that it's was one of the main reasons behind the need to develop redshift. And it was my main reason to search something else.

Ah cool, working now. Thanks.
