if you're using redshift, there is apparently a bug in the calculation. So for now, you should it use it as redshift -l 28.6100:77.2300 -t 6000:4800 -m vidmode where the first two numbers are your current locations latitude and longitude.

  I use a ~/.config/redshift.conf: [redshift] temp-day=5700 temp-night=4550 location-provider=manual [manual] lat=55.6761 lon=12.5683 and then start redshift without any arguments.

    Ahh, a couple of lat longs and Google Street View at my command.. that was a fun bit of procrastination!
    - kseistrup 13y ago
      Yes, I'm from Copenhagen and I grabbed Copenhagen's latitude and longitude from Wikipedia and rounded to 4 decimals. Perhaps I, too, should take a look in Street View… Ah, it's the Town Hall Square. :)

    actually make sure your temps are correct - take a look at this : http://jonls.dk/redshift/#comment-1013535899 http://jonls.dk/redshift/#comment-1013535899 I'm on 12.04, so I'm sure I dont have a patched redshift.

      Thanks for the link. Actually I experimented to find the ‘temperatures’ that looked the best with my monitor. Now I understand why I had to use that method.

      Oh wow, wonderful discussion :) I recently got a bit more understanding of colour spaces and colour temperature[0] and this is good reading. So how about that patents and innovation? If f.lux was somehow patented they couldn't do this, two people collaborating like this to make colour temperature adjustment even more accurate. Isn't the point of patents to protect investment in research or something? What does it say the investment if two people are perfectly willing to do this research for free :) [0] the articles on http://scratchapixel.com/lessons/3d-basic-lessons/ http://scratchapixel.com/lessons/3d-basic-lessons/ have been the clearest explanation on CIE and sRGB and where that horseshoe shape comes from and all those things. they also got a really great explanation of colour temp and black body radiation

also from the f.lux website: > f.lux is patent pending. If you make a cell phone, display, or other cool device, and want to talk about licensing f.lux?

  Patent for what? Changing temperature of screen? That will not be granted because there are plenty of prior arts.
  - TylerE 13y ago
    Such as? Doing it automatically? This is, in my book, real innovation.
    - TomaszZielinski 13y ago
      There has to be more than merely an arbitrarily defined "innovation" to grant a patent, even in the US (http://www.law.cornell.edu/uscode/text/35/part-II/chapter-10 http://www.law.cornell.edu/uscode/text/35/part-II/chapter-10).

        "Whoever invents or discovers any new and useful process"
        eli 13y ago
        You left off the rest of that sentence.
        TylerE 13y ago
        I didn't consider it relevant since it is ORed "Whoever invents or discovers any new and useful process, machine, manufacture, or composition of matter, or any new and useful improvement thereof, may obtain a patent therefor, subject to the conditions and requirements of this title."

Indeed, back when I used to develop on a Windows box I swore by f.lux. I was very disappointed when I discovered the state of their Linux version after making the switch. Redshift is definitely the best alternative.
michaelmior 13y ago
I started using Redshift when f.lux seemed not to work on my new laptop. I think I'll have to check it out again after this update though. Update: Looks like there's no new Linux version as of yet.

  There's a september 2013 update to the CLI version if that helps: http://justgetflux.com/linux.html http://justgetflux.com/linux.html

    Thanks! I missed that one.
  - Tobu 13y ago
    It's pretty crappy (no autolocation, broken option processing, still barebones functionality). Doesn't seem actively developed, and definitely not trying to do better than redshift.
    - tripzilch 13y ago
      what I think is weird is with the command line tool (xflux) that once you start it, it tells you proc ID, and if you want to change the settings, you first have to kill the other process, or otherwise you get two xfluxes fighting over the colour adjustment, causing crazy disco flickering while the new one transitions. I'd expect a tool like that to just tell the existing xflux process to change its settings. ah well, tonight I'll give redshift a try.

  Dual monitors (Lenovo L1951p and L194 on Thinkpad W510 here) seems to work fine, at least on the 24 hour preview (you have to click the sinusoidal wave).

Shame it doesn't really work so well here. It forms dark vertical stripes on the screen, making small text ugly and hard to read. Oh well, I'll just use my monitor's controls which allow lowering to 4000K.
