I've installed the ubuntu version into my kubuntu. After launching it does nothing. Which isn't strange because the /usr/bin/xflux is a 32-bit binary and the package didn't request the required libraries. I have to consider it doesn't support 64-bit linux. Come on. Linux is not Windows. Everybody and their dog already run 64-bit version. It makes no sense not to. All the software is built for 64-bit too. It's just a…

I'm not sure what you mean by "Linux is not Windows" in this context. In my experience, most installs of Windows these days (Windows 7 and Windows 8) are 64-bit installs. That's what is sold at Best Buy on their desktops and laptops for example. On the contrary, when a user goes to install Ubuntu, they're recommended to use 32-bit. When I'm on forums, people mention compatibility problems with 64-bit Linux and recomm…

Do you remember Firefox trying to cancel 64-bit build for Windows? Stating they have a lot of extra bugs in it?

In Windows they still run 32-bit software on 64-bit OS, but a typical Linux install will have not a single 32-bit program.

That's why not having a 64-bit version is pathetic.

I happened to start using f.lux on my macbook 3 days ago, and I'm loving it. Where I am (south west England) sunset is around 4pm, and I usually work until 5 or 6pm. Having a much warmer screen tone as the sky gets darker really feels nicer on my eyes.

I think you really have to use the slow transition (1 hour) mode, 20 seconds is quite jarring.

I program in Aptana with coloured text on back background, and I don't find it any harder to read in night mode. Overall, I can't recommend f.lux enough.

On a related note I've just started using http://www.protectyourvision.org to remind me to get up and move around every 20 minutes, also a highly recommended tool.

I use xflux on a 64-bit Debian system and it works. I'm not sure, but you might have to specify the location parameters when starting it.

I love f.lux. It does take a bit of getting used to, but if you wait it out, you'll enjoy it. And, the research they've done on light is quite impressive too: http://stereopsis.com/flux/research.html That being said, this has been around for a while, so I wonder why it's trending now. They haven't put out any recent updates afaik

I just wish it would go based on ambient light if you have a webcam rather than what the sun is doing. Where I work, I'm not always exposed to natural sunlight, and I don't always work during the day going into the night where I'm going to want my screen to adjust to me trying to fall asleep halfway through a second-shift schedule.

Whenever Flux gets mentioned, there's two groups of people: 1: Doesn't understand it, hates the "wrong" colors. Can't get used to it. 2: Appreciates the candle-like colors, says it helps them sleep in the evening or relaxes their eyes. I wonder if there's some sort of genetic difference? Maybe some people just aren't sensitive to bright light in the evening?

I wonder if there are also geographic differences at play? I love it during summer in Germany (= bright until ~10PM) but it annoys me when it turns dark at 4PM, while I am still at work.

I used to have the same issue as you.

F.lux emulates an undergoing sun. That doesn't happen in 20 seconds. Set the transition time to Slow.

Also select the right type of lighting. If none of the types match your lighting, juggle a bit with the settings until your screen looks the same way a piece of paper would look in the same lighting.

If you do that, you won't notice it's running at all. The only reason I turn it off is when I'm watching a movie. The colours in a movie usually already take darkness in account.

Surprised nobody brings up the line in the footer, which seems pretty important:

> F.lux is patent pending.

So they're applying for software patents on this so-far-free piece of software that has an open-source linux equivalent?

I've also installed redshift and redshift-gtk as suggested and they both crash on start. Altough redshift doesn't if supplied with all the required parameters outright.

Create a config file in ~/.config/redshift.conf with the manual parameters you use, and redshift-gtk should work.

Sample config is at http://jonls.dk/2010/10/redshift-1-6-released/ - I only need to set lat and lon to get it to run, though I also have temp-night set for my personal preference.
