Re: f.lux install

The download is the xflux executable. Extract it and put in $PATH (/like /usr/bin).

Then you need to tell it where you are:

xflux --help

Welcome to xflux (f.lux for X)
This will only work if you're running X on console.

Usage: ./xflux [-z zipcode | -l latitude] [-g longitude] [-k colortemp (default 3400)] [-nofork]
protip: Say where you are (use -z or -l).

Today i started using an awesome application called f.lux.It makes the color of your computer's display adapt to the time of day, warm at night and like sunlight during the day.F.lux has linux, windows and mac binaries.But at the time being, linux binary does not have any gui, it is cli only.(Indeed it does not matter, it is so easy to use.And yes that image is not from linux binary XD )Here is how to get it working under ubuntu/linux :

Download and install flux :

$wget -c https://secure.herf.org/flux/xflux.tgz
$tar -xvzf xflux.tgz
$rm -rf xflux.tgz
$sudo cp xflux /usr/bin/
$sudo chmod 755 /usr/bin/xflux

Now you can run flux with xflux command, you can also add it to your start up, But first you have to define your zipcode or latitude.Example :

$xflux -l 33.55, 44.55

When i am posting this blog post, the f.lux does not support latitude over 60.

Or you can define zipcode -z instead of -l

Now add it to your startup :

System > Preferences > Sessions

Name : Xflux
Command : xflux -l 33.55, 44.55 (DO NOT FORGET TO CHANGE the latitude or Zip!)
Comment : F.lux , Better lighting For Your Computer
So basically you have to add the command to your session startup.

Re: f.lux install

That was easy, thank you but it seems to always seems to be at 3400

1005 ~/bin\>xflux -l 09 -g 82

Welcome to xflux (f.lux for X)
This will only work if you're running X on console.

Your location (lat, long) is 9.0, 82.0

Your night-time color temperature is 3400
Going to background: 'kill 5829' to turn off.

1006 ~/bin\>

Re: f.lux install

Does anyone know how to do this for KDE?

I've been tinkering around the system settings to no avail. I even tried entering xflux -z 98109 as a start up script and that didn't work either.

I've been wondering the same thing. I use KDE and f.lux doesn't work.

I got it to work, I just needed to do the code as suggested originally, but replacing the file with xflux64
Anybody asking how to do this for KDE, it should be installed through Konsole no problem, just make sure you have the 64 bit version if applicable.
