How to install F.lux on Fedora 21

Overview:

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. source

I was confused to install f.ux on my Fedora 21. I tried on terminal, but not found with yum. Finally, I got solution on Fedora Forum. Here it was:

1. Download f.lux
$wget -c https://secure.herf.org/flux/xflux.tgz

2. Extract it. In this case, i used Archive Manager by GUI command

3. Copy extracted file to /usr/bin
$cp xflux /usr/bin

4. Change permission file
$chmod 755 /usr.bin/xflux

5. Run f.lux
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

6. Add on 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

that's all, thank you ^_^
