redshift - look after your eyes!

mrneilypops · 2015-11-08 18:08:23

Redshift adjusts the color temperature of your screen according to your surroundings. This may help your eyes hurt less if you are working in front of the screen at night.

sudo apt-get install redshift-gtk

copy config file from jonis.dk;
http://jonls.dk/redshift/

~/.config/redshift.conf

edit your latitude and longitude.
edit your preferred colour temperatures day and night.
note: for a single screen;
[randr]
screen=0

save config file and start redshift;

redshift

add to ~/.config/openbox/autostart
redshift &

ease those tired eyes

I've used f.lux in Windows and it works nice.

Might have to give this a look-see.

+1 for redshift. I read about it in Linux Voice and now use it on all of my BL installs. If you'd rather not be bothered with configuration files, also install redshift-gtk which provides a quick way to change the configuration of, or start/stop, redshift via a tray icon. I believe installing redshift-gtk will automatically install redshift as well.

Although not available in the repos, there's another one called blueshift, that offers more configuration options. Check it out here: https://github.com/maandree/blueshift. However, redshift meets my needs so I've not really looked into blueshift in any detail.

If you want simpler/lighter alternative this script (borrowed from the LinuxBBQ) is great too; no bloat, job done.

sudo mv bbqshift /usr/local/bin/
sudo chmod a+x /usr/local/bin/bbqshift

Wow, that is pretty nifty, thx for sharing Snap. Have to check this linuxbbq out sometime.

I installed redshift-gtk from synaptic.

Running the command (redshift-gtk) from the CLI does nothing. I found a command on the ArchWiki to run it, so I created a quick one line script to run it in the background:

#!/bin/bash
redshift -l LAT:LON &

Of course I put in my latitude and longitude instead of LAT/LON.

I heard rumours that redshift-gtk installs an item in my system tray, but I don't see it in my Tint2 panel.

Thoughts?

EDIT: Logging out and logging back in did nothing to change this behaviour. Perhaps all is working as intended? For now I am using my script, but having a GUI for it would be nice.

@Temetka
This is how I use redshift;
1. Install redshift via synaptic (redshift-gtk should give an icon in the tint2 systray)

Start the program redshift-gtk instead of redshift, with the same arguments as you would pass to redshift. This will create an icon for Redshift in the system tray. The icon will allow you to toggle Redshift on and off. Thanks goes to the Tango Desktop Project for the icon. Redshift GTK requires at least Python 3.2 (since Redshift 1.9).

2. Copy the sample redshift config file at jonls.dk to;
~/.config/redshift.conf
Edit conf file to your requirements...
3. Add;

redshift &

to ~/.config/openbox/autostart

I'm also part of the cult.. I love it .
(and it gets my lat lon through the ip address)

^ That's my fault. I was using Unstable when I checked synaptic. In Testing and Unstable, redshift-gtk is now a transitional dummy package. For Stable (Jessie), redshift-gtk is the correct package. I apologize to others who may have wasted their time trying to get gtk-redshift to work under Jessie.

^ Easy mistake to make, as in both cases the executable is redshift-gtk.

I'm trying it, but I'm not sure my eyes like it.

KrunchTime · 2015-11-12 21:49:59

^ Once you get used to it, you'll not want to be without it. My eyes didn't care much for it at first either.

ohnonot · 2015-11-13 07:06:09

i wouldn't say my eyes, but my sense of aesthetics doesn't like it... 8.(

pvsage · 2015-11-13 08:54:01

^ Same here. While I applaud the attempt at ergonomic color shifting, I prefer a consistent color temperature. I can't imagine watching films or cartoons, for example, with the monitor red-shifted to 3500K.

KrunchTime · 2015-11-13 09:10:09

Trust me...you'll get used to it. Of course, everyone is different. I'm even going to install f.lux in my Windows VMs because I love redshift so much.

@mrneilypops: Thank you.

I'm using 5500K for day/night (same as "Midday Sun" in f.lux) with no change to brightness and gamma=0.8:0.9:0.7.

On my ageing laptop this has an effect similar to Cinema mode on my TV.

wagmic · 2017-05-14 14:47:18

hi i put a launcher of redshift in my tint2 config in order to use it when i want .
just add for the "clock_rclick_command" this :

# Clock
time1_format = %H:%M
time1_font = Liberation Sans 9
#time2_format = %A %d %B
#time2_font = Liberation Sans 6
clock_font_color = #b5b5b5 100
clock_padding = 12 4
clock_background_id = 0
clock_lclick_command = gsimplecal
clock_rclick_command =redshift-gtk -l 33.578456:-7.606636 -t 6500K:3700K -g 0.8

this doesn't work with a conf file
