It seems redshift doesn't run without an active internet connection. If so, is there some way it could be run when there's no connection to the Internet?

6It's basically a bug in redshift. (Note that doesn't automatically make this off-topic) – Tom Brossman Sep 29 '12 at 19:07

Update: Please note that a fix is now on its way. You can either wait until it arrives in the official repositories or apply it yourself by following the advice in post #53 and on in the bug report.
As Anwar pointed out, Redshift fetches its geolocation data online by default. There is a workaround, though:
Manual configuration of geolocation data
a.) Using a config file
From the project's homepage:
Redshift will look for a configuration file in “~/.config/redshift.conf”. Here is an example:
; Global settings [redshift] temp-day=5700 temp-night=3500 transition=1 gamma=0.8:0.7:0.8 location-provider=manual adjustment-method=vidmode ; The location provider and adjustment method settings ; are in their own sections. [manual] lat=55.0 lon=12.0 ; In this example screen 1 is adjusted by vidmode. Note ; that the numbering starts from 0, so this is actually ; the second screen. [vidmode] screen=1`
Look for the directory provided above. If the configuration file doesn't exist, create one and append any custom options you like.
You will want to include location-provider=manual and modify lat= and long= with your location. This dialog will help you determine your coordinates.
b.) Using command-line arguments
Launch Startup Applications:
Find the Redshift entry in the startup app list and hit Edit. Under command enter the following string:
gtk-redshift -l LAT:LONG
Where LAT and LONG correspond with your coordinates. Hit save, then relog to activate Redshift.

I looked up for the config file. since it wasn't there i created one. setup location-provider=manual, and modify lat=8.51 & lon=76.96 set screen=0 since i use a laptop, restarted lap, still it doesn't seem working without connecting to net Thanks in advance – prasanna Sep 30 '12 at 4:10

What's the output when you start recoll from the command line (CTRL + ALT +T)?. Try the following command:
redshift -v -c '~/.config/redshift.conf'. – Glutanimate Sep 30 '12 at 5:08 -
And if that doesn't work either, try this:
redshift -v -l 8.5:77.0. – Glutanimate Sep 30 '12 at 5:12 -
also did you include the section headers (i.e.
[redshift]and[manual]) in your config file? – Glutanimate Sep 30 '12 at 5:23 -
- i had included the section headers i.e. [redshift] and [manual] in the config file. - the command redshift -v -c '~/.config/redshift.conf' doesn't work - but the second one worked: redshift -v -l 8.5:77.0 It showed : Location: 8.500000, 77.000000 Brightness: 1.00 Gamma: 1.000, 1.000, 1.000 Using method `randr'. Period: Daytime Color temperature: 6500K (ending in) Period: Daytime Color temperature: 5500K – prasanna Sep 30 '12 at 5:39
The answer is yes. Redshift requires active Internet connection. It depends on libgeoclue0 package which fetch geo location from Internet.
$ apt-cache depends redshift
redshift
Depends: libc6
Depends: libgconf2-4
Depends: libgeoclue0
Depends: libglib2.0-0
Depends: libx11-6
Depends: libxcb-randr0
Depends: libxcb1
Depends: libxxf86vm1
You can also verify this by running redshift from terminal. The terminal will display messages like
Started Geoclue provider `Geoclue Master'.
Using provider `geoclue'.
According to the geoclue provider we're at: 22.36, 91.80
Using method `randr'.
Which suggests, it is using Internet.
But, if you start redshift from terminal without Internet connection, the terminal will display these kinds of messages:
Started Geoclue provider `Geoclue Master'.
Using provider `geoclue'.
Could not get location (3 retries left): Geoclue master client has no usable Position providers.
Unable to get location from provider.

It showed first one. So there no way to use redshift when not connected to internet. – prasanna Sep 29 '12 at 19:04

The first one means, you have internet connection and redshift detects it. The line
According to geoclue provider we're at ...saying this. – Anwar Sep 29 '12 at 19:07 -
@prasanna If it answer your query, can you consider accepting the answer? – Anwar Sep 29 '12 at 19:14
