Comment 28 for bug 868904

Above mentioned work around works without active internet connection. i.e, redshift doesn't go looking for geolocations if you use this workaround.

But if we tuse terminal and use command : $ redshift
(it shows)

** (process:3248): WARNING **: Metadata for error domain "geoclue-error-quark" already registered

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.

But when you type command $ gtk-redshift -l LAT:LONG (Where LAT and LONG correspond with your coordinates.)
it runs soomthly as send in the above question. Hence forth a startup application is created using this command.

By the way when you click Applications>Accessories>Redshift it works through geolocation and needs a active internet connection every time where as the little workout in http://askubuntu.com/questions/194525/does-redshift-need-active-internet-connection-to-work/194582#194582 helps the otherway by mannually creating the geolocation.
