I have a problem running a program called Redshift. When I open it it closes immediately. Here is the error when I try to run it from the terminal:

$ redshift 

(process:3525): GLib-GObject-CRITICAL **: g_type_instance_get_private: 
    assertion `instance != NULL && instance->g_class != NULL' failed
Segmentation fault (core dumped)

Looks like an error in that redshift program. Where is it from, how did you install it, can you give us more information on it? Is it that color-changing thing that helps you sleep? –  Nanne Nov 12 '12 at 13:51
    
Redshift the game? You should include more details Do you have the proprietary drivers for you card installed ? –  Caustic Nov 12 '12 at 14:06

It might be redshift which can't figure out your location, as I believe it uses the Gnome-clock to do this.

Try go to http://www.getlatlon.com/ and type in your city. Then use the shown lat-/longitude in a terminal command as following:

redshift -l x:y

x = latitude (ex. 56.15)
y = longitude (ex. 10.12)

ex:
redshift -l 56.16:10.12
