Redshift isn't working

[TangleCrow]

After installing redshift (the normal one) I get this message when I try to run it from the terminal:

(process:22331): GLib-GObject-CRITICAL **: g_type_instance_get_private: assertion `instance != NULL && instance->g_class != NULL' failed
Segmentation fault (core dumped)

And yeah, obviously Redshift isn't working... Can anyone help me out?

Doesn't work on my box, with either "redshift" or "gtk-redshift". Same error. Looks like the developer has a bug in his code.

Set color temperature of display according to time of day.

-o One shot mode (do not continously adjust color temperature)
-O TEMP One shot manual mode (set color temperature)
-x Reset mode (remove adjustment from screen)
-r Disable temperature transitions
-t DAY:NIGHT Color temperature to set at daytime/night

The neutral temperature is 6500K. Using this value will not
change the color temperature of the display. Setting the
color temperature to a value higher than this results in
more blue light, and setting a lower value will result in
more red light.

Default values:

Daytime temperature: 5500K
Night temperature: 3700K

Working at here, with the manual " -l LAT:LON".

Do you guys know about any programs that you can use instead of redshift? Redshift worked perfectly on my old Ubuntu 11.04 installation...

I haven't tried this but it may work:

Edit: I've installed it on my desktop and set my lat and long, but I'll have to wait till dark (I don't want to change my clock) to see if a/o how it works.

Thanks mate!

I downloaded and installed it too. It worked, but it really ought to be in the repos. Especially since the standard redshift presumably don't work with Kubuntu. (I've used it in other 12.04 'buntus without problems.)

It appears to "go red" on a schedule on my machine regardless of the lat/long setting. Watever it's defaulting to is on the other side of the globe from me as my screens were bright last night and are dark this afternoon...
