OK, I think I see what is going on. It works, but I didn't understand what it does. I thought it was actually supposed to turn down the 'red' part of all colors in the display. It's just dimming the display slightly. So what I want to do is really eliminate the blue light from anything I run on my desktop. Submarine-style "rig for night running" mode. Is there a way to do that? Or will each program have to be individually configured to only use red colors? I suppose there is an all-red theme for XFCE, or one can be created. But the other programs might be more of a challenge.
It does turn down the color temperature, not just dim the display. I don't know what the problem is on your system, but I've never had any trouble with it.

The important part is the '-l' option to make it work:
$ LC_ALL=C redshift -h|grep '\-l'
Usage: redshift -l LAT:LON -t DAY:NIGHT [OPTIONS...]
-l LAT:LON Your current location
-l PROVIDER Select provider for automatic location updates
This was on a laptop using the default XFCE desktop, so there is no complex issue with ATI or nVidia drivers. Its the standard Intel video driver, and it's the desktop environment the whole system was designed around.
