This may help your eyes hurt less if you are working in front of the screen at night. -Download --------- +Run `redshift -h' for help on command line options. You can run the program +as `gtk-redshift' instead of 'redshift' for a graphical status icon. -Latest release is redshift 1.3 published on 2010-05-12. There are also -packages available for some distributions: - - * Ubuntu: Packages for Ubuntu Karmic. - * Gentoo: Redshift is in the Sunrise overlay. - -What is it? ------------ - -The program uses an X server extension to adjust the color -temperature. This is done by setting appropriate gamma ramps. If you -have configured your own gamma ramps they will be overwritten but in -that case you probably care too much about color accuracy to use this -program anyway. Your graphics driver and X server needs to either -support at least RANDR version 1.3 or the VidMode extension. - -The color temperature is set according to the position of the sun. A -different color temperature is set during night and daytime. During -twilight and early morning, the color temperature transitions smoothly -from night to daytime temperature to allow your eyes to slowly -adapt. At night the color temperature should be set to match the lamps in your -room. This is typically a low temperature at around 3000K--4000K -(default is 3700K). During the day, the color temperature should match -the light from outside, typically around 5500K--6500K (default is -5500K). The light has a higher temperature on an overcast day. - -How does it work? ------------------ - -Redshift will continously update the color temperature at regular -intervals. One shot mode can be selected if you only want to do one -adjustment. The color adjustments done by Redshift can be temporarily -toggled on and off by sending it the USR1 signal: - - $ killall -USR1 redshift - -The command line options are explained in the following paragraphs. The -only required parameter is your current location, all other options -have reasonable defaults. - - -h Display help message. - -v Verbose output. - - -g R:G:B Additional gamma correction to apply. Can also be - specified as -g GAMMA to set all channels to the same - gamma value. - -l LAT:LON Your current location in latitudes and longitudes. - -m METHOD Method to use to set color temperature (randr or - vidmode). Default is randr. In some cases one of the - methods will not work. In that case you may be able to - use the other method. - -o One shot mode. Do not continously adjust color - temperature. - -r Disable temperature transition. By default the program - will make a smooth transition to the desired color - temperature when the program is started and stopped. - -s SCREEN X screen to apply adjustments to. - -c CRTC CRTC to apply adjustments to (RANDR only) - -t DAY:NIGHT Color temperature to set at daytime/night. - -Example (location is Copenhagen, Denmark): - - $ redshift -l 55.7:12.6 -t 5700:3600 -g 0.8 -m vidmode -v - -Status icon ------------ - -Start the program gtk-redshift instead of redshift, with the same -arguments as you would pass to redshift. This will create an icon for -Redshift in the system tray. The icon will allow you to toggle -Redshift on and off. Thanks goes to the Tango Desktop Project for the -icon. gtk-redshift requires at least Python 2.6 and PyGTK 2.12. +Website: http://jonls.dk/redshift/ +Project page: http://launchpad.net/redshift |
