====== Redshift Configuration ====== ===== Redshift ===== It is a program which adjusts the color temperature of your screen with GTK+ integration. Think about daylight and night light difference. From the developer's page: [[http://jonls.dk/redshift/]] Redshift adjusts the color temperature of your screen according to your surroundings. It has been in the repositories since Precise Pangolin 12.04, and you can install redshift-gtk additionnally to it. ===== Redshift-gtk ===== === Description === Redshift-gtk is a simple user interface. Once installed you will find it in the accessories menus. It is not installed as a dependency and isn't even a recommended package, for the time being. === What it does === It is used to start redshift, and once started, it sits in the tray to allow enabling and disabling redshift, suspend it for a while, or quit. This is all it does, and it does not provide a configuration of any kind. The man and help commands are not very helpful either, especially on the syntax needed for the latitude and longitude. ====== Configuration File ====== So here is an example of a working configuration, which you can adapt to your needs. Name it redshift.conf and place it in your $HOME/.config directory, then ajust it to your needs. [quote][redshift] # Set the day and night screen temperatures temp-day=5800 temp-night=4800 # Enable/Disable a smooth transition between day and night # 0 will cause a direct change from day to night screen temperature. # 1 will gradually increase or decrease the screen temperature transition=1 # Set the screen brightness. Default is 1.0 #brightness=0.9 # It is also possible to use different settings for day and night since version 1.8. #brightness-day=0.7 #brightness-night=0.4 # Set the screen gamma (for all colors, or each color channel individually) gamma=0.9 #gamma=0.8:0.7:0.8 # Set the location-provider: 'geoclue', 'gnome-clock', 'manual' # type 'redshift -l list' to see possible values # The location provider settings are in a different section. location-provider=manual # Set the adjustment-method: 'randr', 'vidmode' # type 'redshift -m list' to see all possible values # 'randr' is the preferred method, 'vidmode' is an older API # but works in some cases when 'randr' does not. # The adjustment method settings are in a different section. adjustment-method=randr # Configuration of the location-provider: # type 'redshift -l PROVIDER:help' to see the settings # e.g. 'redshift -l manual:help' [manual] lat=43 lon=1 # Configuration of the adjustment-method # type 'redshift -m METHOD:help' to see the settings # ex: 'redshift -m randr:help' # In this example, randr is configured to adjust screen 1. # Note that the numbering starts from 0, so this is actually the second screen. [randr] screen=0[/quote] Of course, you can play with the temp-day and temp-night values the gamma, and you will have to provide the correct values for "lat" and "lon" according to your geographical position.
