Introduction
This guide will help you to quickly configure blue light filter in Qubes OS with XFCE desktop environment.
Redshift
Installation
type sudo qubes-dom0-update redshift
in dom0 terminal and confirm installation by y
!
Remember that installing anything in dom0 is not recommended for security reasons
Configuration
Create confiig file - dom0 terminal:
-
cd .config
-
nano redshift.conf
You will create an empty file in path~/.config/redshift.conf
. Here you have to set values:
your location*, Day/Night Color. Here is explained sample with more functionality.
Basic configuration looks like:[redshift] temp-day=6400 temp-night=3200 adjustment-method=randr location-provider=manual [manual] lat=xx.xxxxx lon=xx.xxxxx
Where xx.xxxxx are my city latitude and longitude
- Save this configuration file
- Type
redshift
in dom0 to start the program. It will load previously saved configuration.
*Location is needed to know when actually sun sets for you. Without that parameter, redshift may not work.
To find city longitude and latitude you can use geonames.org
Automation/Startup
we need to create script ~/.startupscripts/redshift.sh
, open dom0 terminal
-
mkdir .startupscripts
-
cd .startupscripts
-
nano redshift.sh
-
paste:
#!/bin/sh sleep 2 redshift
-
save
-
chmod +x redshift.sh
- (this makes script executable) -
Add
redshift
to autostart in xfce settingsName: Redshift
Description: Blue light filter
Command: sh /home/USERNAME/.startupscripts/redshift.sh
