Just pick another country that is “close” and has similar latitude. I suggest not to give your true location because crackers after this guide has been written may use this file to know your location. To find city longitude and latitude you can use You can always check it, read the archwiki. In ordinary Linux system, redshift uses location services like geoclue but i don’t know if it’ll work on qubes as dom0 shouldn’t have internet access and the location provider needs IP to determine your location. Without that parameter, redshift may not work. *Location is needed to know when actually sun sets for you. Type sudo qubes-dom0-update redshift-gtk in dom0 terminal and confirm installation by y Configuration Type sudo qubes-dom0-update redshift in dom0 terminal and confirm installation by y This guide will help you to quickly configure blue light filter in Qubes OS Manage Redshift using GUI on system tray.If You want to copy this to the Qubes OS documentation, sure it’ll be faster to find. This may help your eyes hurt less if you are working in front of the screen at night. GitHub - jonls/redshift: Redshift adjusts the color temperature of your screen according to your surroundings. We need to create script ~/.startupscripts/redshift.sh, open dom0 terminalĬhmod +x redshift.sh - (this makes script executable)Īdd redshift to autostart in xfce settingsĬommand: sh /home/USERNAME/.startupscripts/redshift.sh To find city longitude and latitude you can use Automation/Startup It will load previously saved configuration. Type redshift in dom0 to start the program.Where xx.xxxxx are my city latitude and longitude Here is explained sample with more functionality.īasic configuration looks like: You will create an empty file in path ~/.config/nf. Remember that installing anything in dom0 is not recommended for security reasons Configuration Type sudo qubes-dom0-update redshift in dom0 terminal and confirm installation by y ! Some side effects are : you won't have a GUI to suspend Redshift or to disable it there will be no transitions (it will change directly from DAY_TEMP to NIGHT_TEMP) and that can be surprising if not unpleasant.This guide will help you to quickly configure blue light filter in Qubes OS with XFCE desktop environment. Change /home/USER to your home directory.Įxit your editor : if you did step 1., press Ctrl+ X then Y and finally Enter.ĭon't forget to remove Redshift from Startup Applications. > /home/USER/cron.log 2>&1 redirects the (error) messages to /home/USER/cron.log (that can be useful if your display is NOT on :0).redshift -O TEMPERATURE is the command we saw above, of course change DAY_TEMP and NIGHT_TEMP to the temperatures you want for the day and for the night.Don't change it unless you are using an external monitor, most of the time the default display port is :0. DISPLAY=:0 is for running the command on a display (otherwise it is on background, which is useless in our case).The commands that follow are what is executed at the (previously) specified time : , 55) between 17:00 and 7:59 everyday, and the second command (for day time) every 5 minutes between 8:00 and 16:59. So, in my example, the first command (for night time) is executed every 5 minutes (0, 5. * * * is the date (so every day, every month, and every day of the week).17-7 and 8-16 are the hour range (every hour between 5 p.m.*/5 is the interval in minutes (every minute that can be divided by 5).Go to the end of the file and add this lines: */5 17-7 * * * DISPLAY=:0 redshift -O NIGHT_TEMP > /home/USER/cron.log 2>&1 If you don't know how to use Vim (if you do you can jump this step), open a terminal ( Ctrl+ Alt+ T) and change the default editor by running echo "export EDITOR=nano" > ~/.bashrc Set the temperature at TEMPERATURE only once (Redshift won't run in background to compute if it as to change the temperature all the time). The command I use : redshift -O TEMPERATURE What I did was set up a cron task to set the colour temperature every x minutes, according to the hour. Redshift doesn't provide an option to set day and night time.
