Why I can't add redshift to startup?

  • 772

recently, I have discovery redshift (help your eyes hurt less if you are working in front of the screen at night)

I can run the tools using command line : redshift-gtk

I run "startup manager" : enter image description here

and I have add an entry :

enter image description here

And when I restart my computer, redshift does not start when I start my computer

startup

  1. You could add a cron job.

    Run the command:

    crontab -e

    Scroll to the bottom, and add this line

    @reboot redshift-gtk

    Then press enter (so you have a blank line below). That should now run at startup.

    According to this link, it is the result of a bug. However: as suggested on the page, you can try to install geoclue-hostip, which was a solution for at least some of the users.

    sudo apt-get install geoclue-hostip

    Note: geoclue-hostip was installed on my system, that could be the reason why I could not reproduce the problem.

  3. I had plenty of issues trying to get redshift-gtk to autostart on my laptop (running Mint KDE 18). In the end I manged to get the right systemd configuration settings...

    [Unit]
Description=Redshift display colour temperature adjustment
Documentation=http://jonls.dk/redshift/
After=display-manager.service

[Service]
Type=simple
Environment=DISPLAY=:0
ExecStart=/usr/bin/redshift-gtk -l 51.5:-0.1
Restart=on-failure
RestartSec=2

[Install]
WantedBy=default.target

    This should be saved as a user unit configuration file here:

    ~/.config/systemd/user/redshift-gtk.service

    You can test the above by running:

    systemctl --user start redshift-gtk

    You should be able to see redshift-gtk working, or you can check that it is working by running:

    systemctl --user status redshift-gtk

    NOTE: see the listing at the bottom for example output.

    Assuming the redshift-gtk service started correctly, you can set it to run automatically as part of the initial user login:

    systemctl --user enable redshift-gtk

    You can check that has worked correctly by running:

    systemctl --user list-dependencies default.target

    This should show something like the following (note the second line, directly below default.target):

    default.target
● ├─redshift-gtk.service
● └─basic.target
●   ├─paths.target
●   ├─sockets.target
●   └─timers.target

    Now when you restart you should see redshift-gtk working, but again you can check by running:

    systemctl --user status redshift-gtk

    Which should produce something like the following:

    ● redshift-gtk.service - Redshift display colour temperature adjustment
   Loaded: loaded (/home/robin/.config/systemd/user/redshift-gtk.service; enabled; vendor preset: enabled)
