Package: redshift-gtk Version: 1.11-1 Followup-For: Bug #873240 Hi Paul,
Are you running Gnome on wayland? You can check with echo $XDG_SESSION_TYPE Currently, redshift (using xrandr) does not work on wayland. As a workaround, you can can either choose ‘Gnome on X.org’ in GDM or you give Gnome Night Light a try, which is available in Gnome 3.24. Best, Marcel
