I think this might happen because the screen is off at 6am. So any attempt to change the gamma ramps (turn off night light) might fail and not be reattempted. That would be easy enough to fix if it was all in the gnome-shell process, but I suspect some of it is happening in the 'colord' or 'gsd-color' processes. Upstream the GNOME developers have expressed a plan to sort that out:
https://gitlab.gnome.org/GNOME/gnome-settings-daemon/-/issues/131 which might also help with this when done. ** Bug watch added: gitlab.gnome.org/GNOME/gnome-settings-daemon/-/issues #131 https://gitlab.gnome.org/GNOME/gnome-settings-daemon/-/issues/131 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1894596 Title: Night Light stays on To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/1894596/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
