It's true the login screen runs as a separate user so is not affected by your own settings, but the example you give makes no sense:
> left for a few mins, came back and got flashbanged by my login screen That's the lock screen, not login screen. And the lock screen does (should) follow your personal settings. If you did indeed see the login screen when it should have been the lock screen then the shell must have crashed so please follow: https://wiki.ubuntu.com/Bugs/Responses#Missing_a_crash_report_or_having_a_.crash_attachment If you saw the lock screen then that sounds like a failure to apply the Night Light gamma changes, like bug 2025006. Please attach a photo of the problem so we can confirm. If it's just the example in the description that's incorrect then please just delete that. ** Changed in: gdm3 (Ubuntu) Status: Triaged => Incomplete ** Changed in: gnome-control-center (Ubuntu) Status: Triaged => Incomplete -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gnome-control-center in Ubuntu. https://bugs.launchpad.net/bugs/2097285 Title: Login screen does not adopt user's night mode settings To manage notifications about this bug go to: https://bugs.launchpad.net/gnome-control-center/+bug/2097285/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
