Brightness is managed by gnome-settings-daemon. This report seems similar to bug 2081294 which was reported for oracular and fixed in 47.1.
I haven't checked if noble also is affected, but either way we need more information. My suggestion would simply be to run ubuntu-bug 2082162 to attach the data. ** Package changed: gnome-shell (Ubuntu) => gnome-settings-daemon (Ubuntu) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2082162 Title: after updating , brightness is not working To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-settings-daemon/+bug/2082162/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
