In general the kernel doesn't choose the backlight level, it only applies the backlight level chosen by userspace. It's usually g-s-d that provides the brightness values to the kernel, so I'm moving the bug to that package. ** Package changed: linux (Ubuntu) => gnome-settings-daemon (Ubuntu) -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gnome-settings-daemon in Ubuntu. https://bugs.launchpad.net/bugs/1016724 Title: Laptop brightness always reverts to maximum on 12.04 Status in “gnome-settings-daemon” package in Ubuntu: Confirmed Bug description: Whenever I start my laptop the brightness is at maximum.

This bug affects all my G series and Envy series HP laptops, as well as my Dell. They all either have an AMD APU (all my HP laptops) or an i5 (the Dell). We had the same problem back in 11.10.

Thank you for taking the time to report this bug and helping to make Ubuntu better. The issue you are reporting is an upstream one and it would be nice if somebody having it could send the bug to the developers of the software by following the instructions at https://wiki.ubuntu.com/Bugs/Upstream/GNOME. If you have done so, please tell us the number of the upstream bug (or the link), so we can add a bugwatch that will inform us about its status.
