Hi, is there any update about this problem? I'm still experiencing this issue on laptop.
Using Linux dell-xps 3.12.0-031200-generic #201311031935 SMP Mon Nov 4 00:36:54 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux and Distributor ID: Ubuntu Description: Ubuntu 12.04.3 LTS Release: 12.04 Codename: precise -- 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/840707 Title: screen brightness adjustment keys incorrectly reset brightness to 100% after login Status in “gnome-settings-daemon” package in Ubuntu: Confirmed Bug description: I have screen brightness set to about 30% in gnome-control-center's Screen app. After I first login, the first time I press a brightness adjustment key, brightness is reset to 100%. Subsequent adjustments work correctly. It appears that the adjustment script is not reading the correct setting the first time, but stores it for subsequent adjustment events. Another behaviour probably related to this: if I say turn the brightness down to minimum and then switch to a guest session via the indicator-session menu, when I switch back the brightness is set to full. If I press either brightness adjustment key, it immediately resets the brightness back to minimum. So upower is using its locally stored setting, but it does not match the current setting.
