** Description changed: Function backlight keys work both when plugged/unplugged. AC adapter seems correctly detected (battery icon displays when I unplug) I tried with out success: GRUB_CMDLINE_LINUX_DEFAULT="acpi_osi=Linux acpi_backlight=vendor" and also GRUB_CMDLINE_LINUX_DEFAULT="acpi_osi=Linux" ProblemType: Bug DistroRelease: Ubuntu 14.04 Package: unity-control-center 14.04.3+14.04.20140604-0ubuntu1 ProcVersionSignature: Ubuntu 3.13.0-36.63-generic 3.13.11.6 Uname: Linux 3.13.0-36-generic x86_64 NonfreeKernelModules: wl ApportVersion: 2.14.1-0ubuntu3.4 Architecture: amd64 CurrentDesktop: Unity Date: Thu Sep 25 13:14:25 2014 InstallationDate: Installed on 2014-07-17 (69 days ago) InstallationMedia: Ubuntu 14.04 LTS "Trusty Tahr" - Release amd64 (20140417) SourcePackage: unity-control-center UpgradeStatus: No upgrade log present (probably fresh install) usr_lib_unity-control-center: - activity-log-manager 0.9.7-0ubuntu14 - deja-dup 30.0-0ubuntu4 + activity-log-manager 0.9.7-0ubuntu14 + deja-dup 30.0-0ubuntu4 + + Additional info: + Trying to find on my own, I discovered that the luminosity slider in unity-control-center Luminosity and Lock applet is ineffective, either actuated with mouse and keyboard left/right arrows. The slider moves, but luminosity doesn't follow it. + I also noticed that the luminosity setting, when set with the Fn Keys, is recorded without control of the current power supply mode, which allows to store a lower setting when on AC than it is recorded when on DC.... which was the reason of my symptom. + Maybe a simple change in the window text would make users aware of what they are actually setting: "Luminosity for current ([AC|Battery]) mode"... without preventing them to experiment what was my issue, for any reason (test or any strange reason) they would like it.
