Title: Unity Screen Brightness Settings not Preserved on Reboot Status in Unity: Invalid Status in gnome-power-manager package in Ubuntu: Confirmed Status in unity package in Ubuntu: Invalid Bug description: Whenever Unity starts it sets the screen brightness to maximum, even when the laptop is on battery. Lowering the screen brightness doesn't persist across reboots. To reproduce: 1. Start laptop (in this case a Lenovo Yoga 2 Pro) in battery mode (i.e. disconnected from the AC adaptor) 2. Unity will start in maximum brightness. Lower brightness using keyboard brightness keys. 3. Shutdown laptop and start it back up again (still with the AC adapter disconnected) Expected result: The screen brightness settings should be preserved across reboots Actual result: After each new start Unity sets the screen brightness to maximum, meaning the user has to remember to manually reduce it or the battery will be quickly used up ProblemType: Bug DistroRelease: Ubuntu 14.04 Package: unity 7.2.3+14.04.20140826-0ubuntu1 ProcVersionSignature: Ubuntu 3.13.0-40.69-generic 3.13.11.10 Uname: Linux 3.13.0-40-generic x86_64 .tmp.unity.support.test.0: ApportVersion: 2.14.1-0ubuntu3.5 Architecture: amd64 CompizPlugins: [core,bailer,detection,composite,opengl,compiztoolbox,decor,imgpng,mousepoll,vpswitch,unitymtgrabhandles,gnomecompat,regex,move,grid,place,wall,animation,snap,resize,fade,session,expo,workarounds,scale,ezoom,unityshell] CompositorRunning: compiz CompositorUnredirectDriverBlacklist: '(nouveau|Intel).*Mesa 8.0' CompositorUnredirectFSW: true CurrentDesktop: Unity Date: Sat Nov 29 11:59:31 2014 DistUpgraded: Fresh install DistroCodename: trusty DistroVariant: ubuntu GraphicsCard: Intel Corporation Haswell-ULT Integrated Graphics Controller [8086:0a16] (rev 0b) (prog-if 00 [VGA controller]) Subsystem: Lenovo Device [17aa:3978] InstallationDate: Installed on 2014-09-16 (73 days ago) InstallationMedia: Ubuntu-Server 14.04 LTS "Trusty Tahr" - Release amd64 (20140416.2) MachineType: LENOVO 20266 ProcKernelCmdLine: BOOT_IMAGE=/vmlinuz-3.13.0-40-generic.efi.signed root=/dev/mapper/MainVG-root ro video.use_native_backlight=1 quiet splash vt.handoff=7 SourcePackage: unity UpgradeStatus: No upgrade log present (probably fresh install) dmi.bios.date: 03/25/2014 dmi.bios.vendor: LENOVO dmi.bios.version: 76CN35WW dmi.board.asset.tag: No Asset Tag dmi.board.name: Yoga2 dmi.board.vendor: LENOVO dmi.board.version: 31900058STD dmi.chassis.asset.tag: No Asset Tag dmi.chassis.type: 10 dmi.chassis.vendor: LENOVO dmi.chassis.version: Lenovo Yoga 2 Pro dmi.modalias: dmi:bvnLENOVO:bvr76CN35WW:bd03/25/2014:svnLENOVO:pn20266:pvrLenovoYoga2Pro:rvnLENOVO:rnYoga2:rvr31900058STD:cvnLENOVO:ct10:cvrLenovoYoga2Pro: dmi.product.name: 20266 dmi.product.version: Lenovo Yoga 2 Pro dmi.sys.vendor: LENOVO version.compiz: compiz 1:0.9.11.2+14.04.20140714-0ubuntu1 version.ia32-libs: ia32-libs N/A version.libdrm2: libdrm2 2.4.52-1 version.libgl1-mesa-dri: libgl1-mesa-dri 10.1.3-0ubuntu0.2 version.libgl1-mesa-dri-experimental: libgl1-mesa-dri-experimental N/A version.libgl1-mesa-glx: libgl1-mesa-glx 10.1.3-0ubuntu0.2 version.xserver-xorg-core: xserver-xorg-core 2:1.15.1-0ubuntu2.1 version.xserver-xorg-input-evdev: xserver-xorg-input-evdev 1:2.8.2-1ubuntu2 version.xserver-xorg-video-ati: xserver-xorg-video-ati 1:7.3.0-1ubuntu3.1 version.xserver-xorg-video-intel: xserver-xorg-video-intel 2:2.99.910-0ubuntu1.3 version.xserver-xorg-video-nouveau: xserver-xorg-video-nouveau 1:1.0.10-1ubuntu2 xserver.bootTime: Fri Nov 28 23:10:38 2014 xserver.configfile: default xserver.errors: xserver.logfile: /var/log/Xorg.0.log xserver.outputs: product id 16970 vendor SDC xserver.version: 2:1.15.1-0ubuntu2.1 To manage notifications about this bug go to: https://bugs.launchpad.net/unity/+bug/1397517/+subscriptions -- Mailing list: https://launchpad.net/~desktop-packages Post to : desktop-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~desktop-packages More help : https://help.launchpad.net/ListHelp
