Dayana, thank you for reporting this and helping make Ubuntu better. 1) Could you please provide the full computer model as noted on the sticker of the computer itself (not from the Bug Description, or the result of a terminal command)?
2) Is this something that stopped working after an update? If so, which? 3) To see if this is already resolved in Ubuntu, could you please test http://cdimage.ubuntu.com/daily-live/current/ and advise to the results? ** Changed in: xorg (Ubuntu) Importance: Undecided => Low ** Changed in: xorg (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to xorg in Ubuntu. https://bugs.launchpad.net/bugs/1722622 Title: Brightness Status in xorg package in Ubuntu: Incomplete Bug description: I can't change the brightness ProblemType: Bug DistroRelease: Ubuntu 14.04 Package: xorg 1:7.7+1ubuntu8.1 ProcVersionSignature: Ubuntu 3.13.0-132.181-generic 3.13.11-ckt39 Uname: Linux 3.13.0-132-generic x86_64 .tmp.unity.support.test.0: ApportVersion: 2.14.1-0ubuntu3.25 Architecture: amd64 CompizPlugins: [core,composite,opengl,compiztoolbox,decor,vpswitch,snap,mousepoll,resize,place,move,wall,grid,regex,imgpng,session,gnomecompat,animation,fade,staticswitcher,workarounds,scale,expo,ezoom,dbus] CompositorRunning: compiz CompositorUnredirectDriverBlacklist: '(nouveau|Intel).*Mesa 8.0' CompositorUnredirectFSW: true CurrentDesktop: Unity Date: Tue Oct 10 21:51:19 2017 DistUpgraded: 2017-10-09 23:27:38,749 DEBUG enabling apt cron job DistroCodename: trusty DistroVariant: ubuntu ExtraDebuggingInterest: Yes, if not too technical GraphicsCard: Intel Corporation Atom Processor Z36xxx/Z37xxx Series Graphics & Display [8086:0f31] (rev 0c) (prog-if 00 [VGA controller]) Subsystem: Hewlett-Packard Company Device [103c:2213] InstallationDate: Installed on 2017-10-06 (3 days ago) InstallationMedia: Ubuntu 14.04.1 LTS "Trusty Tahr" - Release amd64 (20140722.2) MachineType: Hewlett-Packard HP 15 Notebook PC ProcKernelCmdLine: BOOT_IMAGE=/boot/vmlinuz-3.13.0-132-generic root=UUID=f74ed4d8-459a-4372-9992-efa8be3f558e ro quiet splash vt.handoff=7 SourcePackage: xorg UpgradeStatus: Upgraded to trusty on 2017-10-09 (0 days ago) dmi.bios.date: 05/26/2015 dmi.bios.vendor: Insyde dmi.bios.version: F.39 dmi.board.asset.tag: Type2 - Board Asset Tag dmi.board.name: 2213 dmi.board.vendor: Hewlett-Packard dmi.board.version: 57.54 dmi.chassis.asset.tag: Chassis Asset Tag dmi.chassis.type: 10 dmi.chassis.vendor: Hewlett-Packard dmi.chassis.version: Chassis Version dmi.modalias: dmi:bvnInsyde:bvrF.39:bd05/26/2015:svnHewlett-Packard:pnHP15NotebookPC:pvr0991100000000000000600087:rvnHewlett-Packard:rn2213:rvr57.54:cvnHewlett-Packard:ct10:cvrChassisVersion: dmi.product.name: HP 15 Notebook PC dmi.product.version: 0991100000000000000600087 dmi.sys.vendor: Hewlett-Packard version.compiz: compiz 1:0.9.11.3+14.04.20160425-0ubuntu1 version.ia32-libs: ia32-libs N/A version.libdrm2: libdrm2 2.4.67-1ubuntu0.14.04.2 version.libgl1-mesa-dri: libgl1-mesa-dri 10.1.3-0ubuntu0.6 version.libgl1-mesa-dri-experimental: libgl1-mesa-dri-experimental N/A version.libgl1-mesa-glx: libgl1-mesa-glx 10.1.3-0ubuntu0.6 version.xserver-xorg-core: xserver-xorg-core 2:1.15.1-0ubuntu2.9 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 2:2.99.910-0ubuntu1.7 version.xserver-xorg-video-nouveau: xserver-xorg-video-nouveau 1:1.0.10-1ubuntu2 xserver.bootTime: Tue Oct 10 21:42:38 2017 xserver.configfile: default xserver.errors: xserver.logfile: /var/log/Xorg.0.log xserver.outputs: product id 5547 vendor CMN xserver.version: 2:1.15.1-0ubuntu2.9 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1722622/+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
