madhu, thank you for reporting this and helping make Ubuntu better. As per http://us.acer.com/ac/en/US/content/drivers an update to your computer's buggy and outdated BIOS is available (2.15). If you update to this following https://help.ubuntu.com/community/BIOSUpdate does it change anything?
If it doesn't, could you please both specify what happened, and provide the output of the following terminal command: sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date For more on BIOS updates and linux, please see https://help.ubuntu.com/community/ReportingBugs#Bug_reporting_etiquette . Please note your current BIOS is already in the Bug Description, so posting this on the old BIOS would not be helpful. As well, you don't have to create a new bug report. Once the BIOS is updated, and the information above is provided, then please mark this report Status New. Thank you for your understanding. ** Tags added: bios-outdated-2.15 ** Changed in: xorg (Ubuntu) Importance: Undecided =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/1485118 Title: please help me Status in xorg package in Ubuntu: Incomplete Bug description: display ligting ProblemType: Bug DistroRelease: Ubuntu 14.04 Package: xorg 1:7.7+1ubuntu8.1 ProcVersionSignature: Ubuntu 3.13.0-62.102-generic 3.13.11-ckt24 Uname: Linux 3.13.0-62-generic i686 .tmp.unity.support.test.0: ApportVersion: 2.14.1-0ubuntu3.12 Architecture: i386 CompizPlugins: No value set for `/apps/compiz-1/general/screen0/options/active_plugins' CompositorRunning: compiz CompositorUnredirectDriverBlacklist: '(nouveau|Intel).*Mesa 8.0' CompositorUnredirectFSW: true CurrentDesktop: Unity Date: Sat Aug 15 02:48:46 2015 DistUpgraded: Fresh install DistroCodename: trusty DistroVariant: ubuntu DkmsStatus: bbswitch, 0.7, 3.13.0-61-generic, i686: installed bbswitch, 0.7, 3.13.0-62-generic, i686: installed nvidia-340, 340.76, 3.13.0-61-generic, i686: installed nvidia-340, 340.76, 3.13.0-62-generic, i686: installed GraphicsCard: Intel Corporation 2nd Generation Core Processor Family Integrated Graphics Controller [8086:0106] (rev 09) (prog-if 00 [VGA controller]) Subsystem: Acer Incorporated [ALI] Device [1025:0506] InstallationDate: Installed on 2015-08-03 (11 days ago) InstallationMedia: Ubuntu 14.04.1 LTS "Trusty Tahr" - Release i386 (20140722.2) MachineType: Acer Aspire 4750 ProcKernelCmdLine: BOOT_IMAGE=/boot/vmlinuz-3.13.0-62-generic root=UUID=d8ae8d9b-5a3a-402a-8aa7-7c6d347ec4e9 ro quiet splash acpi_backlight=vendor vt.handoff=7 SourcePackage: xorg UpgradeStatus: No upgrade log present (probably fresh install) dmi.bios.date: 05/24/2011 dmi.bios.vendor: Phoenix Technologies Ltd. dmi.bios.version: V2.01 dmi.board.asset.tag: No Asset Tag dmi.board.name: Aspire 4750 dmi.board.vendor: Acer dmi.board.version: V2.01 dmi.chassis.asset.tag: No Asset Tag dmi.chassis.type: 9 dmi.chassis.vendor: Acer dmi.chassis.version: V2.01 dmi.modalias: dmi:bvnPhoenixTechnologiesLtd.:bvrV2.01:bd05/24/2011:svnAcer:pnAspire4750:pvrV2.01:rvnAcer:rnAspire4750:rvrV2.01:cvnAcer:ct9:cvrV2.01: dmi.product.name: Aspire 4750 dmi.product.version: V2.01 dmi.sys.vendor: Acer version.compiz: compiz 1:0.9.11.3+14.04.20150313-0ubuntu1 version.libdrm2: libdrm2 2.4.60-2~ubuntu14.04.1 version.libgl1-mesa-dri: libgl1-mesa-dri 10.1.3-0ubuntu0.4 version.libgl1-mesa-dri-experimental: libgl1-mesa-dri-experimental N/A version.libgl1-mesa-glx: libgl1-mesa-glx 10.1.3-0ubuntu0.4 version.xserver-xorg-core: xserver-xorg-core 2:1.15.1-0ubuntu2.7 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 2:2.99.910-0ubuntu1.6 version.xserver-xorg-video-nouveau: xserver-xorg-video-nouveau N/A xserver.bootTime: Fri Aug 14 22:30:48 2015 xserver.configfile: default xserver.errors: xserver.logfile: /var/log/Xorg.0.log xserver.outputs: product id 22 vendor INL xserver.version: 2:1.15.1-0ubuntu2.7 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1485118/+subscriptions -- Mailing list: https://launchpad.net/~desktop-packages Post to : [email protected] Unsubscribe : https://launchpad.net/~desktop-packages More help : https://help.launchpad.net/ListHelp
