The same bug occurs for me using the linux-image-generic kernel version 3.5.0-26. I experience frequent apport error messages (I had to turn it off), degraded performance, and GPU hangs which necessitate a reboot. I am now using 3.5.0-23-generic, and the problem no longer occurs. I am using an Intel Core i7 with a 2nd Generation Core Processor Family Integrated Graphics Controller.
As a workaround, tell GRUB to boot an older kernel. You may need to hold SHIFT at startup to get the GRUB menu to appear. Select the "Advanced options for Ubuntu" in order to access your list of old kernels. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to xserver-xorg-video-intel in Ubuntu. https://bugs.launchpad.net/bugs/1157649 Title: GPU hang Status in “xserver-xorg-video-intel” package in Ubuntu: Incomplete Bug description: GPU hang ProblemType: Bug DistroRelease: Ubuntu 12.10 Package: xorg 1:7.7+1ubuntu4 ProcVersionSignature: Ubuntu 3.5.0-26.42-generic 3.5.7.6 Uname: Linux 3.5.0-26-generic x86_64 .tmp.unity.support.test.0: ApportVersion: 2.6.1-0ubuntu10 Architecture: amd64 CompizPlugins: No value set for `/apps/compiz-1/general/screen0/options/active_plugins' CompositorRunning: compiz Date: Wed Mar 20 11:42:11 2013 DistUpgraded: Fresh install DistroCodename: quantal DistroVariant: ubuntu ExtraDebuggingInterest: Yes, if not too technical GraphicsCard: Intel Corporation 2nd Generation Core Processor Family Integrated Graphics Controller [8086:0106] (rev 09) (prog-if 00 [VGA controller]) Subsystem: Toshiba America Info Systems Device [1179:fb30] InstallationDate: Installed on 2013-02-01 (46 days ago) InstallationMedia: Ubuntu 12.10 "Quantal Quetzal" - Release amd64 (20121017.5) MachineType: TOSHIBA SATELLITE PRO C850-1CU MarkForUpload: True ProcKernelCmdLine: BOOT_IMAGE=/boot/vmlinuz-3.5.0-26-generic root=UUID=c4b7d602-2fba-44b2-bb49-e583fb9b991d ro plymouth:debug=1=1=1=1=1 plymouth:debug drm.debug=0xe =1=1=1=1=1=1=1 SourcePackage: xorg UpgradeStatus: No upgrade log present (probably fresh install) dmi.bios.date: 06/27/2012 dmi.bios.vendor: Insyde Corp. dmi.bios.version: 1.60 dmi.board.asset.tag: Type2 - Board Asset Tag dmi.board.name: Type2 - Board Product Name1 dmi.board.vendor: Type2 - Board Vendor Name1 dmi.board.version: Type2 - Board Version dmi.chassis.asset.tag: No Asset Tag dmi.chassis.type: 10 dmi.chassis.vendor: OEM Chassis Manufacturer dmi.chassis.version: OEM Chassis Version dmi.modalias: dmi:bvnInsydeCorp.:bvr1.60:bd06/27/2012:svnTOSHIBA:pnSATELLITEPROC850-1CU:pvrPSKCBE-003003IT:rvnType2-BoardVendorName1:rnType2-BoardProductName1:rvrType2-BoardVersion:cvnOEMChassisManufacturer:ct10:cvrOEMChassisVersion: dmi.product.name: SATELLITE PRO C850-1CU dmi.product.version: PSKCBE-003003IT dmi.sys.vendor: TOSHIBA version.compiz: compiz 1:0.9.8.6-0ubuntu1 version.ia32-libs: ia32-libs N/A version.libdrm2: libdrm2 2.4.39-0ubuntu1 version.libgl1-mesa-dri: libgl1-mesa-dri 9.0.2-0ubuntu0.1 version.libgl1-mesa-dri-experimental: libgl1-mesa-dri-experimental N/A version.libgl1-mesa-glx: libgl1-mesa-glx 9.0.2-0ubuntu0.1 version.xserver-xorg-core: xserver-xorg-core 2:1.13.0-0ubuntu6.1 version.xserver-xorg-input-evdev: xserver-xorg-input-evdev 1:2.7.3-0ubuntu2 version.xserver-xorg-video-ati: xserver-xorg-video-ati 1:6.99.99~git20120913.8637f772-0ubuntu1 version.xserver-xorg-video-intel: xserver-xorg-video-intel 2:2.20.9-0ubuntu2 version.xserver-xorg-video-nouveau: xserver-xorg-video-nouveau 1:1.0.2-0ubuntu3 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/1157649/+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
