This bug affects me also... Two times a day I need to get to the tty1 and manually kill X Server because it hangs (or Compiz crashes and I lose window decorating. It seems that it occurs when I start a lot of intensive apps (like Firefox with ~12 tabs, Thunderbird and Gimp).
I am using Dell N5040 and this kind of usage (Firefox with ~12 tabs etc.) was just fine on 12.04. Graphic card is Intel® HD Graphics. -- 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/1060308 Title: [arrandale] GPU lockup IPEHR: 0x02000024 Status in “xserver-xorg-video-intel” package in Ubuntu: New Bug description: a problem the lib mesa ProblemType: Crash DistroRelease: Ubuntu 12.10 Package: xserver-xorg-video-intel 2:2.20.9-0ubuntu2 ProcVersionSignature: Ubuntu 3.5.0-13.14-generic 3.5.3 Uname: Linux 3.5.0-13-generic i686 ApportVersion: 2.6.1-0ubuntu1 Architecture: i386 Chipset: arrandale Date: Tue Oct 2 13:26:43 2012 DistroCodename: quantal DistroVariant: ubuntu DuplicateSignature: [arrandale] GPU lockup IPEHR: 0x02000024 Ubuntu 12.10 ExecutablePath: /usr/share/apport/apport-gpu-error-intel.py GpuHangFrequency: Very infrequently InstallationMedia: Ubuntu 12.10 "Quantal Quetzal" - Alpha i386 (20120905.2) InterpreterPath: /usr/bin/python3.2mu MachineType: LG Electronics C400-G.BG21P1 ProcCmdline: /usr/bin/python3 /usr/share/apport/apport-gpu-error-intel.py ProcEnviron: ProcKernelCmdLine: BOOT_IMAGE=/vmlinuz-3.5.0-13-generic root=/dev/mapper/ubuntu-root ro quiet splash vt.handoff=7 RelatedPackageVersions: xserver-xorg 1:7.7+1ubuntu3 libdrm2 2.4.39-0ubuntu1 xserver-xorg-video-intel 2:2.20.9-0ubuntu2 SourcePackage: xserver-xorg-video-intel Title: [arrandale] GPU lockup IPEHR: 0x02000024 UdevDb: Error: [Errno 2] No such file or directory: 'udevadm' UpgradeStatus: No upgrade log present (probably fresh install) UserGroups: dmi.bios.date: 05/25/2011 dmi.bios.vendor: INSYDE dmi.bios.version: QL7L3G11 dmi.board.asset.tag: Base Board Asset Tag dmi.board.name: Base Board Product Name dmi.board.vendor: Intel Corp. dmi.board.version: Base Board Version dmi.chassis.asset.tag: Chassis Asset Tag dmi.chassis.type: 1 dmi.chassis.vendor: Chassis Manufacturer dmi.chassis.version: Chassis Version dmi.modalias: dmi:bvnINSYDE:bvrQL7L3G11:bd05/25/2011:svnLGElectronics:pnC400-G.BG21P1:pvrTBD:rvnIntelCorp.:rnBaseBoardProductName:rvrBaseBoardVersion:cvnChassisManufacturer:ct1:cvrChassisVersion: dmi.product.name: C400-G.BG21P1 dmi.product.version: TBD dmi.sys.vendor: LG Electronics To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/1060308/+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
