Public bug reported: I was to connect external LCD to a Thinkpad X220T on the VGA port. The system was frozen and both internal and external LCD have a blank screen. The Cap lock LED on the keyboard was not functional. I have to force a poweroff to regain control of the computer.
What you expected to happen: The external LCD displayed screen correctly What happened instead The computer crashed and both screens were blank ProblemType: Bug DistroRelease: Ubuntu 11.10 Package: xorg 1:7.6+7ubuntu7.1 ProcVersionSignature: Ubuntu 3.0.0-17.30-generic 3.0.22 Uname: Linux 3.0.0-17-generic x86_64 .tmp.unity.support.test.0: ApportVersion: 1.23-0ubuntu4 Architecture: amd64 CompizPlugins: [core,bailer,detection,composite,opengl,compiztoolbox,decor,imgpng,vpswitch,move,place,unitymtgrabhandles,mousepoll,gnomecompat,wall,grid,resize,session,snap,regex,animation,expo,fade,ezoom,scale,workarounds,unityshell] CompositorRunning: compiz Date: Tue Apr 17 14:02:03 2012 DistUpgraded: Fresh install DistroCodename: oneiric DistroVariant: ubuntu DkmsStatus: tp-smapi, 0.41, 3.0.0-16-generic, x86_64: installed tp-smapi, 0.41, 3.0.0-17-generic, x86_64: installed ExtraDebuggingInterest: Yes, whatever it takes to get this fixed in Ubuntu GpuHangFrequency: This is the first time GpuHangReproducibility: Seems to happen randomly GpuHangStarted: Today GraphicsCard: Intel Corporation 2nd Generation Core Processor Family Integrated Graphics Controller [8086:0126] (rev 09) (prog-if 00 [VGA controller]) Subsystem: Lenovo Device [17aa:21db] InstallationMedia: Ubuntu 11.10 "Oneiric Ocelot" - Release amd64 (20111012) MachineType: LENOVO 429637U ProcKernelCmdLine: BOOT_IMAGE=/boot/vmlinuz-3.0.0-17-generic root=UUID=1183cf9c-0d9c-4d5b-87fc-dc6bb5bb1c7d ro quiet splash vt.handoff=7 SourcePackage: xorg Symptom: display Title: Xorg freeze UpgradeStatus: No upgrade log present (probably fresh install) dmi.bios.date: 12/01/2011 dmi.bios.vendor: LENOVO dmi.bios.version: 8DET56WW (1.26 ) dmi.board.asset.tag: Not Available dmi.board.name: 429637U dmi.board.vendor: LENOVO dmi.board.version: Not Available dmi.chassis.asset.tag: No Asset Information dmi.chassis.type: 10 dmi.chassis.vendor: LENOVO dmi.chassis.version: Not Available dmi.modalias: dmi:bvnLENOVO:bvr8DET56WW(1.26):bd12/01/2011:svnLENOVO:pn429637U:pvrThinkPadX220Tablet:rvnLENOVO:rn429637U:rvrNotAvailable:cvnLENOVO:ct10:cvrNotAvailable: dmi.product.name: 429637U dmi.product.version: ThinkPad X220 Tablet dmi.sys.vendor: LENOVO version.compiz: compiz 1:0.9.6+bzr20110929-0ubuntu6.1 version.ia32-libs: ia32-libs N/A version.libdrm2: libdrm2 2.4.26-1ubuntu1 version.libgl1-mesa-dri: libgl1-mesa-dri 7.11-0ubuntu3.2 version.libgl1-mesa-dri-experimental: libgl1-mesa-dri-experimental N/A version.libgl1-mesa-glx: libgl1-mesa-glx 7.11-0ubuntu3.2 version.xserver-xorg: xserver-xorg 1:7.6+7ubuntu7.1 version.xserver-xorg-input-evdev: xserver-xorg-input-evdev 1:2.6.0-1ubuntu13 version.xserver-xorg-video-ati: xserver-xorg-video-ati 1:6.14.99~git20110811.g93fc084-0ubuntu1 version.xserver-xorg-video-intel: xserver-xorg-video-intel 2:2.15.901-1ubuntu2.1 version.xserver-xorg-video-nouveau: xserver-xorg-video-nouveau 1:0.0.16+git20110411+8378443-1 ** Affects: linux (Ubuntu) Importance: Undecided Status: New ** Tags: amd64 apport-bug compiz-0.9 freeze oneiric running-unity ubuntu -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/983696 Title: kernel BUG at /build/buildd/linux-3.0.0/drivers/gpu/drm/i915/i915_gem.c:3336!
