Undocked again just now to try to take a picture, and the problem did not recur; so it's an intermittent problem.

I was surprised to find that the moment I did so, the display on the LVDS output was corrupted. The moment I reconnected the HDMI display, the output on LVDS was normal again. Disconnecting the HDMI again, or manually reconfiguring outputs with gnome-control-center, the problem is reproducible. HDMI on, LVDS display is sane. HDMI off, LVDS output is garbled (looking like wrong striping or wrong interlacing or something). $ xrandr Screen 0: minimum 320 x 200, current 1680 x 1850, maximum 32767 x 32767 LVDS1 connected 1280x800+400+1050 (normal left inverted right x axis y axis) 261mm x 163mm 1280x800 60.0*+ 50.0 1024x768 60.0 800x600 60.3 56.2 640x480 59.9 VGA1 disconnected (normal left inverted right x axis y axis) 1680x1050 60.0 1280x800 60.0 HDMI1 connected 1680x1050+0+0 (normal left inverted right x axis y axis) 473mm x 296mm 1680x1050 60.0*+ 1280x1024 75.0 60.0 1440x900 75.0 59.9 1280x960 60.0 1280x800 59.9 1152x864 75.0 1024x768 75.1 70.1 60.0 832x624 74.6 800x600 72.2 75.0 60.3 56.2 640x480 72.8 75.0 66.7 60.0 720x400 70.1 DP1 disconnected (normal left inverted right x axis y axis) ProblemType: Bug DistroRelease: Ubuntu 13.04 Package: xserver-xorg-video-intel 2:2.21.4-0ubuntu1 Uname: Linux 3.9.0-030900rc2-generic x86_64 .tmp.unity.support.test.0: ApportVersion: 2.9.1-0ubuntu1 Architecture: amd64 CompizPlugins: [core,composite,opengl,compiztoolbox,decor,imgpng,snap,place,grid,resize,regex,mousepoll,gnomecompat,unitymtgrabhandles,vpswitch,move,animation,expo,session,wall,ezoom,staticswitcher,workarounds,fade,scale,unityshell] CompositorRunning: compiz CompositorUnredirectDriverBlacklist: '(nouveau|Intel).*Mesa 8.0' CompositorUnredirectFSW: true Date: Fri Mar 15 16:24:00 2013 DistUpgraded: 2013-01-25 08:16:10,776 WARNING no activity on terminal for 300 seconds (Configuring texlive) DistroCodename: quantal DistroVariant: ubuntu ExtraDebuggingInterest: Yes, including running git bisection searches GraphicsCard: Intel Corporation Core Processor Integrated Graphics Controller [8086:0046] (rev 02) (prog-if 00 [VGA controller]) Subsystem: Lenovo Device [17aa:215a] InstallationDate: Installed on 2010-09-24 (903 days ago) InstallationMedia: Ubuntu 10.04.1 LTS "Lucid Lynx" - Release amd64 (20100816.1) MachineType: LENOVO 3249CTO MarkForUpload: True PlymouthDebug: Error: [Errno 13] Permission denied: '/var/log/plymouth-debug.log' ProcKernelCmdLine: BOOT_IMAGE=/vmlinuz-3.9.0-030900rc2-generic root=/dev/mapper/hostname-root ro quiet splash --verbose vt.handoff=7 SourcePackage: xserver-xorg-video-intel UpgradeStatus: Upgraded to quantal on 2013-01-25 (49 days ago) dmi.bios.date: 08/23/2010 dmi.bios.vendor: LENOVO dmi.bios.version: 6QET52WW (1.22 ) dmi.board.name: 3249CTO 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:bvr6QET52WW(1.22):bd08/23/2010:svnLENOVO:pn3249CTO:pvrThinkPadX201:rvnLENOVO:rn3249CTO:rvrNotAvailable:cvnLENOVO:ct10:cvrNotAvailable: dmi.product.name: 3249CTO dmi.product.version: ThinkPad X201 dmi.sys.vendor: LENOVO version.compiz: compiz 1:0.9.9~daily13.03.08-0ubuntu1 version.ia32-libs: ia32-libs N/A version.libdrm2: libdrm2 2.4.42-0ubuntu2 version.libgl1-mesa-dri: libgl1-mesa-dri 9.0.2-0ubuntu1 version.libgl1-mesa-dri-experimental: libgl1-mesa-dri-experimental N/A version.libgl1-mesa-glx: libgl1-mesa-glx 9.0.2-0ubuntu1 version.xserver-xorg-core: xserver-xorg-core 2:1.13.2-0ubuntu3 version.xserver-xorg-input-evdev: xserver-xorg-input-evdev 1:2.7.3-0ubuntu2 version.xserver-xorg-video-ati: xserver-xorg-video-ati 1:7.1.0-0ubuntu1 version.xserver-xorg-video-intel: xserver-xorg-video-intel 2:2.21.4-0ubuntu1 version.xserver-xorg-video-nouveau: xserver-xorg-video-nouveau 1:1.0.6-0ubuntu3 xserver.bootTime: Fri Mar 15 00:29:32 2013 xserver.configfile: /etc/X11/xorg.conf xserver.errors: xserver.logfile: /var/log/Xorg.0.log xserver.version: 2:1.13.2-0ubuntu3 xserver.video_driver: intel To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/1155838/+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
