Public bug reported: Binary package hint: xorg
When an external monitor is connected to my Thinkpad T400s using the Display Port connection, the monitor never goes into an energy saving state despite the Gnome power saving settings being enabled. Gnome screen saver activates, but this does not conserve energy of course. This bug occurs only when the laptop lid is closed. The bug does not occur when the laptop lid is open. I have seen this problem with Lucid, Maverick and now the latest daily build of Natty. ubuntu-bug xorg crashed, so I don't know if you received the extra information you need or not. I will include some information here that might be relevant, just in case: 00:02.0 VGA compatible controller: Intel Corporation Mobile 4 Series Chipset Integrated Graphics Controller (rev 07) (prog-if 00 [VGA controller]) Subsystem: Lenovo Device 20e4 Flags: bus master, fast devsel, latency 0, IRQ 45 Memory at f2000000 (64-bit, non-prefetchable) [size=4M] Memory at d0000000 (64-bit, prefetchable) [size=256M] I/O ports at 1800 [size=8] Expansion ROM at <unassigned> [disabled] Capabilities: [90] MSI: Enable+ Count=1/1 Maskable- 64bit- Capabilities: [d0] Power Management version 3 Kernel driver in use: i915 Kernel modules: i915 00:02.1 Display controller: Intel Corporation Mobile 4 Series Chipset Integrated Graphics Controller (rev 07) Subsystem: Lenovo Device 20e4 Flags: bus master, fast devsel, latency 0 Memory at f2400000 (64-bit, non-prefetchable) [size=1M] Capabilities: [d0] Power Management version 3 Linux version 2.6.38-1-generic (buildd@allspice) (gcc version 4.5.2 (Ubuntu/Linaro 4.5.2-2ubuntu1) ) #28-Ubuntu SMP Fri Jan 28 15:26:43 UTC 2011 I run the 64 bit versions of natty / maverick / lucid. $apt-cache policy xorg xorg: Installed: 1:7.5+6ubuntu8 Candidate: 1:7.5+6ubuntu8 Version table: *** 1:7.5+6ubuntu8 0 500 http://archive.ubuntu.com/ubuntu/ natty/main amd64 Packages 100 /var/lib/dpkg/status ProblemType: Bug DistroRelease: Ubuntu 11.04 Package: xorg 1:7.5+6ubuntu8 ProcVersionSignature: Ubuntu 2.6.38-1.28-generic 2.6.38-rc2 Uname: Linux 2.6.38-1-generic x86_64 Architecture: amd64 DRM.card0.DP.1: status: connected enabled: enabled dpms: On modes: 1920x1200 1600x1200 1680x1050 1600x1000 1280x1024 1280x1024 1280x960 1152x864 1024x768 1024x768 832x624 800x600 800x600 640x480 640x480 720x400 edid-base64: AP///////wAi8PkmAQEBAQ0TAQSlNiN47s5Qo1RMmSYPUFSla4CBQIGAqQCpQLMA0QABAQEBKDyAoHCwI0AwIDYAImAhAAAaAAAA/ABIUCBMUDI0NzV3CiAgAAAA/QAwVR5eFQQRUNL4WPAAAAAA/wBDTkM5MTMwUVgyCiAgAI0= DRM.card0.DP.2: status: disconnected enabled: disabled dpms: Off modes: edid-base64: DRM.card0.DP.3: status: disconnected enabled: disabled dpms: Off modes: edid-base64: DRM.card0.HDMI.A.1: status: disconnected enabled: disabled dpms: Off modes: edid-base64: DRM.card0.HDMI.A.2: status: disconnected enabled: disabled dpms: Off modes: edid-base64: DRM.card0.LVDS.1: status: connected enabled: enabled dpms: Off modes: 1440x900 1440x900 edid-base64: AP///////wAwrjZAAAAAAAASAQOAHhN46uWVk1ZPkCgoUFQAAAABAQEBAQEBAQEBAQEBAQEBwSmg5FGEGjAwIDYAL74QAAAZ3iKgLFGEfjAwIDYAL74QAAAZAAAADwCVCjKVCigeCQBMo0JUAAAA/gBMVE4xNDFCVDA4MDAxAMs= DRM.card0.VGA.1: status: disconnected enabled: disabled dpms: Off modes: edid-base64: Date: Tue Feb 1 05:22:05 2011 DistUpgraded: Fresh install DistroCodename: natty DistroVariant: ubuntu GdmLog1: Not present GdmLog2: Not present GraphicsCard: Subsystem: Lenovo Device [17aa:20e4] Subsystem: Lenovo Device [17aa:20e4] LiveMediaBuild: Ubuntu 11.04 "Natty Narwhal" - Alpha amd64 (20110131) MachineType: LENOVO 2801CTO ProcEnviron: LANGUAGE=en_US.UTF-8:en LANG=en_US.UTF-8 LC_MESSAGES=en_AG.utf8 SHELL=/bin/bash ProcKernelCmdLine: noprompt cdrom-detect/try-usb=true persistent file=/cdrom/preseed/hostname.seed boot=casper initrd=/casper/initrd.lz quiet splash -- maybe-ubiquity SourcePackage: xorg UnitySupportTest: dmi.bios.date: 12/09/2010 dmi.bios.vendor: LENOVO dmi.bios.version: 6HET34WW (1.19 ) dmi.board.name: 2801CTO 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:bvr6HET34WW(1.19):bd12/09/2010:svnLENOVO:pn2801CTO:pvrThinkPadT400s:rvnLENOVO:rn2801CTO:rvrNotAvailable:cvnLENOVO:ct10:cvrNotAvailable: dmi.product.name: 2801CTO dmi.product.version: ThinkPad T400s dmi.sys.vendor: LENOVO version.libdrm2: libdrm2 2.4.23-1ubuntu3 version.libgl1-mesa-glx: libgl1-mesa-glx 7.10-1ubuntu1 version.xserver-xorg: xserver-xorg 1:7.5+6ubuntu8 version.xserver-xorg-video-ati: xserver-xorg-video-ati 1:6.13.2+git20110124.fadee040-0ubuntu1 version.xserver-xorg-video-intel: xserver-xorg-video-intel 2:2.14.0-1ubuntu2 version.xserver-xorg-video-nouveau: xserver-xorg-video-nouveau 1:0.0.16+git20110107+b795ca6e-0ubuntu1 ** Affects: xorg (Ubuntu) Importance: Undecided Status: New ** Tags: amd64 apport-bug natty running-unity ubuntu -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xorg in ubuntu. https://bugs.launchpad.net/bugs/711093 Title: [Natty,Maverick,Lucid] External monitor connected w/ Display Port power management not working when laptop lid closed _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
