Public bug reported: I have gone through a lenghty update from 10.10 to 12.04. The computer is a laptop with Intel i915 graphics. It is connected to a TV set via S-Video cable. I want a mirror display setup, which used to work fine in 10.10.
At the login screen, both the internal LCD panel and the TV screen work as expected. Both outputs are correctly detected in the "Displays" configuration dialog. After login i get either: - internal LCD only - if I turn the S-Video "monitor" off in the "Displays" tool - TV output only - if I select any other configuration (ie. TV only, both on with mirror, both on without mirror) ProblemType: Bug DistroRelease: Ubuntu 12.04 Package: xorg 1:7.6+12ubuntu1 ProcVersionSignature: Ubuntu 3.2.0-26.41-generic 3.2.19 Uname: Linux 3.2.0-26-generic i686 .tmp.unity.support.test.0: ApportVersion: 2.0.1-0ubuntu8 Architecture: i386 CompizPlugins: [core,bailer,detection,composite,opengl,decor,mousepoll,place,compiztoolbox,move,gnomecompat,vpswitch,resize,regex,animation,imgpng,wall,grid,snap,session,expo,fade,unitymtgrabhandles,scale,workarounds,ezoom,unityshell] CompositorRunning: None CurrentDmesg: [ 34.762406] lib80211_crypt: registered algorithm 'CCMP' [ 45.416016] eth1: no IPv6 routers present [ 215.976045] [drm:intel_lvds_enable] *ERROR* timed out waiting for panel to power on [ 217.224070] [drm:intel_lvds_enable] *ERROR* timed out waiting for panel to power on Date: Tue Jul 10 15:44:01 2012 DistUpgraded: 2012-04-28 07:05:04,422 DEBUG enabling apt cron job DistroCodename: precise DistroVariant: ubuntu ExtraDebuggingInterest: Yes, whatever it takes to get this fixed in Ubuntu GraphicsCard: Intel Corporation Mobile 915GM/GMS/910GML Express Graphics Controller [8086:2592] (rev 04) (prog-if 00 [VGA controller]) Subsystem: Uniwill Computer Corp Device [1584:9800] Subsystem: Uniwill Computer Corp Device [1584:9800] InstallationMedia: Ubuntu 10.10 "Maverick Meerkat" - Release i386 (20101007) Lsusb: Bus 001 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub Bus 002 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub Bus 003 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub Bus 004 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub Bus 003 Device 002: ID 0db0:697a Micro Star International Bluetooth Dongle MachineType: American Megatrends Inc 255/259 Series PccardctlIdent: Socket 0: no product info available PccardctlStatus: Socket 0: no card ProcEnviron: PATH=(custom, no user) LANG=en_US.UTF-8 SHELL=/bin/bash ProcKernelCmdLine: BOOT_IMAGE=/boot/vmlinuz-3.2.0-26-generic root=UUID=9d421d7d-1966-4597-82bc-de00db5a1924 ro quiet splash vt.handoff=7 SourcePackage: xorg UpgradeStatus: Upgraded to precise on 2012-04-28 (73 days ago) dmi.bios.date: 06/06/2005 dmi.bios.vendor: American Megatrends Inc. dmi.bios.version: 2.00 dmi.board.name: 255/259 Series dmi.board.vendor: American Megatrends Inc dmi.chassis.type: 10 dmi.chassis.vendor: American Megatrends Inc dmi.modalias: dmi:bvnAmericanMegatrendsInc.:bvr2.00:bd06/06/2005:svnAmericanMegatrendsInc:pn255/259Series:pvr:rvnAmericanMegatrendsInc:rn255/259Series:rvr:cvnAmericanMegatrendsInc:ct10:cvr: dmi.product.name: 255/259 Series dmi.sys.vendor: American Megatrends Inc version.compiz: compiz 1:0.9.7.8-0ubuntu1 version.libdrm2: libdrm2 2.4.32-1ubuntu1 version.libgl1-mesa-dri: libgl1-mesa-dri 8.0.2-0ubuntu3.1 version.libgl1-mesa-dri-experimental: libgl1-mesa-dri-experimental N/A version.libgl1-mesa-glx: libgl1-mesa-glx 8.0.2-0ubuntu3.1 version.xserver-xorg-core: xserver-xorg-core 2:1.11.4-0ubuntu10.3 version.xserver-xorg-input-evdev: xserver-xorg-input-evdev 1:2.7.0-0ubuntu1.2 version.xserver-xorg-video-ati: xserver-xorg-video-ati 1:6.14.99~git20111219.aacbd629-0ubuntu2 version.xserver-xorg-video-intel: xserver-xorg-video-intel 2:2.17.0-1ubuntu4 version.xserver-xorg-video-nouveau: xserver-xorg-video-nouveau 1:0.0.16+git20111201+b5534a1-1build2 ** Affects: xorg (Ubuntu) Importance: Undecided Status: New ** Tags: apport-bug i386 precise 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/1022979 Title: Intel i915, dual monitor does not work after login To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1022979/+subscriptions _______________________________________________ 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
