I will attach 3 files with the output of xrandr --verbose. However, this is with Precise w/o edgers ppa. I'll first update to edgers ppa, do it again, then later try Raring.
First file is xrandr --verbose when booting w/o VGA external connected (and still disconnected). So this is "baseline". Second file is xrandr --verbose after plugging in VGA external (but having booted w/o it). This is the scenario where the screen is "blank" getting "no signal" even though "Displays" indicates it is connected and "on". Third file is xrandr --verbose after booting with VGA external connected. In this case (and only in this case), the external works properly. -- 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/979748 Title: [expected] VGA monitor only gets signal on boot (no “hot plugging”, no EDID) Status in “xserver-xorg-video-intel” package in Ubuntu: Confirmed Bug description: I am able to get an external VGA monitor (or projector) to work if I start my laptop with it connected. However, if I start the laptop with it disconnected there is no signal on the external. The Displays screen shows the external, and thinks that it is active, but there is no signal being sent to it. This has been a persistent problem since 10.04 (I am now on 12.04.... each upgrade hoping something is improved). I should note that even when it works (starting with display connected), Displays still says the monitor is "unknown" (but it sends the signal). For the correct resolution to display, I have had to add a few xrandr lines for my monitor to my .xprofile file... otherwise resolution is limited to default 1024x768. So, resolution issues can be worked around, but the main issue is that the external doesn't get a signal without starting the machine with it connected. I have tried: adding i915.modeset=1 to grub (also i965.modeset=1 since someone posted that this helped even though lshw shows i915) adding following ppa and doing a dist-upgrade: sudo add-apt-repository ppa:xorg-edgers/ppa (I have since done a ppa-purge on this ppa so all packages have been reverted) Here are the details: Laptop: Toshiba Tecra M10 lspci listings for video: 00:02.0 VGA compatible controller [0300]: Intel Corporation Mobile 4 Series Chipset Integrated Graphics Controller [8086:2a42] (rev 07) sudo lshw -C video listing: *-display:0 description: VGA compatible controller product: Mobile 4 Series Chipset Integrated Graphics Controller vendor: Intel Corporation physical id: 2 bus info: pci@0000:00:02.0 version: 07 width: 64 bits clock: 33MHz capabilities: msi pm vga_controller bus_master cap_list rom configuration: driver=i915 latency=0 resources: irq:46 memory:ff400000-ff7fffff memory:e0000000-efffffff ioport:cff8(size=8) *-display:1 UNCLAIMED description: Display controller product: Mobile 4 Series Chipset Integrated Graphics Controller vendor: Intel Corporation physical id: 2.1 bus info: pci@0000:00:02.1 version: 07 width: 64 bits clock: 33MHz capabilities: pm bus_master cap_list configuration: latency=0 resources: memory:ffc00000-ffcfffff "System Info" shows my graphics as the following Mobile Intel® GM45 Express Chipset x86/MMX/SSE2 ProblemType: Bug DistroRelease: Ubuntu 12.04 Package: xorg 1:7.6+12ubuntu1 ProcVersionSignature: Ubuntu 3.2.0-23.36-generic-pae 3.2.14 Uname: Linux 3.2.0-23-generic-pae i686 .tmp.unity.support.test.0: ApportVersion: 2.0.1-0ubuntu2 Architecture: i386 CompizPlugins: [core,composite,opengl,compiztoolbox,decor,vpswitch,snap,mousepoll,resize,place,move,wall,grid,regex,imgpng,session,gnomecompat,animation,fade,unitymtgrabhandles,workarounds,scale,expo,ezoom,unityshell] CompositorRunning: compiz Date: Thu Apr 12 13:08:21 2012 DistUpgraded: 2012-04-02 03:21:05,114 DEBUG enabling apt cron job DistroCodename: precise DistroVariant: ubuntu DkmsStatus: virtualbox, 4.1.12, 3.2.0-22-generic-pae, i686: installed virtualbox, 4.1.12, 3.2.0-23-generic, i686: installed virtualbox, 4.1.12, 3.2.0-23-generic-pae, i686: installed ExtraDebuggingInterest: Yes, whatever it takes to get this fixed in Ubuntu GraphicsCard: Intel Corporation Mobile 4 Series Chipset Integrated Graphics Controller [8086:2a42] (rev 07) (prog-if 00 [VGA controller]) Subsystem: Toshiba America Info Systems Device [1179:0009] Subsystem: Toshiba America Info Systems Device [1179:0009] InstallationMedia: Ubuntu 11.10 "Oneiric Ocelot" - Release i386 (20111012) MachineType: TOSHIBA TECRA M10 PccardctlIdent: Socket 0: no product info available PccardctlStatus: Socket 0: no card ProcKernelCmdLine: BOOT_IMAGE=/boot/vmlinuz-3.2.0-23-generic-pae root=UUID=969ec06a-f27d-41db-818a-b9a23fe0009f ro quiet splash vt.handoff=7 SourcePackage: xorg Symptom: display UpgradeStatus: Upgraded to precise on 2012-04-02 (10 days ago) dmi.bios.date: 09/08/2009 dmi.bios.vendor: TOSHIBA dmi.bios.version: Version 3.00 dmi.board.asset.tag: 0000000000 dmi.board.name: Portable PC dmi.board.vendor: TOSHIBA dmi.board.version: Version A0 dmi.chassis.asset.tag: 0000000000 dmi.chassis.type: 10 dmi.chassis.vendor: TOSHIBA dmi.chassis.version: Version 1.0 dmi.modalias: dmi:bvnTOSHIBA:bvrVersion3.00:bd09/08/2009:svnTOSHIBA:pnTECRAM10:pvrPTMB1U-02L01H:rvnTOSHIBA:rnPortablePC:rvrVersionA0:cvnTOSHIBA:ct10:cvrVersion1.0: dmi.product.name: TECRA M10 dmi.product.version: PTMB1U-02L01H dmi.sys.vendor: TOSHIBA version.compiz: compiz 1:0.9.7.4-0ubuntu3 version.libdrm2: libdrm2 2.4.32-1ubuntu1 version.libgl1-mesa-dri: libgl1-mesa-dri 8.0.2-0ubuntu3 version.libgl1-mesa-dri-experimental: libgl1-mesa-dri-experimental N/A version.libgl1-mesa-glx: libgl1-mesa-glx 8.0.2-0ubuntu3 version.xserver-xorg-core: xserver-xorg-core 2:1.11.4-0ubuntu10 version.xserver-xorg-input-evdev: xserver-xorg-input-evdev 1:2.7.0-0ubuntu1 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 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/979748/+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
