This bug filing might not be complete because ubuntu-bug was not working at the time. Only managed to send the bug after having found a workaround.
You can see a small history of the problem at http://ubuntuforums.org/showthread.php?t=2213955 Summarising: Xorg on live usb stick doesn't find the ATI card, so it works with the intel one, and it's fine, apparently. After install, the same Xorg finds different list of hardware, including the ATI card and tries to work with it, and dumps core. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to xorg in Ubuntu. https://bugs.launchpad.net/bugs/1299792 Title: Xorg dumping core on Hibrid graphics Intel+ATI Status in “xorg” package in Ubuntu: Incomplete Bug description: Fresh install of 14.04 on Lenovo S540 ProblemType: Bug DistroRelease: Ubuntu 14.04 Package: xorg 1:7.7+1ubuntu8 ProcVersionSignature: Ubuntu 3.13.0-20.42-generic 3.13.7 Uname: Linux 3.13.0-20-generic x86_64 .tmp.unity.support.test.0: ApportVersion: 2.13.3-0ubuntu1 Architecture: amd64 CompizPlugins: No value set for `/apps/compiz-1/general/screen0/options/active_plugins' CompositorRunning: compiz CompositorUnredirectDriverBlacklist: '(nouveau|Intel).*Mesa 8.0' CompositorUnredirectFSW: true CurrentDesktop: Unity Date: Sun Mar 30 16:00:49 2014 DistUpgraded: Fresh install DistroCodename: trusty DistroVariant: ubuntu ExtraDebuggingInterest: Yes GraphicsCard: Intel Corporation Haswell-ULT Integrated Graphics Controller [8086:0a16] (rev 09) (prog-if 00 [VGA controller]) Subsystem: Lenovo Device [17aa:2216] Subsystem: Lenovo Device [17aa:2216] InstallationDate: Installed on 2014-03-29 (0 days ago) InstallationMedia: Ubuntu 14.04 LTS "Trusty Tahr" - Beta amd64 (20140326) MachineType: LENOVO 20B3001VPG ProcKernelCmdLine: BOOT_IMAGE=/boot/vmlinuz-3.13.0-20-generic.efi.signed root=UUID=442725ec-72bc-4adc-852f-3a843af3fab5 ro quiet splash vt.handoff=7 SourcePackage: xorg Symptom: display UpgradeStatus: No upgrade log present (probably fresh install) dmi.bios.date: 10/08/2013 dmi.bios.vendor: LENOVO dmi.bios.version: GPET50WW (1.50 ) dmi.board.asset.tag: Not Available dmi.board.name: 20B3001VPG dmi.board.vendor: LENOVO dmi.board.version: 0B98401 Pro dmi.chassis.asset.tag: No Asset Information dmi.chassis.type: 10 dmi.chassis.vendor: LENOVO dmi.chassis.version: Not Available dmi.modalias: dmi:bvnLENOVO:bvrGPET50WW(1.50):bd10/08/2013:svnLENOVO:pn20B3001VPG:pvrThinkPadS5-S540:rvnLENOVO:rn20B3001VPG:rvr0B98401Pro:cvnLENOVO:ct10:cvrNotAvailable: dmi.product.name: 20B3001VPG dmi.product.version: ThinkPad S5-S540 dmi.sys.vendor: LENOVO version.compiz: compiz 1:0.9.11+14.04.20140328-0ubuntu1 version.ia32-libs: ia32-libs N/A version.libdrm2: libdrm2 2.4.52-1 version.libgl1-mesa-dri: libgl1-mesa-dri 10.1.0-1ubuntu1 version.libgl1-mesa-dri-experimental: libgl1-mesa-dri-experimental N/A version.libgl1-mesa-glx: libgl1-mesa-glx 10.1.0-1ubuntu1 version.xserver-xorg-core: xserver-xorg-core 2:1.15.0-1ubuntu7 version.xserver-xorg-input-evdev: xserver-xorg-input-evdev 1:2.8.2-1ubuntu2 version.xserver-xorg-video-ati: xserver-xorg-video-ati 1:7.3.0-1ubuntu3 version.xserver-xorg-video-intel: xserver-xorg-video-intel 2:2.99.910-0ubuntu1 version.xserver-xorg-video-nouveau: xserver-xorg-video-nouveau 1:1.0.10-1ubuntu2 xserver.bootTime: Sun Mar 30 15:27:16 2014 xserver.configfile: /etc/X11/xorg.conf xserver.errors: xserver.logfile: /var/log/Xorg.0.log xserver.outputs: product id 13549 vendor AUO xserver.version: 2:1.15.0-1ubuntu7 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1299792/+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
