aldebx, thank you for reporting this and helping make Ubuntu better. As per http://support.lenovo.com/us/en/products/laptops-and- netbooks/thinkpad-x-series-laptops/thinkpad-x1-carbon-type-20a7-20a8 an update to your computer's buggy and outdated BIOS is available (1.22). If you update to this following https://help.ubuntu.com/community/BIOSUpdate does it change anything?
If it doesn't, could you please both specify what happened, and provide the output of the following terminal command: sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date For more on BIOS updates and linux, please see https://help.ubuntu.com/community/ReportingBugs#Bug_reporting_etiquette . Please note your current BIOS is already in the Bug Description, so posting this on the old BIOS would not be helpful. As well, you don't have to create a new bug report. Once the BIOS is updated, if the problem is still reproducible, and the information above is provided, then please mark this report Status New. Otherwise, please mark this as Invalid. Thank you for your understanding. ** This bug is no longer a duplicate of bug 1509846 lightdm crashes on window open in Ubuntu 15.10 intel ** Tags added: bios-outdated-1.22 ** Changed in: xorg (Ubuntu) Importance: Undecided => Low ** Changed in: xorg (Ubuntu) Status: New => Incomplete -- 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/1511615 Title: 8086:0a26 xorg crashes on Ubuntu 15.10 with Intel graphics Status in xorg package in Ubuntu: Incomplete Bug description: Symptom: xorg crashes on windows creation How to reproduce: No 100% reproducibility, however intensively using 2D/3D acceleration triggers the bug (e.g. by opening several new windows and/or menus in a Unity desktop environment) Affected hardware: Intel HD Graphics 4400/5000 etc Affected software: - kernel Linux 4.2.0-16-generic #19-Ubuntu SMP x86_64 - also affected is kernel Linux 4.2.5-040205-generic x86_64 - Ubuntu 15.10 with Unity (because of compiz 2D/3D acceleration) - any other software using direct rendering (e.g. VLC) Workaround: - Disable window animations in Compiz reduces the frequency of the crashes. Use compizconfig-settings-manager for this tweak (sudo apt-get install compizconfig-settings-manager) - Use XFCE or LXDE also reduces the frequency of crashes given that these desktop environments are 2D only ProblemType: Bug DistroRelease: Ubuntu 15.10 Package: xorg 1:7.7+7ubuntu4 Uname: Linux 4.2.5-040205-generic x86_64 .tmp.unity.support.test.0: ApportVersion: 2.19.1-0ubuntu4 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: Fri Oct 30 11:24:21 2015 DistUpgraded: 2015-10-25 22:39:00,819 DEBUG enabling apt cron job DistroCodename: wily DistroVariant: ubuntu ExtraDebuggingInterest: Yes GraphicsCard: Intel Corporation Haswell-ULT Integrated Graphics Controller [8086:0a26] (rev 09) (prog-if 00 [VGA controller]) Subsystem: Lenovo Device [17aa:2218] InstallationDate: Installed on 2014-10-21 (374 days ago) InstallationMedia: Ubuntu 14.04.1 LTS "Trusty Tahr" - Release amd64 (20140722.2) MachineType: LENOVO 20A7CTO1WW ProcKernelCmdLine: BOOT_IMAGE=/vmlinuz-4.2.5-040205-generic root=/dev/mapper/ettox1-system ro splash elevator=noop i915.i915_enable_fbc=1 vt.handoff=7 SourcePackage: xorg UpgradeStatus: Upgraded to wily on 2015-10-25 (4 days ago) dmi.bios.date: 11/20/2014 dmi.bios.vendor: LENOVO dmi.bios.version: GRET42WW (1.19 ) dmi.board.asset.tag: Not Available dmi.board.name: 20A7CTO1WW dmi.board.vendor: LENOVO dmi.board.version: NO DPK dmi.chassis.asset.tag: No Asset Information dmi.chassis.type: 10 dmi.chassis.vendor: LENOVO dmi.chassis.version: Not Available dmi.modalias: dmi:bvnLENOVO:bvrGRET42WW(1.19):bd11/20/2014:svnLENOVO:pn20A7CTO1WW:pvrThinkPadX1Carbon2nd:rvnLENOVO:rn20A7CTO1WW:rvrNODPK:cvnLENOVO:ct10:cvrNotAvailable: dmi.product.name: 20A7CTO1WW dmi.product.version: ThinkPad X1 Carbon 2nd dmi.sys.vendor: LENOVO version.compiz: compiz 1:0.9.12.2+15.10.20151015-0ubuntu1 version.ia32-libs: ia32-libs N/A version.libdrm2: libdrm2 2.4.64-1 version.libgl1-mesa-dri: libgl1-mesa-dri 11.0.2-1ubuntu4 version.libgl1-mesa-dri-experimental: libgl1-mesa-dri-experimental N/A version.libgl1-mesa-glx: libgl1-mesa-glx 11.0.2-1ubuntu4 version.xserver-xorg-core: xserver-xorg-core 2:1.17.2-1ubuntu9 version.xserver-xorg-input-evdev: xserver-xorg-input-evdev 1:2.9.2-1ubuntu1 version.xserver-xorg-video-ati: xserver-xorg-video-ati 1:7.5.0+git20150819-0ubuntu1 version.xserver-xorg-video-intel: xserver-xorg-video-intel 2:2.99.917+git20150808-0ubuntu4 version.xserver-xorg-video-nouveau: xserver-xorg-video-nouveau 1:1.0.11-1ubuntu3 xserver.bootTime: Fri Oct 30 11:09:12 2015 xserver.configfile: default xserver.errors: xserver.logfile: /var/log/Xorg.0.log xserver.outputs: product id 1048 vendor LGD xserver.version: 2:1.17.2-1ubuntu9 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1511615/+subscriptions -- Mailing list: https://launchpad.net/~desktop-packages Post to : [email protected] Unsubscribe : https://launchpad.net/~desktop-packages More help : https://help.launchpad.net/ListHelp
