To see if this is already resolved in Ubuntu, could you please test http://cdimage.ubuntu.com/daily-live/current/ and advise to the results? ** Tags added: bios-outdated-2.29 ** Description changed: - In reference to: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg- - video-intel/+bug/1586539 - - Was asked by Christopher M. Penalver (penalvch) to make this new bug - report. - Google chrome intermittently flickers (sometimes even Firefox I found, but very very rarely), and can cause a seizure in some people as it can - flash between black and white 60 times a second. This is a major issue - that needs to be resolved as I'm sure many who are suffering this bug, - feel as well. + flash between black and white 60 times a second. - Please refer to the other bug report which is no "Incomplete" as it goes - into more detail than I have time to honestly type out over again. + WORKAROUND: sudo nano /usr/share/X11/xorg.conf.d/20-intel.conf + + Section "Device" + Identifier "Intel Graphics" + Driver "intel" + Option "AccelMethod" "sna" + Option "TearFree" "true" + Option "DRI" "3" + EndSection ProblemType: Bug DistroRelease: Ubuntu 16.04 Package: xorg 1:7.7+13ubuntu3 ProcVersionSignature: Ubuntu 4.4.0-59.80-generic 4.4.35 Uname: Linux 4.4.0-59-generic x86_64 .tmp.unity_support_test.0: - + ApportVersion: 2.20.1-0ubuntu2.5 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: Thu Jan 19 14:42:57 2017 DistUpgraded: Fresh install DistroCodename: xenial DistroVariant: ubuntu ExtraDebuggingInterest: I just need to know a workaround GraphicsCard: - Intel Corporation 4th Gen Core Processor Integrated Graphics Controller [8086:0416] (rev 06) (prog-if 00 [VGA controller]) - Subsystem: Lenovo 4th Gen Core Processor Integrated Graphics Controller [17aa:221e] - NVIDIA Corporation GK107GLM [Quadro K1100M] [10de:0ff6] (rev a1) (prog-if 00 [VGA controller]) - Subsystem: Lenovo GK107GLM [Quadro K1100M] [17aa:221e] + Intel Corporation 4th Gen Core Processor Integrated Graphics Controller [8086:0416] (rev 06) (prog-if 00 [VGA controller]) + Subsystem: Lenovo 4th Gen Core Processor Integrated Graphics Controller [17aa:221e] + NVIDIA Corporation GK107GLM [Quadro K1100M] [10de:0ff6] (rev a1) (prog-if 00 [VGA controller]) + Subsystem: Lenovo GK107GLM [Quadro K1100M] [17aa:221e] InstallationDate: Installed on 2016-10-10 (101 days ago) InstallationMedia: Ubuntu 16.04.1 LTS "Xenial Xerus" - Release amd64 (20160719) MachineType: LENOVO 20EFCTO1WW ProcKernelCmdLine: BOOT_IMAGE=/boot/vmlinuz-4.4.0-59-generic.efi.signed root=UUID=df32e7f0-11aa-4e43-98d8-fcd5bbeb2c05 ro quiet splash vt.handoff=7 SourcePackage: xorg UpgradeStatus: No upgrade log present (probably fresh install) dmi.bios.date: 03/16/2016 dmi.bios.vendor: LENOVO dmi.bios.version: GNET79WW (2.27 ) dmi.board.asset.tag: Not Available dmi.board.name: 20EFCTO1WW dmi.board.vendor: LENOVO dmi.board.version: SDK0E50510 WIN dmi.chassis.asset.tag: No Asset Information dmi.chassis.type: 10 dmi.chassis.vendor: LENOVO dmi.chassis.version: Not Available dmi.modalias: dmi:bvnLENOVO:bvrGNET79WW(2.27):bd03/16/2016:svnLENOVO:pn20EFCTO1WW:pvrThinkPadW541:rvnLENOVO:rn20EFCTO1WW:rvrSDK0E50510WIN:cvnLENOVO:ct10:cvrNotAvailable: dmi.product.name: 20EFCTO1WW dmi.product.version: ThinkPad W541 dmi.sys.vendor: LENOVO version.compiz: compiz 1:0.9.12.2+16.04.20160823-0ubuntu1 version.ia32-libs: ia32-libs N/A version.libdrm2: libdrm2 2.4.67-1ubuntu0.16.04.2 version.libgl1-mesa-dri: libgl1-mesa-dri 11.2.0-1ubuntu2.2 version.libgl1-mesa-dri-experimental: libgl1-mesa-dri-experimental N/A version.libgl1-mesa-glx: libgl1-mesa-glx 11.2.0-1ubuntu2.2 version.xserver-xorg-core: xserver-xorg-core 2:1.18.4-0ubuntu0.2 version.xserver-xorg-input-evdev: xserver-xorg-input-evdev 1:2.10.1-1ubuntu2 version.xserver-xorg-video-ati: xserver-xorg-video-ati 1:7.7.0-1 version.xserver-xorg-video-intel: xserver-xorg-video-intel 2:2.99.917+git20160325-1ubuntu1.2 version.xserver-xorg-video-nouveau: xserver-xorg-video-nouveau 1:1.0.12-1build2 xserver.bootTime: Thu Jan 19 10:52:11 2017 xserver.configfile: default xserver.errors: open /dev/dri/card0: No such file or directory xserver.logfile: /var/log/Xorg.0.log xserver.outputs: - product id 5571 - vendor CMN + product id 5571 + vendor CMN xserver.version: 2:1.18.4-0ubuntu0.2 ** 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 Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1657875 Title: Google Chrome flickers badly on web pages To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1657875/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
